Hey Guys!

I just switch from CC3D to Naze 32 Acro, I was trying to fit the board with a 3D printed case I found somewhere online, but the case alone measured about 5/8" height, and this made it kind of hard to fit into reduce spaces, like in my JPay 240. So i design this new case in solidworks and just finished printing the first case, I was able to get it to 3/8" height overall and gives me an extra 1/4" on top.

Here's some pics, if somebody needs one hit me up and I'll get it done... :)

Hi,
Could someone explain to me what is the difference between motors:
FX2206-13 2000kv and FXC2206-11 2350kv?

Why they are both cheaper than before on getfpv site?

Someone know when products for QAV250 will be available on getfpv? (motors/frame/case)

Actual case will fit new frames? Will there be new boxes?
Thanks!

The Lumenier motors follow the naming scheme of:

FM -- our lower cost motors. These motors are still very high quality motors, but the bearings are a bit lower quality making the overall motor a little bit cheaper
FX -- FX designates our highest quality motor. Best bearings, assembly, etc.
FXC -- The "C" in the name indicates that the motor bell has the facility to mount flat carbon fiber props. These motors also come with a prop adapter that can hold standard motors

The numbers indicate the stator size and KV rating. For instance:
2206-13 2000kv
This is a motor that has a stator that is 22mm in diameter and 06mm high.
The -13 means that the motor has 13 winds on each stator pole, which then results in 2000kv.
The more windings, the lower the KV, the more torque the motor has
The less windings, the higher the KV

Hi zitom,

thanks! If that the case I can assume that revo offers a better flying experience.

If that the case I can assume that revo offers a better flying experience.

One of the TauLabs developers says that Revo has more sensor noise (http://buildandcrash.blogspot.ru/2014/10/reflecting-on-four-years-of-development.html) than CC3D and doesn't fly as well as cheaper boards. Also, it's overkill for minis.


It also resolved the question of tuning since it tunes up and flies very well and didn't have the same sensor noise as RevoMini.


RevoMini (which became known as Revo) was a stripped down (in terms of connectivity) version of Revolution with an integrated modem designed by David. It was good and bad, too.


I ended up being quite unhappy with the flight performance of Revo (I could never get it tuned as nicely as CC3D). There was ultimately a question of whether the problem was hardware or software (although the same software was used on full Revolution, so that wasn't really a question in my opinion). There was also an issue that Revo wasn't looking like open source hardware and there were a lot of political problems within OP (such as doing a preorder for a board that didn't fly well).

So, think twice before choosing expensive Revo for your mini. CC3D with the upcoming OpenPilot 14.10 version would be perfect in Acro+ flight mode. No need to pay extra for the board which cannot be tuned as well as CC3D even by the developers of this board.

Helidirect in USA has the G10 version in stock.

To be clear -- there is no new QAV250 coming out. The frame stays the same -- both G10 and CF.
We are coming out with "new and exciting things" for the stock QAV250 frames. Large volumes of the frames are in production and will be available soon. The "new things" will be announced very soon.

Lumenier products are now available on Amazon -- sold and shipped by Amazon. Prime shipping available as well. They have a few ARFs and QAV250s frames left. Go snap them up. Search for QAV250 -- make sure it says "by Lumenier" under the product title as there are a bunch of clones on amazon sold by "marketplace vendors".

For me neither, the NAZE 32 ACRO wins all they way!!!!!!!!!!!!!!!!!!

CrazyCoder
17th November 2014, 03:33 PM
It will change soon. CC3D can be purchased for $15 and the next firmware update will have Acro+ mode which is similar to MultiWii rate mode.
If you don't like it, flash TauLabs which already has MultiWii/Baseflight Rate mode since yesterday (in nightly builds).

If you fly Acro, it should be very similar to Naze32 with these firmwares.

Sounds to me that either there will be stand offs to set the motors higher than the top plate, thus bigger props.
Or, more than likely, some kind of bolt on arm extenders for the stock frames. My money is on arm extenders and I'm really interested in that idea.

JG-rn
18th November 2014, 09:16 AM
Or angled motor mounts

Skerts
18th November 2014, 10:43 AM
That won't help much with 7" props though.
I originally thought we'd see a new bottom plate with longer arms but Tim is saying that there's "no new QAV250" and he mentions "stock frames" so for 7" props to work in those examples, bolt on arm extenders are the answer, allowing us to mount our motors a little further out and giving us more space to spin bigger props.

xjet
18th November 2014, 01:44 PM
Or how about props that have a shorter blade on the side that faces the frame and a longer blade on the side that faces away.

Oh... hang on... that won't work ;D

I'll like them too. I call them "food processor blades". They are super stiff and thick. Overall well balanced with a nice clean sound. The pitch is not overly aggressive, yet provides more bite than a GemFan 5x3. One thing I noticed is that they immediately break off at the root of the blade if you touch something since they are so stiff. They don't chip -- just break clean off. Not sure that's good or bad, just different from the soft GemFan 5x3. Definitely a prop to consider. I fly them on Lumenier FXC-2206 2350kv

Sure you could do a 1800 4s if you had a enough weight on the front to counter it. A GoPro counters the weight nicely.

I'm not saying this is the new release but it's Charpu's trasher QAV250. Notice the extended arms, 6" prop, and FAT 4S lipo. I believe it was either 1600mah or 1800mah. Either way, he flew it like it like he stole it!!!!

I guessed bolt on arm extensions last Monday but Tim said they were just replacements since Charpu broke the prototypes so as simple as bolt on arm extensions would be, I'm not sure what to think about them anymore.
I still don't get the tilted motor guess, looking at the angle of Charpu's GoPro, his motors aren't tilted (I don't get why you'd want them to be?)
Speaking of the GoPro, that mount his is on looks new so we could guess that the GoPro mount is another of the new and exciting things. I think my money is still on arm extensions too since it's simple and the base frame stays the same.

Yes, Charpu really is a class act...very humble and very nice. The only way I know who he was is because I recognized his flying style and his signature turns which somewhat resembles a split-S maneuver with many other crazy flips and rolls mixed in. I can say that watching him fly was very motivating. I wasn't able to fly along side him because our video signals were crossing so we took turns flying. After watching him fly, I tended to go balls out and pushed myself. Needless to say, I crashed quite often but then he had some good crashes also. It's just like they say, if you're not crashing, you're not pushing yourself hard enough! In short, I have a long way to go if I want to fly like him but maybe some day!

You are correct. He had a 600TVL and the GoPro. Basically, there was nothing fancy with his rig other than the extensions and 6" props. He said it was "light and fast" but it sure looked beefy to me especially with that GoPro up front and the fat 4S out back. Maybe "light" is relative to what you have powering it. 6" props being pushed by a fat 4S lipo and 18amp ESC's would make most 250 - 300 quads feel "light". Then you have to factor in his mad skills!!!

Funny, I was thinking the same thing when I was looking at it but then the $79 price tag of the Mobius is hard to beat. I actually trashed my Mobius Wide Angle lens when I flew into the hoop at full throttle. It was like an insurgent beheaded by QAV like a hot knife through butter!

Yep... when you go to 6" props and 4S, the damned things seem to "float" so the extra weight of a bigger battery actually makes them easier to fly in proximity situations when trying to duck under overhead obstructions.

As for the GoPro, on 2nd thought, I'd rather stick to the mobius for a while and add dead weight than taking the risk of smashing my GoPro into pieces - which is not a matter of if but when ;)
That being said, even with 1300mah 3S, I feel like the mobius is not heavy enough to counterbalance the battery weight. CoG is supposed to be at the center of the X, right?

Why don't you guys try strapping the battery on the bottom, like a landing gear?
You could then adjust it for cg and the way we fly with the nose tilted downwards for fast forward flight, it would be on the bottom. Out of the air stream causing no extra wind resistance. I wouldn't imagine it would be any less safe than flying a blackout with the battery on top.

I may try exactly that because I have heli landing gear and it makes plenty of space for an under-slung battery. It may even improve handling with less weight at the extreme ends of the chasis.

I haven't tried it, but its gotta be better than having the cg far aft, or stacking gopro or lots of other weight on the front to balance it out. Besides when I crash I'm going so dang fast it's flipping and flopping every which way, I don't think it matters where the battery is. I have more crashes than landings anyway.

I tried some 20A Afros and they were crap. Real issues with some 2300KV motors (even on 3S) -- to the extent that the quad would twitch noticeably in a hover and flip (through loss of motor sync) if you tried a full-throttle punch-out.

I'm reflashing them with BLHeli to see if that helps.

25th November 2014, 07:54 PM
Finally!! Let me introduce you to "new and exciting things" for the QAV250!!!

Thanks for staying with us as we were working on releasing the below 3 accessories for the QAV250. Having seen so much interest in how Charpu is able to produce the speeds we see in his videos is absolutely fantastic. We first have to re-state that Charpu is an immensely talented pilot. Like Juz, he is a fearless artist that is coming up with new ways to fly every time he goes up in the air. Lumenier has been working closely with Charpu to develop a number of products to make his airframe as fast as possible -- so fast, that many video comments are questioning if his videos are even real or if they are sped up. Well, they're not sped up.

So, without delaying you any further, here we go.

1.) The new Angled Motor Mount Extensions for the QAV250

To enable the QAV250 to mount 6" props, we needed a longer arm. In addition, we wanted to angle the motor so that the frame does not have to pitch towards the ground at full speed. Flying at a shallower angle of attack makes the airframe much more aero dynamic, thereby improving speed. Mounting the motors at an angle is not something new, but our solution combines an arm extension with an angled motor mount in a single machined part -- something new and innovative we think. The solution we came up with is an aluminum extrusion that is CNC-ed to achieve a single part that solves both issues. With these motor mounts, you have ample clearance to mount 6" props. You also get a 10 degree motor angle. The part is strong, light, and a single piece that bolts onto the QAV250. The mount attaches to the stock QAV250 airframes with 4 screws. No nuts required. The motor then attaches to the mount as usual. The way the part is fabricated and the combination of angled motor mount with arm extension is unique. Pre-Order is now available with a scheduled release date in the 2nd week of December. The first production run we can get done before Christmas is very small. If you're interested in this product, I urge you to place a pre-order.

2.) Aero Guard for the QAV250

Another way to increase speed is to continue to decrease drag further. The new Lumenier Aero Guard achieves that in an elegant way. The Aero Guard is a single, laser-cut part fabricated from rip resistant material that slides over the QAV250's aluminum spacers. In addition to improving aerodynamics the Aero Guard also protects the airframe's electronics. See picture above and below. Now available for purchase.

3.) New Lumenier FX2208-9 2000kv Motors

With the increased thrust a 6" prop configuration enables, more powerful/heavier motors become practical. We are releasing the FX2208-9 2000kv Motors that produce more torque and thrust than smaller 1806 or 2206 motors. These motors are also rated for 4s, which smaller motors typically are not. The FX-2208-9 2000kv motors will become available in December. Pre-order is now available.

I've got the 12a ultra lite's and they have BEC's, just refuse to sync and work right. Keep having the throttle jump on me from barely a hover to full tilt unless I set my throttle curve to end at 35% hah Going to try and reflash with another version of simonk if I can and see if it helps otherwise I'm switching to something else

The 2208-9 motors will pull more than 12 amps on 4s with 6" props. We are working to release a new ESC in the not too distant future. To angle the motors can be enabled in certain flight controllers. Similarly how you can adjust the yaw value in the CC3D to spin the board by 90 degrees, you can also adjust the pitch off-set by 10 degrees. We'll put some documentation together for some of the typical FCs.

26th November 2014, 02:39 AM
Hi! I've frequented your forums for the last few weeks as I've gone through the paces of designing a QAV250 CF that should hopefully be loads of fun to fly. I would be grateful if the experts could take a look at my parts list to give me any feedback.

The goal of this build is to build a FPV rig with minimal weight and maximized flight time while not suffering too greatly on performance. I know the 6" rotor modification came in today and that could change flight times a lot, but I'm going to just stick with 5" props for now.

Motor
Cobra 2203/34

Rationale: it seemed to have the highest thrust/watt rating of any of the motors. Adjusted for weight (it's .5g lighter than the FXC1806-14 2300kv which comes in the stock QAV250 RTF package) it puts out 4.38 g/W of thrust where the FXC1806 puts out 3.75 g/W - nearly a 17% increase. SunnySky 2300KV's performed just a bit better than the FXC1806-14 (3.76g/W or a 1.1% performance increase when normalized for weight). The RCX ZMR only puts out 290 grams of thrust and although it's more efficient than SunnySky or Lumeniere motors, it's a poor performer.

This is all from data pulled in from various forums and datasheets. Your mileage may vary.

Battery
Turnigy 1400mah 3S 80C

Rationale: after a lot of digging it **seems** that the best battery is the 3S option if I'm going for a longer flight duration. There is a huge increase in performance on using a 4S battery and some of the lower KV motors, but that doesn't translate into efficiency (as far as I've found). I'd love for someone to weigh in on this with a motor / battery combo that has a higher efficiency.

Props
Gemfan 5x3

Rationale: They were cheap. 5x4's seem like they *may* have a lower efficiency on the Cobra motors. I don't have any data to back this up though - just sifting through motor data on the Cobra website that showed 6x4 props performing less desirably but what do I know. I'll test them out and report back unless someone has some data already. Source (http://www.cobrasystem.net/en/product_jcsj.asp?N_product_1jfl_id=1&N_product_2jfl_id=5&id=11)

ESC's
Lumenier 12A w/ Simon K

Rationale: I didn't want to flash my own ESC and I read a complaint or two about the Afro line of ESC's not working too well with Cobra motors. What do you think?

Power Distribution & Conditioning
Lumenier Fury with TBS Core

Rationale: In a word: awesome. No wire mess is a good thing. I love this. TBS Core also includes OSD which is great.

Control
CC3D Atom

Rationale: weighing in at 10 grams and with awesome support it seemed like the simplest solution out there and performs as well as its competitors after a recent (or soon coming - I'm not sure) firmware push.

Tx/Rx
Orange R410X

Rationale: I have an older Spektrum Dx7 DSM2 remote and wanted an Rx that worked with it. Orange R410X has CPPM output which tidies up my wiring, and weighs in at only 2.7g. I could use a Spektrum satellite (with an inline voltage regulator) but its been hard to figure out if the satellites are as sensitive as the Rx's. I wish Spektrum made a receiver that was small and had CCPM and RSSI outputs. No RSSI for my TBS CORE OSD :(

Video Camera
PZ0420M Sony 600tvl Super HAD II CCD Camera (http://www.securitycamera2000.com/products/RunCam-600TVL-DC-5%252d17V-Wide-Voltage-Mini-FPV-Camera.html)

Rationale: Same performance as the famous PZ0420 except it weighs less! High dynamic range, great reviews, and all other sorts of bells and whistles made this one an easy choice.

Video Transmitter
TS5823 5.8Ghz 200mW (http://www.surveilzone.com/mini-5.8g-32ch-video-audio-200mw-wireless-transmitter-fpv-ws1174)

Rationale: I'm still on the fence about this. Pros: It's tiny, weighing in at 7.3 grams with a whopping 200mW output. That's of output power 27mW per gram. By comparison the Boscam 200mW comes in at 8 mW per gram, the popular FatShark 250mW v.3 outputs 6.25 mW per gram. It also has 30 channels that it operates on and is compatible with Fat Shark glasses. Cons: there were some issues with the voltage regulator on the camera causing lines to show up. They *supposedly* have been fixed. They seem to be hit or miss devices with many failures reported. Others love them. (https://www.youtube.com/watch?v=tK2EZSutHRs#t=83)

Video Transmitter Antenna
SurveilZone 5.8gHz Omni Cloud Spirit Circular Polarized Antenna (http://www.surveilzone.com/5.8ghz-circular-polarized-omni-cloud-spirit-tx-antenna-pa1227)

Rationale: Seemed to be the lightest at 10.3 grams (with a protective dome) and cheapest: around $12 for a matched Tx/Rx set. The IBCrazy / Bluebeam / Spironet all seem great, just pricey... Not convinced that spending a lot of money here makes that big a difference.

FPV Goggles
Skyzone FPV & Battery

Rationale: they seem like the best for the money. Still researching this. FPV Goggles seem like an asset that you can take from aircraft to aircraft, better to spend money here as you'll be using them often.

Conclusion

The quad should come in at 419 grams complete, which I believe is pretty light. Anyone build a QAV250 that's lighter? I know there are tradeoffs for this setup, I'm curious to hear everyone's thoughts. Am I missing anything?

Thanks guys!

Nice well done !

If I knew about the aero guard I would not have spent over €30 for my guard ... Love mine but it's expensive for what it is ... The aero is priced very good. grrr

I would recommend to get the aero cos .. First it makes the qav250 look sexier :cool: second it behaves better in flying and like Tim said it protects the electronics.


Tim , Will the FXC1806-14 2300kv work great with these arms ?

Hi! I've frequented your forums for the last few weeks as I've gone through the paces of designing a QAV250 CF that should hopefully be loads of fun to fly. I would be grateful if the experts could take a look at my parts list to give me any feedback.

The goal of this build is to build a FPV rig with minimal weight and maximized flight time while not suffering too greatly on performance. I know the 6" rotor modification came in today and that could change flight times a lot, but I'm going to just stick with 5" props for now.

Motor
Cobra 2203/34

Rationale: it seemed to have the highest thrust/watt rating of any of the motors. Adjusted for weight (it's .5g lighter than the FXC1806-14 2300kv which comes in the stock QAV250 RTF package) it puts out 4.38 g/W of thrust where the FXC1806 puts out 3.75 g/W - nearly a 17% increase. SunnySky 2300KV's performed just a bit better than the FXC1806-14 (3.76g/W or a 1.1% performance increase when normalized for weight). The RCX ZMR only puts out 290 grams of thrust and although it's more efficient than SunnySky or Lumeniere motors, it's a poor performer.

This is all from data pulled in from various forums and datasheets. Your mileage may vary.

Battery
Turnigy 1400mah 3S 80C

Rationale: after a lot of digging it **seems** that the best battery is the 3S option if I'm going for a longer flight duration. There is a huge increase in performance on using a 4S battery and some of the lower KV motors, but that doesn't translate into efficiency (as far as I've found). I'd love for someone to weigh in on this with a motor / battery combo that has a higher efficiency.

Props
Gemfan 5x3

Rationale: They were cheap. 5x4's seem like they *may* have a lower efficiency on the Cobra motors. I don't have any data to back this up though - just sifting through motor data on the Cobra website that showed 6x4 props performing less desirably but what do I know. I'll test them out and report back unless someone has some data already. Source (http://www.cobrasystem.net/en/product_jcsj.asp?N_product_1jfl_id=1&N_product_2jfl_id=5&id=11)

ESC's
Lumenier 12A w/ Simon K

Rationale: I didn't want to flash my own ESC and I read a complaint or two about the Afro line of ESC's not working too well with Cobra motors. What do you think?

Power Distribution & Conditioning
Lumenier Fury with TBS Core

Rationale: In a word: awesome. No wire mess is a good thing. I love this. TBS Core also includes OSD which is great.

Control
CC3D Atom

Rationale: weighing in at 10 grams and with awesome support it seemed like the simplest solution out there and performs as well as its competitors after a recent (or soon coming - I'm not sure) firmware push.

Tx/Rx
Orange R410X

Rationale: I have an older Spektrum Dx7 DSM2 remote and wanted an Rx that worked with it. Orange R410X has CPPM output which tidies up my wiring, and weighs in at only 2.7g. I could use a Spektrum satellite (with an inline voltage regulator) but its been hard to figure out if the satellites are as sensitive as the Rx's. I wish Spektrum made a receiver that was small and had CCPM and RSSI outputs. No RSSI for my TBS CORE OSD :(

Video Camera
PZ0420M Sony 600tvl Super HAD II CCD Camera (http://www.securitycamera2000.com/products/RunCam-600TVL-DC-5%252d17V-Wide-Voltage-Mini-FPV-Camera.html)

Rationale: Same performance as the famous PZ0420 except it weighs less! High dynamic range, great reviews, and all other sorts of bells and whistles made this one an easy choice.

Video Transmitter
TS5823 5.8Ghz 200mW (http://www.surveilzone.com/mini-5.8g-32ch-video-audio-200mw-wireless-transmitter-fpv-ws1174)

Rationale: I'm still on the fence about this. Pros: It's tiny, weighing in at 7.3 grams with a whopping 200mW output. That's of output power 27mW per gram. By comparison the Boscam 200mW comes in at 8 mW per gram, the popular FatShark 250mW v.3 outputs 6.25 mW per gram. It also has 30 channels that it operates on and is compatible with Fat Shark glasses. Cons: there were some issues with the voltage regulator on the camera causing lines to show up.

I'm no expert but I would change a few things if it was me .... As you quoted numbers which makes minimal difference to be honest I would go with the lumenier motors , they perform great and handle 4s very well too plus you get excellent CUSTUMER care from getfpv which is an other plus.
Second , the antenna , it's one important component and believe me don't hold back on it cos you will end up spending more ( don't ask why I know )

The 3rd is subjective I guess but I do prefare the naze32 board at the moment although the cc3d is an excellent FC aswel.

Just my 2c :)

Hally1983
26th November 2014, 09:55 AM
The 2208-9 motors will pull more than 12 amps on 4s with 6" props. We are working to release a new ESC in the not too distant future. To angle the motors can be enabled in certain flight controllers. Similarly how you can adjust the yaw value in the CC3D to spin the board by 90 degrees, you can also adjust the pitch off-set by 10 degrees. We'll put some documentation together for some of the typical FCs.

Hi Tim,

Just a question how is all this extra weight going to effect flight time?

I see the motor weight is 45g each compared to 30g on a 2206-2350kv for example. Then 28g for a set of frame extentions so almost 90g straight of the bat?

For example if we take the 250 CF frame pimp it with arm extentions / new motors as mentioned above / fury board and tbs core blah with a 4s setup.

Whats the ideal total weight going to come in at? Can we still expect 5-6mins of flight on a "fully loaded" qav250 frame!


Cheers,

xjet
26th November 2014, 01:24 PM
Once you go to 6" props you'll appreciate the extra weight. I've found that the bigger props tend to make your average miniquad rather "floaty" which can be an issue when flying proximity. The extra weight of motors and a slightly larger battery will let your quad drop more like it did with the 5" props but you'll still have a whole lot more power-to-weight when you want it and speed will be noticeably increased. The 6" props should also be more efficient than the 5" ones.

I wouldn't worry too much about trying to be so light. I tried to do the same and although it handled very nicely, it tended to be slow at dropping altitude from a hover. This seemed to be important when I would zip through trees and needed to drop altitude quickly without having a chance to drop the nose. I didn't really give it much thought until I swapped out to heavier motors and batteries. I noticed that it dropped much faster and the extra umph from the bigger 4S lipo and more aggressive props more than made up for the extra weight. Also, yesterday I flew in heavy winds and got tossed around a bit. It would have been MUCH worse or outright scary at 419gm compared to 580gm. Yes, it powers around with authority at 580gm but I'm flying with 4s 1300's and 5x4 or 5x3x3 props. I think the big advantage to being light is that important things like arms tend to break less often when youre light. I'm no expert but it's just what I've noticed lately. I'm still learning as well.

My thoughts exactly. Actually, the more aggressive pitch of 5x4 props compared to 5x3 had a "floaty" feel also but I'm not sure if it was just a mental thing until you mentioned it.

I saw those extensions on his rig last Sunday and asked him if those were the "new release" but like the true professional that he is, he said nope and left it at that. It WAS a big hint though. The funny thing is that when I saw how tilted his cameras were, I thought that he should probably tilt his motors but I didn't think much of it. The Gemini Hex came to mind.


Incidentally, He managed to clock 52 mph doing the tight racecourse that we set up. Just think if he had tilted rotors!!

Thats good info but doesnt really answer the extra weight question.

Will we still be able to get 5-6 mins with all that extra weight using say a 1300 4s? Or what size of battery are we meant to use?

Tim can you confirm what you have seen on the test setup regarding average flight time?

Considering building a new CF setup on the 6" 4s new motors but not if the flight time is too low.

Excetly , the other 250 I have with 6inch props is good for cruising but for proximity I do prefare the qav with 5inch tho.

More wieght for the 6inch is needed IMO ..so I ordered bigger batteries.

that will depend on which 6" props you're using ... I have a similar miniquad from a, cough, competitor, cough, running 6" props, 2208 motors, KISS ESCs and 1800 4s lipos. I fly quite aggressively and I get approximately 4-5mins on 6x3 props, and 2-3mins on 6x4.5 props.

Whats great about the new QAV stuff is that it'll give you the 10 degree angle of attack and the improved aerodynamics so that might make all the difference!!

Lets wait and see.

The GetFPV website states that the CC3D Atom Lumeniere Edition supports Spektrum Satellite receivers. Does that require the addition of an inline 3.3v regulator or has that been resolved in this version of the board?

Its the less than 5mins flight i dont want.

Not fussed about 6" props and 4s if thats the case.

So would there be much benefit to using the motor mount extentions with a regular 5" 2206-2350kv 3s setup?

Hi Lumenier :)
Just my 2cents: maybe you could design a simple tilted mount (no extension) for those who want to stay with 5" props / 3s and keep the tiny 250 size but are interested in the aerodynamic improvement of being level when flying forward?

Don't get me wrong, I love the new "things" :)

It would be nice to get some extra feedback on what these new products will do rather than just a statement to say it will make it more aerodynamic etc... for example by what percent will it increase speed? how much more agility for proximity? And my constant moan lol what will happen to flight time.

Some technical specs or estimates based on setups would be ideal.

And for example what is a reccomended setup to buy?

Its becoming a much more competitve market with all these frames and different setups coming out which also makes it difficult for the average joe like myself to decide what to spend the hard cash on.

Hopefully some good fellow will get there hands on one and give a good youtube tear down.

Of course it does.
It improves the aerodynamic of the rig by keeping it level when moving forward.
This and the fact that it also improves the FPV experience (and filming) because the cameras stay level too :)
This alone justifies the few extra bucks investment:)

Hopefully some good fellow will get there hands on one and give a good youtube tear down.

Charpu's vid says a lot about the increase in speed il guess and you can carry a bigger battery to get that added wieght balanced up for flight time.
Obvisiuly if you run on the same 1300mah you will get a hit on flying time

I ordered the extensions...but I am curious if I can run my current Lumenier esc's and Lumenier 2350 motors with the extensions and 6" props. I won't have enough $$ for new esc's and motors for another couple of weeks and don't want to ruin my current motors and esc's if they aren't capable of handling the 6" props.

Here's an alternative to the official QAV250 angled motor mount extensions. It's for those who want a minimal light-weight tilt upgrade without needing to extend the ESC wires. It includes a flight controller tilt platform for an easy plug&play upgrade. Comes with all the necessary length hex button socket screws.

I'm not sure what C rating Charpu was using but you'll need at least a 30c Lipo. I found using 30C with 6x4.5 props the lipo got a bit warm and didn't give as much punch so I switched to the Nano Tech A Spec 65C-130C and they're awesome. They're more expensive, but they also give me peace of mind.

I also really recommend using the 18 amp KISS ESCs. They're slightly fiddly and the soldering pads are too way small - a loose connection or a cold solder joint WILL make cause the ESC to burn out and damage your motor, so you need to be really careful. But, they're amazingly smooth and the response feels really amazing!!

Vbatt pads soldered means the volt of the battery gonna go strait to your cam and vtx... So 4s batt will send over 16v to those...
And yes, it is filtered...
But since youre using imtx, that not gonna be a problem for the vtx, don't know about your cam setup, but carefull if not using 3s...

its a 12v cam, thats perfect i was concerned the vbatt wasnt filtered. so whats the solution for 4s with a 12v cam? Asking incase i ever move to that. Im guessing you would have to add a tbs core or run direct to vtx 5v using a 12v stepup in between?

The equipment i want to use is an imrc 600mw and a cxm1366 security cam so both are 12v and i would want it to be filtered.

Fury board looks quite neat and keeps the cabling under the board and its precut to size. Looking for a neat solution that saves as much weight as possible.

Not fussed about tbs core for 6mins flight not worth it and i wouldnt be going too far, may look at small buzzer for naze32 acro board for voltage alarm.

If you're using 3s, that going to work great! Fury board are very neat and smart! And do not weight much over the original one...I think you're just thinking right, keep it simple and have fun! I'll be downgrading my equipment soon, I'm really tired of fancy things getting bad...I have a great setup, but can't have more than 30 flights before something really bad happens...

If I was you, I just use the 5v 2amps from imtx to power everything up, 5v cam( a new one in your case), board, radio TX, etc...and a buzzer... thats it. Can't be more simple than that...I use KISS Esc, which does not have a 5v BEC to power flight board and radio rx, thats why I would like to source everything from the imtx...

Yeah i use the lumenier 3s 1300s for all my minis they are awesome batterys very happy with 3s and 5inch props.

I just sold my G10 version of the qav250 so looking to build another but CF edition this time no core and simplfied a little.

It flew well on CC3D but what i didnt like was the 5min flight time before the core was left with 20% mAh and that wasnt even fast flight.

The AUW came in at 622g and i had a pnp25 core / lc filter with the rather heavy 2206-2350kv motors.

Now i recently built a zmr250 clone and kept is fairly simple with dys 1806-2300kv motors, afro escs and its AUW is 540g flys for 6:30-7mins before lipo alarm goes at 3.6v and it flys really nice with a naze32 acro.

So im looking to invest my G10 sale money back in to a CF version of the QAV250 with a lighter setup to get the flight time more like the ZMR.

As you mentioned changing to a 5v cam i didnt want to spend more money tbh, but though the fury board could power both cam & vtx on 12v pads while providing filtered video. I dont want to install either an LC filter or a 12v stepup from IMRC to cam either, these are just dead weight and more to fail.

Both the CF 250 and the fury boards seem to be out of stock atm on getfpv too.

Another question you may can help with, is it really worth adding the 2206-2350kv motors rather than the 1806-2300s? Due to the increase in weight, how would the flight time change? Debating what motors to go for on the next build.

Thanks.

I've had RCX 1804-2400kvs, SunnySky 2204-2300kv, and the Lumenier 2206-2350kv motors on my QAV250 frame at various points. Of the three, I like the Sunnysky the best.. They have enough power for my needs and they're low weight.

Its a 64g increase from the 1806-2300 to the 2206-2350 lumeniers so im more interested in how much flight time and performance changes.

In my case im looking for endurance but responsive flight.

Chile Vuela
2nd December 2014, 04:04 PM
Well, more weight == less flight time with the same props. Anything you do to lower weight will increase flight time, as well as improve responsiveness.

Bigger diameter motors (22 series) have more torque than smaller ones (18 series). The 04 and 06 part of the motor number refer to the height. More height == larger magnet area, more torque in the same size motor.

If you want to swing a prop with with a greater pitch (5x4 or 5x4.5) or length (6x3, etc), you'll find that the 22 series motors will give you umph (quicker response, etc). Bigger props will give you more time in the air if you're gentle, but will quickly eat power if you're not.

It's all a trade-off. Best is to experiment to see which motor/prop combination best matches your flying style.

Im thinking possibly 18 series 2300kv for standard CF frame on 3s with gemfan 5" in that case to keep it light with good flight time. But i do have 2x 2206-2350 spare already to start the new build.

So just out of curiosity if we took the cf frame with the 2206-2350kvs would it be able to swing bigger props on 3s with the luminer 12amp escs? Or do we need to drop to 2000kv 4s and 18amp esc for 6" props?

I don't have them soldered on but I do have them and will use them. Did you just take power from one of the spare sets of +/- pads on the pdb? I'm running 4s batteries and since every input to the naze is 5v, I'm not sure if I need to step down the voltage first

Also, to stay relevant to the current topic: I'm running the 2206 2000kv motors with 5x4 props on the cf frame, and at full throttle almost half the time, I'm getting almost 7 minutes of flight time with 1000 and 1300mah batts. 12a esc's, motors and batteries always come back stone cold too which is nice.

Yes, the QAV250 case is waterproof to military spec MIL-STD-C-4150J. The ambient pressure purge valve is there to prevent the case to explode or implode when flying. The pressure purge valve is to military spec MIL-STD-648C if you're interested.

Some time ago I asking for the ability of the qav frame to support cobra 2208. My next project regarding these motors with 5x4hq and 4s. I suppose that these kind of motor (tmotor would be the same) are able to spin 6'' with ext arms.

Yes, the Cobra 2208 will work. Charpu was testing with the Cobra 2204 1960kv before he switched to the heavier Lumenier 2208 2000kv (not available).

Tim, Andy, getfpv, Lumenier test pilots...why can't you provide more details or specifics, or suggestions for your new 6" on 4s setup...or provide any answers to our questions? Do you have other higher priorities at the moment? Many of us are very excited about this conversion. Please just let us know what's going on.

Not to sound like a broken record but +1 we need some answers please.

I personally dont have the money to buy every setup and test so anything you can tell on your findings / testing would help.

The info im interested in is below:

1: Whats the most efficent setup (longest flight time) for a 3s setup using the CF frame.
IE motor / esc amp / prop size / approx auw / flight time...

2: Same question but whats the best performance setup on a 3s

3: Same 2 questions as above but running 4s...

Any ballpark figures or setup advice is much appreciated.

I am by no means an expert but I had similar questions so I can tell you what I tried on my CF QAV250 and what I learned:


1. I got good flight times with smooth flights using EMAX 1804 2480KV Motors on 3S with EMAX 12amp ESC's running 5x3 props and 3S 1300mah NanoTechs. Flight times were well over 6 minutes of cruising and zipping through trees. AUW was around 450-500 grams.


2. For more performance, I went to DYS 1806 2300KV on 3S 1300 mah running 5x4 props and flight times dropped slightly but weight went slightly north of 500g and change. Pretty peppy though. The extra weight wasn't that noticeable due to the extra power.


3. For 4S, I swapped out the ESC's for the Lumenier 12amp N-FET ESC's (4S capable) and kept the 5x4 props or 5x3x3 from Gemfan (yes, playing with fire here but I rarely go full throttle). AUW went up to 550g and then some but again, the extra power made it feel light. It was very peppy and almost beyond my skills but I eventually got used to them. I'm hoping that the new version of CC3D will help tame the beast and make it feel more locked in...so far so good in that dept...Love version 14.10. So far, I've only been able to hover this setup due to weather and time availability but I think I'm sticking to this. I do, however, miss the chill flying ability and slightly longer flight times of the setup in #1. With my current 4S setup, I'm getting about 5:30min of medium aggressive flying... only limited by my skills at this point which is some racing, zipping through trees with some flips and rolls tossed in for good measure. If/When I do more flying at full throttle, I may invest in the bigger Lumenier ESC's like what Charpu uses. Until then, I will just fly it like I stole it. Fried ESC's are the perfect excuse to upgrade but then I don't even have the skills for that yet. I know this is limited info but at least it should get you started. Just keep an eye on KV values, motor temps, prop pitch/size, and ESC limits.


Here is a good link on some motor/prop/battery combos wit thrust numbers. In this thread, there are other links to different motor tests. Good luck!

Thanks for your post. The point of the new accessories is to maximize speed, not necessarily flight time. We are still doing more testing on what good combos are on 4s and 6 inch props as well as our new motors. More data will become available soon.

Flight time won't be to much of an issue for me. Normally I crash after 2-3 minutes in anycase, now I will just do it going much faster when I get the new upgrades. :p

Thanks for the info and the link was good to check the specs for the DYS motors as i have a load of them for my clone builds.
Ive actually just purchased the Blackout Mini H quad for my next project, found a lot more info on setups within blackouts forum post on the open pilot forums and i have found a combo which will suit so we will see how it goes.

I have on order
QAV250
Motors, esc for 4S
InmersionRC 600mw transmitter
Lumenier CS-600 camera
IB Crazy Bluebeam Ultra antenna set
CC3D Atom
Props

Going to use 4S batteries.

What do I need to power the camera, FC and video transmitter?
What else do I need to order? :confused:

I like to use a Core or Core PNP25 if you don't like to solder. What is nice is that it provides filtered power, but just make sure you can at least solder the bridge pads to select the proper voltage for your cam and vtx. You also get a minimal osd which includes voltage and rssi. Voltage is absolutely necessary if you are not flying within earshot of a voltage alarm attached to your lipo.

I'm kind of a fan of using a PNP and making everything plug and play that I can so that I can swap out as many components including the PNP between all of your aircraft as easily as possible and save some money on parts.

You can also just make your own power harness and solder on a cheap power filter, but I have not yet done that yet so someone else can chime in with a good tutorial and parts list.

Well, you already have every...
The immersion vtx provides 5v 2 a, so everything is 5v, just make a harness and should work great...
But, you need a 5v camera, kkk

You can't go simple than that... Rock solid setup.

You don't need a 5V camera. I have the same setup. But I use the ImmersionRC 5v-12v step up regulator, soldered in between my VTX and cam.

Youre right, but I mean that he doesn't need a volt reg if he uses a 5v cam, simple is better...

Bonjour everyone,

I have 2 questions: one for the CC3D nerds and one for the Naze32 maniacs ;)
Don't worry, both are QAV250 related - sort of :)

1- Can you have a telemetry feed between a CC3D and a Taranis?
2- How do you mount a naze32 on a qav250 and avoid wires on the sides?

1- I now have a CC3D and it's perfectly fitting in the belly of the QAV250 with no wires out and room for everything on the bottom plate.
http://i.imgur.com/t0Kot1u.jpg (don't mind the VTx - there's now an ImmersionRC 5.8GHz 600 mw)

BUT I want to use telemetry features of my new Taranis.
And especially for voltage alarm!
(d4r-ii seems to sell like hotcakes these days BTW)

I can't find any information about how to do that.
Any idea?

2- On the other hand, there's plenty of information about the Naze32 telemetry connection.
Like this excellent video:
https://www.youtube.com/watch?v=Q7KpBGDxZQ4
Seems easy as connecting 2 plugs on the board
- 1 from the power board to the VBAT pins and
- 1 from the telemetry pins to the FrSky receiver

BUT I tried to mount one acro Naze32 (on the QAV250 - between top and bottom plates, where its supposed to be).
You definitely need straight pins (and not right angled, as I poorly chose).
The breakout cable connector that goes on the receiver pins (5x2) is so bulky on the side, there's no way you can mount the beautiful aero guards...
It got bad when I tried to replace the receiver pins with right angled pins. When I connected the huge 5x2 connector, I broke 2 solder pads pushing too hard.
Stupid mistake. Need a new board :(

How do you mount yours?
I know Charpu has been using Naze32 and aero guards.
How does that fit?

Sorry that was long...

Thank you for your help :)
Cheers,
Mathieu

Try to mount the naze board rotate 90°, then you will have connectors pointing on top and front; )

Then I have to find another place for my Rx antenna (or a different way to mount it).

Canelo -- there is never a perfect moment in releasing a new version of a product (for any company). If it is critical to you to have the new version and you feel that you are entitled to the new version, please contact us again on support AT getfpv.com, mention our exchange, and we'll give you an RMA number so you can return the previous frame you bought.

It does not get any better than that!

Bonjour everyone,

2- How do you mount a naze32 on a qav250 and avoid wires on the sides?

Simply solder a servo-lead (half an extension) onto the three pads on the side of your Naze32 board (where the bulky multi-pin connector for servo leads would otherwise go) and plug that into Channel 1 (the CPPM output) of your D4RII receiver and you're done.

I don't solder those connectors to the side of the board, I just run the three wires to the receiver and that works perfectly.
