Did you know this bug about the Naza GPS (http://www.dji-innovations.com/compass/submit_rma/?utm_source=dji_web&utm_medium=homepage_kv&utm_campaign=compass_firmware_bug_form)?

I love how the woo kong gps looks nearly like the naza gps. I was freaking out when I saw that I'd likely have to send my gps back since it was just bought.

I noticed the DX8 with ezUHF? How do you like it and how does it fly so far?

So far so good. Yes I've read the horror stories about it but havent had any issues so far. At some point I'll probably move te ezuhf to a tripod to get some distance between the dx8 and transmitter. Still doing a lot is testing.

Hi there
I would like to start fpving with the discovery and I have no idea which transmitter is best for it because I don't want to use my spektrum anymore.
And with which goggles do i get the best quality?

Hi all - I just got some 10x5's fitted to complete my discovery build. (Still waiting for my 9x5's from TBS)

All-in-all very happy with my first flight with it. Trappy, TBS, and DJI have invented a great gizmo ;)

I now need to tune it, and get it "dialled-in".
I have started with the Trappy-standard NAZA gain settings for the 750kv set.
I thought I would start with trying to figure out the side to side wobble.
Could someone get me started by looking at the video below of my first flight and comment on how best to diagnose the wobble (most prevalent when ruddering left) into NAZA gain changes? (or other cause?)

Thanks in advance.
J.

Build includes:
- 750kv TBS motor + ESC's
- Graupner 10x5's
- NAZA + GPS
- EzUHF Rx
- GoPro2
- TBS69
- Lawmate 1w
- Zippy Compact 3700mah 4s

I just changed from Spektrum to Futaba.
I went 8FGs for the price and I see there are newer 14channel transmitters with telemetry but that's what OSD is for so I'm not forking over $600 for the telemetry Futaba transmitters.

Plus if you go UHF your spending more anyways

JBowman, looks like the gains are just too high. I'd go down about 20 points across the board.

JBowman, looks like the gains are just too high. I'd go down about 20 points across the board.

Thanks - I knew I had to go down in gain, just wasn't sure the approximate amount.
This must be due to using the 10x5's instead of the 9x5's - everything else is stock TBS 750kv build.

Cheers,

Anyone using the KK2.0 FC that can Share the settings?
Im having problems after ESC throttle calibraton , one motor is spinning faster than the others and make the disco unflyable.
My setup is:
Tgy 30A ( Flashed w/SimonK FW)
RC Timers 750Kv
Radio: Tgy9x Flashed
FC: KK2.0 factory FW

First calibration was made with the FC, ( 4 ESC's at the same time), then I change and remade the calibration individually w/out the FC, but when I plug everything back the same motor still spinning a lot faster than the others :/

I noticed the DX8 with ezUHF? How do you like it and how does it fly so far?


I wouldnt bother pal, i tried it tonight it didnt go so well it flipped the discovery out broke two props i put it on to naza assistant with the uhf on and if i wobbled the dx8 it showed erratic stick movements.

i had trouble starting off with the uhf beeping because of too low PPM i fixed that then if i moved the 3.5 mm jack it caused jidders so i opened up the dx8 and soldiered the uhf lead direct into the trainer port and still glitched if the disco had been in the air it'd been game over.

also in that vid just look at his RSSI although its the wrong way round its changing RSSI like theres no tomorrow really it should only drop a digit or two one it first goes out of sight

ill be buying a cheapish futaba this week for the EZuhf

I was thinking something around the 8ch range. I cant imagine what you would use the 8ch diversity ezUHF for on the discovery since you only need what 5 ch to basically control it.

I ended up going with a T8FG super through Tower Hobbies with their 3 month EZpay @ $160 a month. That gives me time to see my girl in Dec and still have the radio I want. I'll probably end up selling the DX8 soonish to recoup some of this radio.

Yeh I think I'm going to get the same it's reasonable price and has every thing we need ill most prob get rid of the dx8 even though I like it the only things ill be flying from now is FPV so it kinda leaves it obsolete..


Cool a new disco I like the ESCs being on the top side of the arms and the RX pins above the naza placement but I'm not rating the thought of the arms being custom as if you break one or bend one and you haven't got spares your down time from TBS will be ridiculous also the arms being that strong moves the breaking points into the frame

You need to turn on the RSSI using the little button on the TBS Core (last page of the manual). AFAIK the DORA outputs analogue RSSI ... so make sure you select that when enabling it.

Looking for some advice on antenna placement for the FrSky 2.4 rx.
I believe that the active part of the antenna is just the unshielded part at the end? I measured it and it's just over 3cm which is a quarter of a wavelength so that seems to make sense... I have read it's best to have one horizontal and one vertical, obviously I want to keep them out of the props so I have bent and taped them as below. Any thoughts on this or is there a better way?

This is what I did with mine. I use some of those hard plastic pipes meant for pushrods to hold the antenna at 90°. My receiver is between the two plates, one antenna has been routed up through one of the holes. One has been routed through another plastic tube out to the side.

i will take a picture of mine today, i did something similar to wiseduck but mine is still routed on the top plate to make use of the header pins. on the right i drilled a small hole and put in an antennae tube and the left antennae is routed down the left frame spacer and tape horizontal under the bottom plate

There's an inbuilt sensor on the disco, you just solder the core on the disco and set it up for the right sensor (100A) and you're done

Yes optional as for when you buy the core alone, but there's one built in on the bottom plate of the disco
Then there's a small button on the core which you press according to the flowchart last page of this document to enable the right data display (100a current sensor, which is what's built in on the disco).

don't know what to tell ya, but i've been through 6 f450's and 4 of these,,,,,, i only bought arms from tbs once and the screws were soft as butter. if your having problems with stripping, it's your wrench and your brute force doing it. They just gotta be snug and get a decent tool like a wiha driver. Trappy was suppose to get hard bolts, but as they were shipping up till mid-late summer, they were super soft...... If you bought a real dji kit and got soft bolts, somebody tea bagged you and swapped out your bolts......

They all work, but i pulled em all out and swapped em over to real dji screws from a local dji dealer/builder. These all have a shoulder, grab it with a decent set of pliers and you can get em out with minimal scratching/damage.

Where is the best position to mount my naza gps mast ?
I have EzUHF on the rear and a 5.8 vtx to mount up front on the TBS flamewheel vtx mount.
I'm guessing Half way between the uhf and vtx ?

Well, no tea bags involved in my original my DJI purchase, I can assure you. I've made repeatedly the experience that good screws are not the strenghts of many mass-market products The same poor quality screws come with Align RC helicopters (the T-Rex range). There is a whole after market industry catering for the need arising from this fact. Only if you buy a premium product as for instance the Henseleit helicopter you are getting first class screws and materials - always. Lesson learned: as soon as you find out what size you need, order high grade screws, nuts and bolts from a store specializing in such hardware. Just my 2c - from 20+ years of experience of flying model airplanes.

The problem is also that the TBS screws are longer, the thread in the DJI arms is not always until the end. The org. DJI screws are shorter and have this problem not, indeed when you try to mount the TBS screws then you damage them, also with perfect tools, and the TBS screws are much to soft.

@Kloner: as we are "into it" for approximately the same period of time you'll most probably agree that it is a question of experience. IMHO it does affect how you are building someting if you have built similar things in the past. As mentioned above, I repeatedly came across poor bolts, screws, etc. in dozens of kits. It seems to be the case that companies try to squeeze out the last drop of margin by saving on the suppliers, on the cost of such material. Most of the time it does not necessarily mean that their products (i.e. the F450, the T-Rex'es, etc.) are poorly designed, it is just the accountants saving on production cost post festum.

You have to measure from the center of the GPS to the center of gravity (CG) of the ship. As for the CG: On the bottom of your bottom plate you'll find a mark where your CG should be. Install the battery in a way to get it there. As for the height of the CG, this will be about halfway up your battery - a little bit higher because of the motors and everything you put on top of the top plate. As soon as you have found the CG, you measure from there to your GPS dish. Voilą. Take care that you get your positive/negative values right. The NAZA assistant shows it quite clearly.

Prop holes: I use the 900kv motors, nothing to enlarge with them. If you want to use the NAZA motors: do it step by step. There are dedicated tools for widening prop holes. If you do not want to invest, use sharp drills ( drill manually!!!). But you HAVE TO balance your props afterwards. Step by step - remember!

Hi quick question there,

Yesterday went out for a flight to try my new attitudeSD
I had not checked the quad properly as I crashed last time and put the wrong prop at the wrong place (CCW on top left prop) didn't see that so the quad wouldn't take off and flipped gently (nothing broken), then I checked and saw it wasn't the right prop and headed back home.

There I tested the goggles and the TBS CORE was indicating an always increasing current consumption with only tx and cam powered on (from 15 to 35 A in about 30s), then I cut it off, it would do it for sometime, then I decided to try later. Tried 2 hours after that and no problem any more, normal current consumption for TX and cam.

Could water on the bottom plate could have caused that (short between header pins?)

So you just glue the ESC to the arms and let the wires hang free/loose?

Depends on your flying style. For beginners I would recommend a neutral CG - the NAZA doesn't have to fight a forward tendency and you can hover away ("Kampfschweben", as we call it in German). If you make it a bit nose heavy, you can speed around a little bit easier. But never overdo it! All in all a stabilized Quadrocopter is much more forgiving than a plane when it comes to changes in CG.

kloner
12th November 2012, 03:19 PM
All i do is FFF and in so, you want the cg right where he has it marked to back even more. Tilted up this is like a single rotor, the props, motors, anything up top is now out front. if i grab the frames side where the back arms bolt to the frame, mine sits there perfectly still tilted 45 degrees

if it's nose heavy and a naza, it'll bob up and down in forward flight. too tail heavy and she gets pitchy


http://www.youtube.com/watch?v=RtCm5O5kDQ0

prop adapters are all bent makin jello but you get the idea. there aint even a gopro on the nose, it's an as-10 up straight over the front arms with 4000 mah 4s in the back.......

So I received my new motors the other week and I made a little picture tutorial for you all on how to clean your contacts prior to soldering new ESCS. Don't mess around putting new solder on old corroded contacts!

Get some solder wick... this is super thin stuff, great for picking up solder, bad when you have SOO much solder to pick up, so wind it up like I did and it's like a sponge. Then put it on the blob of solder, put your iron on top, press hard until the solder starts to give away and then try and lightly scrub the area. Press too hard you can cut away the top coat of the PCB so be careful.

Finally clean it up with some ISO alcohol!

Alright here is a little rant about product quality.

I really like the Design of the Discovery, but the screws... seriously guys nobody would have a problem if you you charge a couple of dollars more and put in some good quality screws. The ones you got now are just soft as shit, no matter how good your tools are.

Second thing are the ESCs.
Well it seems like a good idea to solder the connectors directly to the ESCs. Aside from the fact that any mechanical force on them will break them off.
I had one bullet connector come loose with the entire soldering pad, another connector came of during flight. Landing was pretty rough, luckily i was only about 1m above ground, fast forward. How about you put in a short wire between solder pad and connector?

Aside from that i really like the frame, goes together well and the layout is pretty thought through.

Markus

p.s: change the damn screws

Trappy
14th November 2012, 06:32 PM
yes, I know, changing the screws ... ! the new ones are on order, we won't wait until the old ones are out instead we'll start shipping the new ones and throw away the old ones. the ESCs were a purposeful decision. If you attach the ESCs to the arms and don't hang them on the wires they will hold nicely. The newer versions of the ESCs that have been shipping since quite some time also have more solder to attach the bullets.

if they're broken beyond repair please get in touch with me I will make you a generous offer for replacement.

Thx for the offer but there is no need.
ESC is good, the bullet connector came clean off.
So what i'm going to do now, what i should have done in the first place, is take off the shrink wrap and put some more solder on the connectors.
Might hold up better then.
I mounted them to the arms with a cable tie around the ESC itself, so the cables are free.

9" tends to be more a 850-900 kv motor size. i hit 80 amps in atti and it tries ripping my disco apart with 1000kv and 9", i gotta run 8"s and it still hits 65 amp, but the ripping apart look tends to happen around 60 amp so it's right on the edge. in manual, it'd hit even higher

this is 8"

3. How does the Discovery frame adapt to the GoPRO3 ?

4. Would i need anythign else apart from : Flamewheel 450 w/electronics, Naza, GPS, Discovery, CORE ?
Of course I have the vtX , camera, RC and batteries . BEC wouldnt be needed here. Is the current sensor built in frame ?

Thanks !

1, naza cause the wookong is too much stuff, only benefit over naza is it has waypoints, and unreliable at that

2, the esc's are great, simonK are better, but the motors will not carry alot of speed. They are mellow, i'd get something with some bang off the get go so it grows with you.

3, doesn't matter what cam, it sits on a shelf you create anti jello proof

the bec comes with and is part of naza, the current sensor is included in the frame so it's just a core you add to it to read all that. I recomend getting it pre soldered unless your really good solering on extremely small pcb's.... this things compact

not tbs, but a long time fan and user

For the motors, what kind of mounting pattern do the Flamewheel arms have 16x19mm types ?

I will get the dicovery and Core OSD from TBS but might prefer having my Own ESC and power set. Any recommendations ?

yes there 16x19, but i and several others use 19x25 mounting patters and just use 2 bolts per motor

5.8! Smaller stuff and easier to sneak away on a quad. (I use uhf and 1280 personally)

CowboyZ99
15th November 2012, 07:57 PM
I use uhf and 5.8, 500mW with cloverleaf and spw and get good signal to 500m at least. It's true that the antennas are pretty small at that frequency. I tuck mine in front and under the flycam, pointing down. I get less on an aircraft shadow effect depending on it's orientation.

Oh, btw, LeeB, you would need a set of arms

All - Looking for some advice.

Discovery build, 900kV motor+esc kit, no fpv, naza and a gopro, 9" props, what battery setup would you recommend for max flight time?

I'm a newbie so the longer I have in the air i figure the more practice i get :)

With that motor and prop, I'd go with a 4S battery. The 3300 gave me around 8 safe minutes.

I'm currently testing the Zippy Compact 5800, 5000 & 4000 and get roughly 15, 14, 10 safe minutes. However, My bird is a little on the heavy side. You have to consider the inertia and cg with a bigger battery, though. So... Hard to say... I would recommend a smaller battery to learn to fly as it is more agile, being less heavy. Once you're comfortable, then any size that fits would do ;)

I'm new to this, started with RC in august, have both time and money now ;) Maybe this is my mid-age crises :)

My setup is TBS Discovery with the 900KV motors and Graupner 9x5 propellers. I also have the TBS 69 transmitting over 5.8, Immersion 600mW. I use Zippy Compact 4s 4000mAh and OpenPilot CC3D.

I started out with Naza but this controller is so much more fun, and harder to fly with :)

Hi,
Today I made my maiden flight with my Disco and its still alive(-: It was not an FPV-Flight because I encountered a Problem which I couldn't find in this thread.

I have the Lazy Starting Problem on the front right Motor which didn't scare me to much, thanks to the warning here in the Forum.
Hovering in normal Mode is OK beside a light yaw drift. What frightens me a lot is that the copter tilts to the right side if I push pitch quickly. Looks to me as if the right front motor (the lazy motor) accelerates less then the other 3 motors.
Gain settings are still standard in the Naza. Roll Nick 135/135 Yaw 120 Vertical 130 Atti 135/135.

I made a calibration but couldn't test it till now. Dose it help to set my Transmitter to -120/+100% output, how about calibrating the ESC's? Might this cause the tilt reaction of my Disco?:confused:

Anyone know this phenomenon?
Please help.

CowboyZ99
16th November 2012, 08:23 PM
Cyclone, nice going, having all those issues on a maiden flight and it's still alive!

For the yaw drift, I would increase the yaw gain by 25 and see what that does. It will most probably also help with the pitch/tilt. I would increase the pitch to around 200. Vertical depends on your motor/prop combo. Atti could be around 110/100. Hope this helps a bit.

Does the 5.8 work well for you, I hear obsticles can pay havic on the signal?

It's true that the obstacles have more of an effect on the signal than lower frequencies, but, having not tried other freq, I cannot compare. I do have to say that at short range, I can go around a house, get bad video from the other side, but it's still flyable. Going behind trees full of leaves is a no no, but with no leaves is so so... Knowing that, I am carefull of how far I am before attempting to go behind objects. However, I believe that it's true at any freq, depending on the type of obstacle. All to say that 5.8 @ 500mW CP works very well for me, working within it's limitations. So far, I still have clear signal at 1.5km :D

Hi Cyclone,
I agree with Cowboy, I had also some Yaw drift when going vertical so by increasing the Yaw rate I solved the problem and this is true for all the other functions till you reach the point where you get to much wobble.

Ooops... It was bound to happen sooner or later... Glad it happened more later than sooner... Hit an electrical wire at about 100 feet up and crashed in a gravel parking lot. Parts were scattered over a 20 foot radius, 6 feet from my car, LOL.

The GoPro has the video in it, but it's corrupted. Trying to open it in Windows Media Player, it says that the file is already opened. Anyone knows how to repair the file? I would love to see the result of the hit.

Hurts to see what happened to your Disco, Cowboy:( Thanks for your advice on my tilt problem by the way.
Yaw drift is getting better but I still have a the tilt movement to the right if I quickly pitch the copter. I do have the same effect if I Yaw the copter to the right. Yaw left is ok.

I changed the front Motors from one side to the other but nothing changed. Now I switched the ESC but its too dark outside to make tests. What I could see it that the Lasy Motor changed its side with the ESC. So this is clearly related to the ESC. If my tilt problem move with the ESC, I need to think about calibrating the ESC's.
Anybody did this before?

Hope you get airborne in short time.

I could fix a corrupted GoPro-File by removing the SD from the cam an reinstalling it. Gopro cares for the rest, but usually it cuts the last seconds(-:

I tried it for a while, after my Naza flew away. Didn't feel safe with it at all, did not feel in control with this FC. My had GPS and Sonar connected to it but I never got it to fly good. This was probably because of me, lack of competence ;)

For fun flying I then put a CC3D on my Disco. Best choice so far :) Comming from the Naza FC, started flying in august, I have had tough time learning to fly for real but I like it a lot. I'm just a rookie but this FC is a challenge but at the same time so fun :D

DCowboy are those 3 cell Zippys? I need to get some more batteries.I have a bunch of 3cell 2200 and get somewhere around 5 minutes and I am definitely looking for more time and range.

With that motor and prop, I'd go with a 4S battery. The 3300 gave me around 8 safe minutes.

I'm currently testing the Zippy Compact 5800, 5000 & 4000 and get roughly 15, 14, 10 safe minutes. However, My bird is a little on the heavy side.

I made some test Today with the swapped ESC and my tilt problem front/right moved to left/rear)-:
Its obvious that my stability problem is related to the ESC's but I would have suggested to have a front/left tilt problem now by swapping both front ESC's.
Lazy Motor Start moved with the ESC to the other side.

I left the throttle curve flat, i changed the yaw mix. This allowed me to control the unwanted pitch i was getting with yaw control, but it loosen the yaw athority. I use the thorttle curve to keep hover responce less sensative in a high power to weight ratio quads, this setup is rather tame.

I fly more or less always in Atti, I'm new to this :) Tried your settings but I got some oscillations so I lowered the gains little by little to they disappeared.

It flies solid now but I think it is harder to get it yo turn into the turns. Is that because if the lower Yaw mix? Maybe it is about getting used to those new settings ;) After a couple of LiPos it felt better.

It's not so bad a crash. So far, 30$ of parts. All the electronics still work, still have to try the ESC and motors... That kind of crash would have cost more in parts on my Blade SR. That's another reason why I just love this quad :) Crash it good and it's usually a cheap fix :) Yeehaa!!...

For the GoPro video, tried reinserting the card, but the GoPro doesn't see the file anymore. I tried opening it in Windows media player, VLC, Quicktime, NoGo :( I'm sure there must be a corrupted mp4 file repair tool somewhere... just have to look for it ;)

In my experience when a GoPro fails to shutdown correctly whilst recording it will leave the MP4 without header information & no player can read it. The only success I have even had with recovering the video was to get the GoPro to do it. Usually this involves powering the GoPro up with the bad file as the last file written to the SD card.. when the GoPro tries to read it to give you a number of how many video are on the SD card it will give the ERR code on the LCD. When you see the ERR code press the top button ( I think either button works ) & the GoPro should re-write the header info. You will usually lose about 30-40seconds of video prior to the shutdown event.

My GoPRo was doing this a fair bit when I was using it without it's case & sometimes on a bumpy landing the SD card would pop out :( It works best if you see the ERR message directly after the problem occurs so the last file on the SD card is the corrupt one. But a couple of times I have got it to work by getting an empty SD card, writing the corrupt file to it & inserting it into the GoPro to get the ERR message.

Cowboy, you can go to http://mp4repair.org/pwt6/preview.html only to look if there is information in your file.
You can do this in Internet, direct when you enter the site.
When you let your damaged file scan they show you 2 or 3 pick's from it and you know that its repairable.
They ask for real repairs to much money, but at least you know that is must be possible to repair it.
I did not find a program to repair those files....
And sorry for your crash, just after the 200st video....

Hey Cowboy, sorry to read about your Disco crash. You might want to start here to try and recover your corrupted MP4 file.

http://www.goprohacks.blogspot.com/p/how-to-restore-gopro-mp4-corrupted-or.html

After a crash, I was able to recover one of my videos using these directions. I wasn't able to get the crash on video because it cut off the last 10 seconds of the video, but I was able to at least get the rest of the flight. I think there are ways to recover the actual moment of the crash, but I think it takes a little more work.

I've still got my old F450 frame and motors and I'm thinking about getting a kk2.0 board and some simonK flashed ESCs to put together a "trainer". Does this sound like a good idea? I've never flown a kk board so any suggestions are appreciated.

If you want a more lose flying experience drop your Atti gains to like 60 and watch how it acts "more" like a manual mode flight where it doesn't snap back into auto-leveling.

It still wouldn't be as agressive as manual though :shrug:

Just get some altitude while hovering and then flip it into manual mode. Be careful not to give your TX any stick inputs when you flip the switch. Try to maintain a hover until you start to feel uncomfortable, then flip it back to attitude or GPS mode real quick. Another thing you should do while learning to fly manual mode is to program some expo on your roll and pitch to help deaden the sticks a little. There is a big difference between how the multirotor feels between attitude and manual mode. Just remember not to panic and be aware of where your mode switch is located by touch. I started out learning to fly in manual mode a few seconds at a time until I got more comfortable. Now I fly in manual mode the majority of my flights.

you're interested flying manual when FPVing or LOSing? because i find it so much easier when I have my goggles strapped on ;D

my practice before FPVing in manual was doing some LOS tail-in hovering, nose in and some small banked turns. just to get the feel of the sticks on how my quad behaves in manual (and most importantly how I will behave when i'm in a dead spot).. good practise here for me because whenever I am in that "panic situation" my fingers will automatically flip the autolevel switch. faster than my brain could react lol

and yeah, just make your sticks a bit more docile as advise by MidwestRob. it's a bit more forgiving
learning this way.

i use naze32 board and never tried KK2, but seeing series of KK2 videos, sure it should work fine ;D

Thanks for the replies. I do have about -50% expo setup on my Aurora 9 for Manual mode but I still find it difficult to fly LOS. I will try to do it with my FatSharks on and see if it helps. Might get some good crash footage out of the experiment!

Here's a video I made yesterday fooling around at the local park testing out the green vibration pad. Looking forward to numerous flights this week. Only working Wednesday and the weather is supposed to be good (for Novemeber) all week long.

Beside the OSD of the TBS-Core I thought about some additional OS-Infos which are given by the LED or the Naza-Module.
I used a fibre optical cable of my old Sony Stereo and place one end in front of the Naza-LED and the other end in front of the FPV-Cam, with help of an Alumilium Cup. I did this cup by my self but you can also use the plastic protection cap of the cam it self.

Now I am getting the blinking codes for flight mode, Battery alarm and Failsafe.

One thought I was having the couple of times I flew over water would be rather than large enough floats, which could be kind of cumbersome as well as get in the way of the camera, would be to attach a 2 liter empty plastic pop bottle to a short length of fishing line and tie it to the bottom of the frame somewhere. That way if you lost it in the water you could at least retrieve it. If you knew the water was going to be no deeper than x meters/feet you could attach any bright colored floaty thinkg to the line and just have to look for that.

So sorry to hear about the drowning of your Disco, shadow :( that is a lot worse than my mid-air explosion. I truely hope you get it back soon. That is the major fear that prevented me from flying over water until I attached two water buoys to the Disco. Now I have the confidence that it will not sink into the bottom of lakes and rivers. I still need to stop my knees from shaking when I fly over water at some distance since I still don't carry my inflatable kayak with me to go and get it without swimming in cold waters.

Another stupid idea: fly another quad with a fising line with hooks and weight and try to fish it out ... Without drowning that one also... Lol

20th November 2012, 05:54 PM
No good deed goes unpunished....thats the correct saying right?

With as many times as i have flown over water it really doesnt bother me anymore. The bad part is i looked at those inflatable bouys so many times and just never ordered them. I can tell you one thing they will be on my next quad.

Just got an email from the rc club i belong to (it was a small float fly club meet) and they are organizing a disco recovery posse tomorrow morning to get it back. I know a lot of people are against organized fields, the AMA, and such but its times like these that make that $110 a year worth it.

As for recovering the downed girl, have you done any tethered underwater FPV camera setups before? A number of years back I played with small FPV submersibles, doesn't have to be fancy, even a camera in a waterproof container. Just something that you can use for observing the lake bead.

Hey Cowboy, sorry to read about your Disco crash. You might want to start here to try and recover your corrupted MP4 file.

http://www.goprohacks.blogspot.com/p/how-to-restore-gopro-mp4-corrupted-or.html

After a crash, I was able to recover one of my videos using these directions. I wasn't able to get the crash on video because it cut off the last 10 seconds of the video, but I was able to at least get the rest of the flight. I think there are ways to recover the actual moment of the crash, but I think it takes a little more work.

Hey Rob, thanks a lots for the link. I gave it a go and I managed to get the video, without audio, Yeehaa!!... I also had to convert it using VLC to get it to open in Windows Media Player. One slight bad news : It did not record all the way up to the hit and crash :( Oh well... At least it works to get the first part of the video :)

Received my Disco last week and am experiencing the same screw hell as many others. There are FOUR bags of screws that look ALMOST identical, but are NOT.

Trappy: Your support load could be reduced greatly by marking the purpose of the screws on the bags, or at least including a scrap of paper saying "screws are not all the same size... here is what to use for what: etc." I love the assembly video; a picture is worth 1,000 words, but the video does not highlight the screw differences. $0.02.

For current and future builders, here is my TBS Disco Screw and Screw Problem Summary:

ARM Screws:
The included screws are shouldered M2.5 x 6.
ARM Screw Problems: As sir4u and others have pointed out, 6mm is about 1mm too long for the DJI arm and this frame, since the screw bottoms out in many of the DJI arm blind nuts before tightening on the frame. This results in screw head stripping as people try to crank down on the screw to keep the arm from flopping all about, which it never will. I think this is what generated at least some of the "screws are too soft" complaints.

Arm screw solution: NEED: M2.5x5 screws, or a 1mm washer.

SPACER Screws:
The included screws are shouldered M3 x 6. NOTE that the included MOTOR screws are shouldered M3x8, and will happily screw in to the spacers and set in threadlock before you go to mount your motors and discover that the screws you have left are too short.

SPACER Screw Problems: The shoulders on my set of spacer screws is TOO BIG to go through the frame. Although the screw will still hold the spacer, eventually it may loosen as the shoulder eats away at the edges of the frame hole. The hole should really fit the screw better, although one hates to remove additional material from the nubbins that stick out of the frame near the battery. The holes are plated-through as well, which makes reaming out a little trickier.

Spacer screw solution: Get another set of M3x6 screws unshouldered or with smaller shoulders from your favorite metric screw source. Metric screws are less common in the USA, so try McMaster-Carr if your local Ace Hardware or hobby shop comes up empty.

MOTOR Screws:
The provided screws are shouldered M3 x 8. As far as I can tell, there are no problems noted to date with these screws. Yay!

Good luck!

Best,
AerialMike

PS: HOW TO MEASURE YOUR SCREWS:
If you stand up one screw from each bag, you should just be able to see that the 2.5mm screws are thinner and the 8mm screws are noticeably taller. But, for the purists:
Width: With a metric caliper, measure the diameter of the screw. It will be either "almost" 3mm or "almost" 2.5mm. Those are 3 and 2.5mm diameter screws respectively.
Length: With a metric caliper, measure from the tip of the threads to the base of the head (the surface of the head that will touch the plates when you finish tightening the screw. DO NOT measure to the "driver" side of the screw head; this will throw you off! Your screws will be either 6mm or 8mm. Alternatively, set the screws head-down on a flat surface... the shorter batch are 6mm.



The problem is also that the TBS screws are longer, the thread in the DJI arms is not always until the end. The org. DJI screws are shorter and have this problem not, indeed when you try to mount the TBS screws then you damage them, also with perfect tools, and the TBS screws are much to soft.

thanks AerialMike. The problem has been recognized. Future orders (as soon as the new screws arrive) will include 2 bags. One with the current "motor screws" and another with the "arm screws". The one won't fit into the others, so that should greatly help. Most of the confusion revolved around the motor and spacer screws. We've adapted the spacers to accept both screws, and are now phasing out the shorter screws.

I“m with you AerialMike ... this happened to me !! with this butter screws

After having screwed DJI arms, i realized they were wrong :( because there were four bags with similar screws !!!

Trappy and TBS Team:
- why don“t you label the bags ??
- why not TBS69 Cam ($$) bring instructions and screws for mount ??
- why not make the TBS an instruction manual for Discovery with various alternatives for making connections ( ex. EzOsd and EzOsd Curr.sens.)
- why not supply real screws not poor screws ??
Why not ??

You have On-line Shop and a lot of fans !! I am !!

This is one of the things we should all be used to when dealing with multirotor and FPV equipment. There is no really good manuals or one concise area for all the information you need. I think thus far the job team black sheep has done is great and i appreciate all the new products they have brought to market. Hell if they wanted to not take care of their customers trappy wouldnt be here fielding your questions or complaints, at the end of the day its as much of a learning experience for them as it is us.

I didn't spend all that time writing to give Trappy a hard time; he's taken his lumps, he's fixing the problem, so I respect that and think everyone should be moving on. I wrote all that up to help everyone else out until the new parts get into to the distribution channels. I was also surprised to find some of my spacer screw shoulders didn't fit through the plate and thought it was important for people to check their installations.

Although, now that I think about it... Trappy... will there be reasonable-cost screw retrofit kits for recent kit purchasers who have not sourced all of their replacement screws yet?

Nevermind. Answered my own question and that answer is no.
