View Full Version : DJI Naza GPS

I thought I would start a thread dedicated to the Naza GPS Flight Controller. I hope to create a single point for comprehensive troubleshooting of the unit. I have been flying with Naza on my quad for about a month. Last night I installed the GPS device for it. Today I took it out to the field for a test. Over the next day or two I will add photos of the unit, both in the package and installed. I will also post videos as I get the unit trimmed on the Quad.

In the meantime, my immediate results are as follows:

Return To Home - This was a fail :) I set the quad on the ground and plugged in the battery. I let the GPS and flight controller initialize. Once the GPS has acquired a sufficient number of satellites (about 30 seconds tops) I take off. Note that the moment you advance your throttle the Home position is set. I flew the quad out over a grass/dirt lot at an altitude of about 15' AGL (fifteen feet above ground level). Now for the moment of truth. I switch off my transmitter hoping to see the quad climb to an altitude of 20 meters above loss of signal. It should have then returned to my location and after about 15 seconds of hovering, descended at my feet. Instead the props lost power and it dropped like a rock :)

This turned out to be user error. I do not have the fail-safe setup properly with the Naza controller. I have temporarily put the fail-safe position on a TX switch. No longer at the field, I went out to the front yard to give it a try. RTH (Return to Home) IS WORKING but I did not have enough room to let it do its thing so I will have to provide a full report later.

********** Subject: Return to Home **********

1. I would like Return to Home to engage when the quad loses signal from my transmitter. I am currently using a JR 9503 transmitter with an 8 channel Xpektrum DSMX receiver (model to be added later). JR has two types of failsafe. Smartsafe holds all sticks and switches in the last transmitted position accept the throttle which moes to a preset. This is useless for Return to Home since activating it should be switch controlled rather than throttle controlled. The second type of fail-safe from JR is called Preset Fail-Safe. This option reverts all controls including switches to a preset condition that the user defines when the TX is bound with the RX. Note that the Preset Fail-Safe is not available on all JR/Spektrum receivers. As luck would have it is not on the 8 channel unit that I am currently using making it useless for return to home.

Overall so far I am extremely happy with the unit. Like the Naza Controller itself, the GPS unit just works right out of the box (discounting user error). More to come...

********** Subject: Position Hold *************

Objective: The quad-copter should maintain its position (both GPS coordinates and AGL when the sticks are released.

Problem: When the sticks are released the quad enters a slowly descending counter-clockwise circle. The speed of the circle increases over time as does its diameter. Initial diameter is ~10 feet. At a diameter of 20 the pilot resumes control to prevent crash.

Suspected Cause 1: I am flying a HK Talon V1 Frame. The round booms swivel in their mount which means that the motors are hard to keep true and vertical. A tilted motor could be initiating drift. I am not observing problems with the quad's yaw so this may prove not to be the problem.

Suspected Cause 2: I need to re-calibrate the ESC's. I notice that when the quad is idling they are spinning at different speeds.

Suspected Cause 3: The MC position in the setup assistant might need to be tweaked. I left it with default axis values. 6/15/2012 - I started playing with the GPS offset compensation setting in the Naza assistant software. An addition of 5 cm from default on the x and y coordinate made no discernible difference in the way the unit flew. I will exaggerate these numbers and report back.

Final Solution: I found a solution here (http://www.multirotorforums.com/showthread.php?3618-UPDATE-Toilet-bowl-in-NZ-after-Firmware-5.06-release/page2) (Thank you 139 jockey!) In short, the GPS Unit heading position should be rotated ~35 clockwise from the heading position of the Naza FC. This will stop the "Toilet Bowl" effect. This solution was posted in relation to the TB effect showing up after a firmware upgrade to the WKM. Apparently the NAZA inherited it. In anycase I just made a rough adjustment and immediately the toilet bowl effect vanished. It needs a bit of fine tuning as the quad now very slowly slides around a two foot box while maintaining altitude. I am going to consider this a fix.

I am about to mount the system onto a Hex frame and will initially run the NAZA and GPS headings in the same direction to try to repeat the problem on a different platform. I anticipate that this will eventually be fixed with a firmware update.

Backlash,

Hey, thanks for this thread. I just got my first RC anything about a month ago. A witespy quad with the Naza. When I heard of the upgrade & it's features it sounded really cool. Looking forward to hearing your thoughts. I haven't got my video setup yet, just flying LOS, but now I'm wondering if I should get this first? Decisions...decisions... :)

I just got my Naza (sans GPS) in the mail, along with Flamewheel 450 frame (very nice frame) and have just wired it up and now need to do initial setup. GPS and Gator camera mount/gimbal are next on the list, likely the camera gimbal first. Oh, will be FPV'ing this too, before camera gimbal or GPS. I have an SC2000 600 tvl cam and 5.8 gear to go on it, just have to figure out how to get the SC2000 wired up now.

The GPS option is a big attraction to me, more for position hold while doing AP/AV than RTH, but the RTH would be very valuable I can see. Looking forward to your findings with it.

cheers

LOL Yeah, I'm leaning that way. It's looking like my wife & I might be moving. We put an offer on a house in Gresham & it was accepted. Right behind the back fence is a park too. I can picture myself in the back yard, reclined in a chair, flying in the park. I might have to save a while to get the goggles though. But, I have a LCD screen similar to yours that I can use in the mean time.

I'm building myself a set of DIY goggles using a 3.5" lcd I got off Amazon (they have 'em on ebay, but I hate ebay!). $20 for the lcd, $2 for black coroplast, $3 for a wallet size magnifier, a little comfort foam and an elastic band and I'll be good to go. Only problem... they turn to blue screen when the video goes to crap... BUT since I don't fly very far and just get the occasional blip going behind a tree I think I'll be alright. I'll let you know how they turn out!

Has anyone set up a JR x9303/921 combo to work with the Naza with GPS? I'm having some trouble determining which transmitter controls I should configure for the VU, the Atti/Atti-GPS/Failsafe switch, the IOC switch and also have the ability to control at least the Tilt gimbal on my GoPro mount. It's probably a pipe dream that I could do all that and still have pan/tilt control on my FPV camera, but maybe. I'm not a 9303 wizard so I could use any help that someone wants to offer (so long as it's "informed" help).

Thanks,

i am using a 9303 and a ar8000, i do not have my gps as of yet but i will in a few days. I setup my manual and atti mode on the gear channel, and then i use gear mixes to make the idle up switch control my modes. My throttle hold is setup with a mix as well so it activates my fail safe in the naza. I dont have any pan and tilt or a head tracker but if you need 9303 help i can help with the setup.

Thanks J5coat.

Here's how I have it set up right now. I've got everything I need except that I'd love to have the ability to select the FailSafe-RTH mode with a switch as well as having it initiate on radio contact loss. I can set that up in the Control Mode selections but I'll have to lose Manual (which I'll probably never use since it's an AP ship). It would be great to have both available though.

Please let me know if you see anything wrong with the way I've set things up below. I haven't tested it yet - waiting for better weather.


X9303 Switch Select Settings:

Flight Mode – INH
Gear – Flap SW
Flap – Aux2 SW (trim-off)
Aux 2 – Flap Lever
Aux 3 – Aux3 Lever
Aux 4 – Mix SW

921 Channels Connections:

1. Throttle - T
2. Aileron - A
3. Elevator - E
4. Rudder - R
5. Gear - U – Control Mode, Manual/Atti/Atti-GPS or Atti/Atti-GPS/Failsafe (controlled by Flight Mode Sw)
6. Aux1 - Lights on/off controlled by Aux 2 Switch
7. Aux2 - FPV Camera Pan – Controlled by Left Lever
8. Aux3 - X1 – GoPro Pitch – Controlled by Right Lever
9. Aux4 - X2 – IOC – Controlled by Throttle Hold

i had to go read the directions for the ioc, as all i wanted the gps for is rth and position hold for pictures. Looks like that should work for you, just make sure you test everything with it hooked up to the computer first. make sure it goes it the failsafe you want when you turn off the radio and make sure each flight mode is correct and you should be good.

My gps arrived today, it was pretty easy to setup. I am only using the RTH and position hold and they both worked great! The RTH work flawless as well, i tried it at 100m, 500m, and a whopping 1300m! I am flying spektrum and still have yet to have a lockout, but now i dont have to worry about it.

You may want to try "compatibility" mode.. Could very well be that they are not up to speed with all incantations of W8 yet..
Installing from safe mode or a "clean boot" sometimes will stop a pesky service that is interfering with the install..

There actually was a downgrade version.. availability? not sure anymore... You can still purchase XP at a number of sites (79-149$ USD) but I suggest that you make sure you have the restore software for your PC (XP just might not like your new hardware).. Better yet, buy a fresh 2.5" hard drive and just swap it out.. (leaves all your old stuff intact)
Most of the companies I do work for are going to stick with XP for the foreseeable future (and as long as Dell loads it for them on lease machines) :)

Okay, it is a laptop so it may care about the hardware. I'll see what hard drives I can get for it and get a copy of XP... Well, this'll be months out of course, tying up every dollar I have in producing the Honey Badger quad :D

I just hate how when Microsoft comes out with a new OS the local computer stores take the old version off the shelves and refuse to sell the copies they have.

This thread is a little dated, but I figured I'd try it since it's a perfect fit topically.

I'm trying to set up my Naza-M GPS with a spektrum aR500 receiver I happened to have lying around. The Naza manual is unclear on when failsafe will be activated. I can't configure the U channel to move to the "failsafe" position when the transmitter is turned off due to the failsafe limitations of the AR500. (The AR500 disables all channels but the throttle channel, which it moves to the bind-time position of the throttle stick.) That means I can't trigger return-to-home with the switch. I'm OK with that. What I really want is for the quad to come home if the transmitter fails or the receiver goes out of range.

The Naza manual also says that failsafe will be triggered in flight if any of the A, E, T, R, or U channels goes dead, which would occur if the AR500 lost signal. This part seems to indicate that what I want to have happen will happen.

So, I really do NOT want to put my new quad up in the air and turn off the transmitter just to see if return-to-home failsafe works as expected (I haven't flown it at all yet, still setting up!!) Can anyone advise what happens when the Naza encounters AR500-style failsafe (throttle goes to, say 50% position, all other channels have no signal)?

Thanks!

Hi Mike;
Yes I have tried it many times. I have three multicopters that I fly now. I've tested them out with the throttle at 50% and turned off my transmitter. Guess what??? the little bugger came back home and then assented to about 60 or so feet and after about (what seemed a lifetime) 30 or so seconds it just settled down to a very slow descent and landed within about 5 or so feet from where I grabbed the GPS location. I have done this for each of my multicopters just to make sure that home is where it is heading if I should loose power to the TX. Do make sure that you set the compass per DJI manual, else it might not come home...

AerialMike
3rd March 2013, 06:17 PM
Well, I took it out and tried it... but no, when the transmitter is off, the quad just sits in place, waiting for its battery to die. :-) I guess I will have to find another receiver.

Okay, so I'm setting up my FS setup now, and have a couple questions. I've heard the throttle just needs to be above 10%, but it's not going to hover at that throttle obviously, so should I set my FS at 50% throttle? Also, how do I mark home position before take off, or do I have to, or does the GPS do so automatically? I've searched, and read, but get mixed answers.

Okay, so if I leave the IOC box unchecked on the autopilot setup page, then it simply registers where I arm it as home then? And I have enhanced fail safe set to return to home and land, then I'm good?

Remember it will do its own thing and raise or lower itself to its rth height if its not on the ground, so stay away from trees etc.

OK, Thanks. I have noticed that if I plug i the naza and wait for the GPS to acquire sat lock, then unplug it and plug it back in before flight, it tends to hold the lock better. Am I nuts or has anyone else experienced this? If I don't it seems to drift backwards quite a bit.

EDIT: I show everything going into FS in the software as it should. And I haven't even used my GPS yet just for these reasons. I would think 50% way too high.. 10/20% much safer.. Make sure the "low battery" stuff is OFF.. When the battery gets lower in the charge area, it will activate at the least opportune time when you lean on the throttle.. (bad things happen)

IOC is pretty cool, (especially for learning but it sort of hampers your learning curve at the same time.. I use it when I get into trouble and loose my orientation or if I am in a position I simply can not have dumb thumbs..)

GPS "self acquires" on "power up" (usually under a minute) I do not leave the ground until I get "GREEN". There is a flashing LED indicator that you still need to lift off and hover until it goes out..

I have noticed that the GPS lock work best after a few minutes of regular flying. Just after takeoff it can drift a little and be unprecise. I guess it gets better coordinates after some forward flight ?
It is rock solid after this.

My failsafe/RTH works flawlessly. But it might jump a little on touchdown. And I had to recycle the power before I could arm it again. But I have learned that you I must go into manual mode to disengage the RTH.

I would think 50% way too high.. 10/20% much safer.. Make sure the "low battery" stuff is OFF.. When the battery gets lower in the charge area, it will activate at the least opportune time when you lean on the throttle.. (bad things happen)

IOC is pretty cool, (especially for learning but it sort of hampers your learning curve at the same time.. I use it when I get into trouble and loose my orientation or if I am in a position I simply can not have dumb thumbs..)

GPS "self acquires" on "power up" (usually under a minute) I do not leave the ground until I get "GREEN". There is a flashing LED indicator that you still need to lift off and hover until it goes out..
*(copy the flashy LED codes out of the manual and carry a copy)

Good deal, thanks Randall. I don't use IOC as I have been flying for a while now (watch that statement bite me next time out LOL), and feel it would just mess me up at this point. I'll redo my throttle settings this week, as it will be weekend before I get any stick time most likely.

Yeah, I need to go through the manual and make an LED cheat sheet actually, way too many to remember off the top of my head.

does it show going into failsafe in the software?

No, it never does. In flight, it does not flash orange when I turn off the transmitter either. I do have the return to home radio button checked. In the air, it went from two green flashes to one green flash when I turned off the radio... I think. It was kinda hard to see. I didn't leave the ground until I had a single green flash and no red flashes. I took off in gps atti mode.

I guess my followup question is this... which LRS works best with the Naza? I have a choice of DragonLink or EZUHF. I have a Spektrum DX8 transmitter. I hear some have had difficulty with the wiring, but I can't buy another transmitter AND an LRS system right now. Which LRS works best with Naza failsafe when the transmitter dies?

panzlflyer
4th March 2013, 10:32 PM
One of the issues I ran into when setting up for guys was with a Spektrum reciever it is possible to have 2 types of fail safes on some of the recievers.
One is position hold (this does not work with the Naza) the other is a position you can choose which does work, I think its Smartsafe or Failsafe, you choose the type by how you use the binding plug.
With the correct type Failsafe set you simply bind with your RTH switch in the correct position. I know it works with an Ar7000/8000 not sure about the smaller ones as I am Futaba/DLink these days
Dx8 does not supply power down the trainer port so you will need to supply power to either Lrs.
Probably cheaper and easier to get a Turnigy 9x with either Lrs or a used Futaba 9c.
PPM Sum does not work with Jr/Spektrum as the Naza uses Futaba channel numbering and unless you can re order it in your radio you will be stuck using normal jumpers.
Failsafe is not an issue with the Dlink its easily set, pretty sure EZUhf is the same

RandallJ
5th March 2013, 12:40 AM
? not sure I understand..
The NAZA has 2 failsafes *they fall in between ATTI and GPS I think (been a while since I looked at the control center) Do not reorder them or you wont get it to work either (someone tried this and posted)

I have 2 profiles for the DX8 (one I know works, the other have not loaded and tried yet).

do a search and there is a thread with the spm and a link to the other spm at RCG..

panzlflyer
5th March 2013, 07:58 AM
Randallj,
I am talking about where the radio reciever moves the output to when it failsafes.
As long as the slider in the software moves to either of the Failsafe positions it will work, ive setup a dozen of them.
Ppm Sum is all channels down one wire, which the Spektrum system cannot do.
Jr/Spektrum have different channel ordering for Ail/Elev/Throttle and Naza if using ppm sum expects a Futaba order.
The post you linked to on the other site mentions the Failsafe as only working with some spektrum recievers about halfway down.

RandallJ
5th March 2013, 09:50 AM
Guess I am lost.. do not understand the radio systems well enough yet.. I was unaware that there were 2 types of fail-safes even.. back to the manuals... just when I start seeing light..

Zeeflyboy
5th March 2013, 03:05 PM
Randall, your DX8 only has the one kind of failsafe - don't worry about it ;)

Some systems have different types of failsafe...

The ones I'm aware of:

- hold position; channels will hold the value last seen before radio loss.
- single channel failsafe position; one channel only will go to the previously set failsafe position. The rest will either hold position or go to neutral.
- failsafe position; the one most people are aware of these days... All channels will move to the previously set failsafe positions upon radio loss.

panzlflyer
5th March 2013, 03:18 PM
The failsafe position in a Spektrum system is determined by the reciever at bind, this is why the Naza will not go into failsafe.
That is because a reciever that is either Bound for Smart safe or does not have the other failsafe just drives the reciever output to neutral and throttle to idle on losing contact.
What you want on the Naza is the reciever to move the RTH channel to a pre determined position to tell it its in Failsafe.

The 2 types below are applicable JR/Spektrum
Found on newer Ar7000/8000s etc

Smartsafe: If the bind plug is left in position throughout the process (Flight Ready Bind above), the system will be set for Smart Safe. If signal is lost, only the throttle channel will go to a preset position.

Failsafe: If the bind plug is removed before the TX is turned on and bound, the system will use FailSafe settings. In this mode, if signal is lost all channels will go to their preprogrammed positions ( This is what you want from your reciever for a Naza)

NOT a function of the DX8 but the reciever.


Futaba the failsafe is set in the radio and updated to the reciever.

AerialMike
5th March 2013, 07:15 PM
I have the AR500 receiver; it has only one failsafe mode, which is "throttle goes to bind position, all other channels off." The cheapest Spektrum receiver I could find that supports an "all channels go to their positions at bind" is $90. I'm not going to pay half the cost of an LRS for a 2.4GHz receiver just to get the failsafe to work.... I'll just go for the LRS. :-)

Oh, I think hobbyking sells an Orange receiver with "all channels to go their bind-time positions" for $20 or so, but... I'm not willing to risk the quad with a $20 receiver. :-)

The disappointing thing is that on page 22 of the Naza manual it states that the Naza will go in to failsafe if any of the channels go dead... but this must be an error.

panzlflyer
5th March 2013, 07:23 PM
That is the trouble, the channels dont go dead on the Spekkie recievers they are holding a neutral position, so I guess the Naza sees it still alive..
If you are going to fly any distance at all and use a vtx other than 5.8 you are better off going uhf imo.
My buddy swore he wasnt gong to fly far enough to worry about 2.4 control...........2 weeks later after using goggles he is at its limit bugging me about LRS!

RandallJ
6th March 2013, 01:49 AM
now I am really confused.. lol.. I do know if I turn off my radio, the NAZA software shows the system going in to "failsafe" and that triggers the "RTH" Also if I throw the gear switch, it overides any other mode and goes to failsafe and RTH again..

I have a Turnigy 9X with LRS to set up on it and now I am second guessing that move.. Futaba 9C might be in my future yet.. :)

And I thought single rotor flybarless systems were complicated to get setup properly.
The learning curve on this stuff is pretty steep.. First you got the planes, and you may have to build it. Then you gotta power it and control it.. (not that there are more than a couple options and reasons for each there). Then you gotta fly it.. (hell the guy down the road made it look easy, how tough could it be really?)

Then the avionics.. in some respects, more complicated than what was in our full size plane.. heck, we never had a RTH, loiter or any of the fancy auto control stuff. Wing leveler, basic VOR autopilot.. whoopy..

And then we add the telemetry with FPV... eegads.. just how much stuff can you learn in a month or two... Getting around Barber on the Busa was easier..

I am going to go build a "EggBot (http://www.jameco.com/Jameco/workshop/productnews/egg-bot.html?sp_rid=Mzk3OTU3MDYwNzUS1&sp_mid=4772188)"

Zeeflyboy
6th March 2013, 11:10 AM
If its any consolation Randall, if you get something like the EzUHF it only has one type of failsafe - all channels to their preset condition. Nothing to get confused about lol.

What radio you use, and what any of its failsafe settings are (speaking futaba style failsafe menu here) is irrelevant when it comes to the failsafe condition of the LRS system... That's something important to remember/understand as it popped up here recently.

Didn't know that some spekky rx's had both types of failsafe - learn something new everyday!

WNCmotard
6th March 2013, 11:27 AM
@Randall - totally agree, hustling the bike around is easier. Maybe because it's second nature at this point though. That eggbot is pretty cool!

Luckily, my failsafe setup on the radio part was super easy, just put everything where I want it set, and push one button on the RX, done.

I found out about Spektrum failsafe/Naza the hard way! Guy asked me to set his Dx8 combo up, "piece of cake" I think, 2hrs later finally figured it out! I used to fly Spektrum for a while when Futaba did not have 2.4 but had forgotten the pesky failsafe issues.
I fly Futaba 2.4 and Lrs, Dragonlink and EzUhf are really easy to set failsafe.
You all will get there in the end, if there was nothing to learn it would be boring.

Well, I ordered an EZUHF setup from a couple of places today (nobody had it all in stock), so I'm on my way, I hope! My next concern is flaky trainer port action on the DX8. Not sure I want to open it up and solder to the TX module inputs, but I suppose I can if I have to. I like the jack/plug idea, but I can never seem to source the matching jack/plug.

Yeah maybe not flick the BIG switch, I mean the ultimate goal is to not go there if at all possible, and if the RTH switch works for complete video drop outs then that's really what your after in our game.

I have just rebuilt mine and have more patience this time around so I've been bench testing a lot of stuff. The naza most certainly changes to failsafe made when it on the bench and I cut the transmitter power. So that's comforting.

I would not turn my radio off for any reason, not unless somebody had a gun to my head. Not because I don't believe the tech won't work, but because I believe in gremlins... and my own ability to forget obvious things that would prevent it from working.

If I were a real pilot, the last thing on my pre-flight checklist would be to have somebody else redo my pre-flight checklist. Haha. The radio stays on! I'm not chicken, I'm more like the cowardly lion from Oz. It's more pathetic than a plain old chicken.

AerialMike
10th March 2013, 09:36 PM
I know it's not a favorite combination, but the DX8 is what I have at the moment, so I've been working with it and thought I'd let folks know how I'm making out. Maybe someday I'll be done buying more important system components and can get a futaba transmitter. But, not right now.

After some finagling, I have things working pretty well, I think! I have my flight mode switch mapped to the gear channel, which is plugged in to the U port on the Naza. I was able to adjust the Gear channel throws such that the three positions map to Manual, Atti, and GPS Atti solidly. I have a mix set up for Aux 1 (flaps/gyro) such that no matter what the position of the flight mode switch, moving Aux 1 out of the center position (up OR down) triggers failsafe. Perfect!

I was able to set the failsafe of the EZUHF without issue. If I unplug the DX8 from the EZUHF but leave the EZUHF powered, the receiver goes in to failsafe and so does the Naza. If I unplug the EZUHF transmitter from the battery, the receiver goes in to failsafe, and so does the Naza... Perfect! Couldn't ask for anything else.

I have heard about the potential issues with the trainer port on the Spektrum radios, both with possibly low signal level and possibly glitchy output from the connector. I have experienced neither of these issues so far. While the photoplug interface makes me a little nervous, the failsafe looks like it's working well enough that I am not going to worry about it in the short term.

The ONLY concern I have is that the "Frame Period Delta" figure is quite high, 15 to 20 us in the few tests I did. I was unable to find any documentation on what this figure means or why it may be an issue. It looked like there might have been some explanatory text in the GUI, but it was cut off in the middle of an otherwise readable sentence.

I'm running the 1.29 firmware.

Final Solution: I found a solution here (http://www.multirotorforums.com/showthread.php?3618-UPDATE-Toilet-bowl-in-NZ-after-Firmware-5.06-release/page2) (Thank you 139 jockey!) In short, the GPS Unit heading position should be rotated ~35 clockwise from the heading position of the Naza FC. This will stop the "Toilet Bowl" effect. This solution was posted in relation to the TB effect showing up after a firmware upgrade to the WKM. Apparently the NAZA inherited it. In anycase I just made a rough adjustment and immediately the toilet bowl effect vanished. It needs a bit of fine tuning as the quad now very slowly slides around a two foot box while maintaining altitude. I am going to consider this a fix.

12th March 2013, 12:55 AM
It doesn't know where true north is, only magnetic north. If DJI were on the ball they could have easily built in automatic declination adjustment using a compressed database (since the Naza knows where it is anyway it'd simply need to look up the areas declination in its database, job done).

The GPS course however works on true north... The difference between the two is declination. Sometimes people find it necessary to adjust for declination in order to get rid of toilet bowl effect.

I have found that when my quad flies straight with forward stick, there is no TBE. When it doesn't, there is some TBE. I suspect the misalignment causes the TBE. Variations in motors, escs, and props may cause the misalignment between what the naza commands as 'straight' vs. what IS straight. Still puzzling this through, though.

16th March 2013, 06:10 PM
As you notice the Dji Gps doesnt have any filtering on the cable so if you have issues try a ferrite ring/clip on.Keep it as far away as possible from the Vtx.
Also just be patient until it gets a lock (Solid Green).
Try turning on the quad 1st and then vtx after a lock.
The other alternative is to put a filter on the Vtx.
Its not just the Dji gps, they all have a little difficulty with noise, just depends on the seperation which is tough on a quad type vehicle.
I usually just put up with it and eventually it will get the sats on a quad, On my Zephyr/planes its not an issue as the gps is on the opposite wing.
My buddy has been having issues and moving the Gps 3 inches away made a difference.

Happy St. Patrick's day! After getting a few PMs on the OSD I'm developing, I figured it wasn't too off topic to post a link in here. I've built an OSD/data link (can also send info to a laptop) that displays a bunch of information from the Naza, so you don't need a separate GPS and a bunch of external equipment.

The main thread is over at RCGroups (http://www.rcgroups.com/forums/showthread.php?t=1841246), but in summary, you can do:

Flight mode, GPS lat/long, artificial horizon, speed, altitude, distance to home, direction to home, voltage/current (with external sensor), and a few other cool things. It should be available by the end of March. It speaks MAVLink (http://qgroundcontrol.org/mavlink/start), so it can be interfaced with anything that can read MAVLink packets.

Unloaded I'm seeing 15.4 every time and the battery is taking 1300mah to recharge. I have calibrated the voltage monitor in setup assistant.
2. About every other power-up my aileron channel is significantly left of center. Cycling power off then on fixes it but I'm curious why it keeps happening. I have calibrated the tx but whenever I plug into the setup assistant it is left of center again.
Thanks again in advance...

It will not continue to fly in a forward direction. It almost acts like its trying to stop the forward movement. There are times while in forward flight, in manual mode, that it will fight the forward flight and I have to give more forward stick to keep moving forward. It fly great in every other mode, assist, GPS, heading lock, home lock and return to launch. The cg is perfect and the dimensions for the GPS placement are good. I have tried adjusting the gain for the pitch up and down, they are at p=170, r=140, y=140, v=150 and 150 for both atti, with no change. I tried moving the GPS module to a different place with no improvement. I did do the calibration for the compass and for the sticks. I'm at a loss and do not know what to try next short of putting NAZA on another frame and seeing if it responds the same way. Any suggestions would be appreciated.

Are you sure its in Manual? Sound like Att mode is on and that will try and fight you.
Gps does not have anything to do with Manual as far as I know. Light on the VU should be off in manual mode.
As far as the voltage in the above post I found the voltage monitor to be unreliable and lowered mine to its lowest setting and keep an eye on the time flown.

Im absolutely sure it's in manual mode. I've had this problem since I move to the QAV500 frame. I figure I have done some thing wrong as it was fine on the home made quad it was on.

Could it be that its not a true X? Only other thing I can think of would be cg, it does have an effect, even if the unit corrects for most of it, moving the weight forward may help.

When you say it doesn't fly forward, are
You saying it does act like its in atti and snaps back or are you saying it drifts back over a certain period of time. If its the later try lowering your gains and see it that holds its attitude for longer.

I am new Naza GPS pilot as well, have it installed on a DJI Flame Wheel F450 frame. Flew my first FPV flights yesterday and had a great time, all went perfectly. Today it was much windier but in the evening I decided to give it a shot for one flight. Winds were at 10 mph gusting to 17. I took off an immediately found I had a tough time making any headway into the wind. At the same time my camera started to point down, which was odd because I don't have pan and tilt. I then realized that the camera was loose in its mount! I watched as it slowly tilted until it was pointing straight down. I hit the switch to activate failsafe, and it turned around, flew back, and landed barely a foot from where I had taken off. Whew! Failsafe saved the day. I had tested it successfully yesterday but this was the first time I actually needed it!

Its more like it snaps back as if it was in att mode but it will continue untill its at almost a 45 degree angle at which point I will stop it. Yes it does kinda climb over time as I fly forward. It looks like it would flip over backwards if I let it. If i get moving in forward flight in manual mode and let go of the controls it will it will not continue to fly forward, it will rare up. I have tried the gain all the way down to 100 and up to 180 with no change. Its really strange. It acts as if it is using the att mode but its not. I have several other controlers and have never had on act like this. I think Im going to move it to another frame and see what it does.

Hey guys, quick question here.

What's the fastest way to regain stickcontrol when naza enters RTH?

Switch to manual

I just flick the flight mode switch to manual and right back to gps atti as fast as I can. No need to sit in manual for any length of time.

You can just switch to ati no need for manual.

Ok here's an odd one.. Quad (discovery) flies perfect. It has been updated to the latests naza /w GPS software and has been balanced. My only nodes I have configured are GPS, ATT, and rth as I haven't setup a mix for manual yet. When in any of these modes the craft flies and behaves as it should as long as I have had good satellite lock.

My issue that I have been scratching my head on are when I switch from ATt to GPS about 3-4 out of ten times I switch modes something really weird happens. Elevator will switch to aileron and aileron to elevator in other words when this happens if I push forward or backwards on the right stick the craft will go left and right while moving right stick left and right will cause the craft to move forward and backwards...

To fix this I have to change between ATT and GPS and vice versa and it finally in unconfuses itself and starts behaving correctly again.. Now that I know what is happening and how to get out of that funky state I'm ok but when that first started happening it was a little disheartening when flying fpv away from me behind trees and video signal started going eeek. Now I just want to stop it from happening.

Any thought or anyone else seen this before? Other than this everything works even failsafe.Thanks!

Your switching into course lock by the sounds of it. The 3-4 times out of ten is when your facing sideways to your course lock / home lock and therefore the controls switch to forward is forward relative to the course lock, if your facing 90 degrees off that course then forward will be alerion and alerion will be forward. Are you sure it switches to atti, just check your LED when you change.

You hit the nail on the head. I had completely forgotten I had configured that (its turned off now in the SW) Thanks!
