Hello,

I Have a problem with DJi F550 with Naza V2, Zenmuse h3-3d and Dt7 & DR16 system.

When I connect battery on Dji f550, everything is good. I fly about 2 minutes and landed. Disconnected battery from power.
After 5 minutes I connect battery again, and LED module constantly blinking red light.
I disconnect battery and connect it again, but problem shows again. I reconnect battery several time and
on 3rd connect LED blinking ok (good), but gimbal won't start, I disconnect battery, and connect again, then LED
again blinking bad (constantly red). After 10 times of disconnecting and connecting battery to power of Dji F550,
LED blinking ok and I will go to fly. F550 fly good after that.

When problems shows up again (after about 10 -15 flights) I connect LED module via USB to Naza Assistant and Assistant show Error 29 (Motors Start failure caused by TV stick(s) mid point error to big...

I calibrated sticks and do it like manual says, but after some time problems come back.

Can anybody know what the problem is and how to fix it?

Best regards

Have you tried using the RC Assistant to calibrate?

Please also try RC calibration without PC

Thx DJI-Dboy.
I will try calibration without PC.

I noticed that the problem with error 29 disappear when turn off all equipment, and turn on again. I mean when changing battery I don't turn of RC station. Station is online, and DJi f550 is powered off, and problem is manifest in some time.

When I turn of Dji f550 and RC station and camera, and power on that all equipment after 10 sec, I think that the problem disappears.

We will test some time that this really works.

I have a client that have the same problem, we have tested RC calibration and the problem still happening. It was working ok but now after warming it start to show the blinking red. What else can be?

When problem appears try to turn off all, wait 10 seconds, and turn on all.
When I said turn off all, I mean that turn off RC station, power off F550, power off camera.

Some user said that the problem is in RC station, someone said that is Naza...

You can try with new RC station, and if is not problem in station, you switch Naza with new one.
