Arming NAZA

[Av8Chuck]

I had an early NAZA on a Hexacopter and sold it, I'd like to give it another try but I'm having trouble getting the new NAZA to arm. I didn't have any problems arming with the first NAZA and this is the exact same Hexa, ESC's, and motors.

I don't think this is a NAZA problem but I'm not sure, when I hook it up to the computer everything seems to check out just fine but when I plug in a battery the ESC's beep and the NAZA goes through the startup lights and all of that seems to work OK but the ESC's just continues to slowly chirp.

I'm guessing it might have something to do with programing the ESC's but as you know you have to cut the red wire so I don't have any way to test it.

Any suggestions on how to trouble shoot and solve this would be appreciated.

You might want to say what make the ESC's are, what your Multirotor is and maybe your radio type....

the continuous chirp means the esc's never saw a radio signal or the throttle isn't all the way down. when your in naza assistant looking at tx cali tab, does the throttle move all the way on the sliders. i've heard of some people having to increase the throttle endpoints to make the throttle go to the bottom. if any trim is added to the throttle stick that can do a similar thing.

Sorry, the ESC's are RCTimer 30A, motors are Avrotto 2814, Futaba 10CH with S-Bus Rx.

Thanks Kloner, all the controls appear to be correct in the GUI. I'll check my trims and end points again.

and for future reference, don't actually cut the red wire, just use a straight pin of fine point knife blade to release the tang on the pin in the connector and slide the pin out, fold back, and cover with heat shrink.
that makes checking esc settings later on much easier.

I checked the settings in the Tx and the Assistant and everything seems to work as it should. I have a three position switch set for GPS, ATT, and Man, they all turn blue when the switch is set to the corresponding mode.

It goes through the status routine and everything seems to work, I get a constant yellow flash when set to Att and it stops when switched to Man. It just won't arm.

I get an error telling me to contact DJI support for a valid serial number. How do I do that?

Just in case anyone else is following this.

Ok, I tried changing the end points for the throttle and that didn't work. Although all the control calibrations seemed correct I decided to try a normal six channel receiver rather than the SBUS, everything calibrated as it should but still no arming. So I went through the assistant software step-by-step, I chose Hexa-rotor V and after my last experience with my NAZA I had chosen "low Motor Idle Speed" so I changed it from Low to Recommend, chose Intelligent cut off, setup Channel five to a three position switch and it hit the GPS, A and M and checked my calibration, everything to this point worked great. I set the "Intelligent Orientation Control" to channel six with another three position switch and it hit right on for Home Lock, Coarse Lock and off. Gimbal I don't care about and I don't think Voltage Monitoring has any effect on arming so I left that alone for the moment.

Wrote the fie, unplugged the USB, cycled the power and tried to arm it in Manual, nothing, tried in Attitude mode and three motors armed and three seconds later they shut off. So after thinking about it for a second I plugged it back into the computer and changed the only thing that was different from my first attempt, I changed the Idle speed to the speed between Low and Recommend and tried it again this time it armed fine in all flight modes. However it still won't arm if the Idle Speed is set to Low??

I also haven't tried to use the SBUS receiver again, I don't really care which Rx I use. Don't know if this is a bug but it seems to be working just fine now although I have not tried to calibrate GPS or Failsafe or anything.

Just thought you might like to know in case you ever run across something like this again. Of coarse I still have that stupid serial number error.

Is there a simple, easy to understand explanation of how to calibrate the GPS, Home and Coarse Lock? The DJI manual is about the worst manual I've read. Is it too much to ask that they get a copywriter to clean it up so that it is correct and makes sense?

The calibration of the compass in the GPS is easy. Move the mode switch from manual to gps and back 10 times, wait the led will stay on solid, rotate the craft around the Z axis until the light changes, the raise it up and rotate around the X axis until the led flashes and then goes off. You are done. I not sure what you mean about Home and Coarse Lock. Once you get the 4 green flashes in the start up sequence, the craft has registered the home position and direction that it is pointed. After that it is just a matter of selecting which of the IOC modes you want to fly in.

 

[Av8Chuck]

Thanks Ed, and everyone else for that matter.

Everything is working well on the bench without props, hopefully I'll fly it tomorrow. The GPS calibration was very easy, thanks.

Is anyone flying a NAZA with a Futaba 10CHG Tx? If so how do you setup fail safe? It seems easy enough to replace Manual mode with Failsafe on a three position switch but I'm not sure i want to give up manual mode.

Does Coarse Lock make single pilot aerial photography easier or do you find you just use Manual or Atti?

Despite the manual it looks like the NAZA has improved quite a bit from when they were first released.
