3DR AdruCopter Quad-C Frame Kit & Electronics questions

Hello,

I sent a message to 3DR support about a week ago and I figured I should just post some questions I had here. 

I have this kit on the way today, with the 850kv motors and I am wondering about some things.

Radio calibration - Pitch and roll linked in some strange way.

Hi.I have a problem when I'm trying to do a Radio Calibration on my tricopter. Have connected my receiver and the APM, and when I give either roll or pitch input both the pitch and roll bar in Mission Planner move simultanious. It almost seems like p

quadcopter yaw at full throttle after simonk flash

I just flashed my ESCs with sinonk.  Since then when applying generous throttle the quad does not maintain heading and there is significant yaw.  Prior to flashing there was no yaw at full throttle.  Is this typical?  What changes to PID would addres

Crossed controls in simple mode - responds as expected in stabilize mode

I have an APM equipped quad in an X configuration. When I fly in stabilize "only" mode all controls respond in a proper way, switching to simple stabilize in "tail in nose out" orientation and pushing the right stick forward makes the craft fly to th

Thanks for all the help!

This afternoon I flew my Hexacopter for a total of about 40 minutes and everything seemed to work okay!

I started off loading the new version of MP, then restarted the computer and loaded the firmware.  It took a couple of tries but I finally got it t

Readiness for 3.0 ? (APM2.5 OCTO QUAD)

Hello,

I just finished my conversion from quad to OCTO quad. I installed 10" 4,7 props on top and 11" 4,7 props on bottom. I get a hover at full lbattery at 55% throttle for an AUW of 3.9 Kg (almost 8 pounds).

Among which 2 4S 4500 batteries (almost 1K

What log values to look at for vibration?

I have a quad w/ 2.91 -- the APM is mounted using servo tape. All of my motors have insulated mounts. Is there a way to tell if I'm getting bad/any vibration to the APM?

And if so, what is the preferred mounting method of the APM to the frame?

Loading Firmware

I have loaded the V2.9.1 Arducopter firmware but I get the following message:

Is this normal?  I have tried to load the firmware several time but I get the same message.

Hexacopter motors go to full speed arbitrarily

Has anyone had a situation where their Ardrupilot based Quad/Hexacopter would be flying normally and then arbitrarily the motors go to full speed?

I am continuing to set up my “RTF” 3DR Hexacopter and have had this type of thing happen several times.

Activating GPS?

Hello all,

I am building an Arducopter 2.5 kit from DIYDrones.  When I first purchased the kit, I ordered the MediaTek GPS unit.  When I plugged it in to the APM, the red light came on only very weakly and I never got a signal according to Mission Pla
