Is this a new APM? If not, has flown before (or crashed)?
Have you monitored the voltage from the ESC/BEC while this occurs?
Can you monitor the control sticks (like Spektrum)?
With rudder input affecting aileron also, it sounds like your system is coupling them both, mixing... like a flying wing. Perhaps there is a mix command on your transmitter set?
What program/instrument are you using to make the displays provided?
Thanks for your answer.
With no APM and good behavior of the TFR6 and servos, it does imply the APM or connections.
Did the system work well at any time?
Do you have magnification to inspect the connection paths of the circuit board? (not likely but...?)
I have not investigated all parts of the Mission Planner yet.
I think it is a new issue but it is possible that I had not detected before.
The paths seem OK.
You can see the graphics, you only have to check "Tunning" in the "Flight" tab under the map.
I did some more test:
Anyone know what else I can do, before throwing away board?.
Make sure you have the latest ArduPPM firmware for the 328p chip.
Like can I see the present firmware version of ArduPPM?
And to update this firmware I would need other board, isn't it?
Thanks at all for your help this is the spirit of opensource.
John sorry for the off-topic question, but did you write the new apm2encoder firmware http://code.google.com/p/arducopter/wiki/APM2Encoder, that makes turnigy 9x receivers initiate rth when they lose signal.
Yes, the latest APM2 ppm encoder firmware (2.2.68) will set the throttle to fail-safe (900us) if you lose contact/turn of the 9x.
