Hi,
My APM2.0 with ArduPlane 2.68 does couple of things that I cannot believe is quite right:
- When powering up the plane without the transmitter on, the receiver (TFR4) does not output any signal. The APM take the elevator and rudder servos (maybe aileron too, when I have the wings on the plane) go full deflection to one side and threaten to burn out the servos if I leave them there. Did others observe the same? Would center position not be a better default value?
- Recently, my APM often (always?) will not calibrate its gyros, will not respond to R/C and will generally not do anything at all until after I have connected to it from Mission Planner the first time. Did others observe the same?
Regards
Soren

OK... Well when I do tuning, testing and development at my desk at home, I can't have a tx on all the time. My expectation based on other systems etc. is servo controls centered, throttle at zero. It is not done that way in APM?

Wrt #1, even with Tx on, the rudder servo slams to full left.

The first rule of RC is ALWAYS, ALWAYS Turn on the transmitter FIRST, then the receiver , then the Quad or plane. when you have finished and want to close everything down ALWAY turn off the quad or plane , then the receiver then the transmitter LAST
Otherwise the receiver does not know what to send out to the servos or the APM as you have found out.... it is dangerous.
I have seen planes and quads go to full power when this happens, you dont want to go there!!.
