my brand new APM2 doesn't seem to arm in any way.
I followed the wiki (uploaded the firmware, calibrated the radio etc) yet I cannot get the "A" LED solid and the motor or servos which are plugged in the output rail do not move.
I have kept the rudder stick on the right for many seconds, tried the same with the other sticks but no way, board is not arming.
I don't think that the output rail is faulty because I have the impression that the PWM signal is sent, servo moves the first time is plugged in and the ESC sound is like the one you get when the receiver is correctly plugged and throttle stick is down.
Thank you very much for your help,
