I just setup my x650F quad with apm 2.6 and having problems with the yaw stick response as well as the apm yaw response too.
What happens is that when I hover it while holding it with my hand and turn the quad left, The copter tends to pitch forward and does the opposite when I turn it to the right.
When I yaw left with my stick, the copter pitches forward and opposite also happens when I give it right input.
pitch and roll response seems to be ok(it fights my hand when I pitch for/rev as well as roll right/left.
I also have the CCW / CW props in the right place and verified with the motor test using the terminal at the Mission planner.
My setup is as follow:
iPeakA HV-40 40A Opto Escs
NTM Prop Drive 28-30S 800KV / 300W Brushless Motor (short shaft version) (USA warehouse)
4s 3300 turnigy 25c
Please Help… This is my first quad with APM. I have setup a Hex with success on this controller before.
