Yep channels are fine.
Spektrum is TAER (Throttle = 1, Aileron = 2, Elevator = 3, and Rudder = 4)
The UMX and parkzone micro stuff is fine. Just one plane causes violent shaking of the servos with certain receivers.
It could be a BEC issue, Servo issue, REC, module, or even minor timing / setting issue.
Just curious if folks have used taranis with orangeRX module with certain settings for DSM2.
