I have a tri setup, just downloaded the latest arducopter 3.2 code. However, the tail servo is not moving at all, ch7out is stuck @ 1517 (monitored in mission planner), which is roughly neutral. This is in mode Acro and stabilise. Additionally, I would expect a nudge when armed, but this does not happen either. I just upgraded the firmware yesterday after a successful autotune with 3.1.5
I can not see anything specific in the parameter list related to yaw, except some new parameters which has been documented.
Any help is greatly appreciated.
