Ive been tuning my ardupilot 2.7.1 and imuv2 in for a few weeks now and the following work great:
Fly by wire A
Havent tried auto yet.
PID tuning has been good and fly by wire A flies like it on rails.
Today ive tried FLY BY WIRE B but I get no elevator control. Pushing nose down slows the motor, puliing back speeds it up.
Has anyone experienced this? The throttle control jumpers seem to be wired up correctly as it works in both fly by wire B and RTL (in that the throttle varies etc as ardupilot commands it) but elevator becomes a secondary, less effective throttle control in FLY BY WIRE B.
Any guidance appreciated, things have gone fantastically to date!
