Hello,
Would anyone be able to help me out with this one?
This occurred in one of our flights where we conducted a transition from Q_Loiter to Cruise. Started at 86m but then the quadplane gained 40m before sharply descending.
Thanks,
Kelvin
You might be better served changing the category to VTOL Plane. In the meantime, @GregCovey might be able to chime in.
Good luck.
It looks like the Quadplane is doing exactly what you told it to do. Your airspeed min setting is 20 m/s, which is where the transition completed.
ARSPD_FBW_MAX,33
ARSPD_FBW_MIN,20
You need to let go of the sticks before CRUISE/FBWB modes start controlling the plane. Here is your stick input to the flight controller below. I would read about the CRUISE and FBWB modes in the WiKi.
Thanks very much for your input 
much appreciated!
Kelvin
