Help!No throttle out in VTOL qstabilize modle

When I use a Matek F405 wing board with plane 4.0 firmware in a tailsiter flywing plane,if I switch to QStabilize ,there is no throttle out either on motors or mp,but the aileron servors is right,what’s happened?

btw.Stabilize / FBWA / Manual is OK
servo1_function=74
servo2_function=73
Q_enable=1
arm_check=0

I need you help,thanks!

That is a bug with arming,i know.

Hi Seal, did you find out which parameter was stopping the throttle in Qstabilize?
