Hello, I am making a quadplane with two front motors for forward thrust but they aren’t working when i flip the transition switch also ailerons servos are also not working. Also during the Multirotor mode 3 out of 4 motors starts when i ramp up the throttle but not the fourth one.

Update for the above problem. Front Transition works fine but the back transition is not working. When in toggle the switch for back transition the forward motors ramps up a little bit then slows down and everything stops. Please help me out.

Maybe try increasing VT\_B\_TRANS\_DUR to maybe 6 or 8 seconds?

Good luck.
