Describe the bug My plane is skylark, as shown below.

it's a classical plane, which has aileron, elevator and rudder.

My FC is Pixhawk 4 mini, which has no AUX-output. after flash the firmware and setup all configuration, I choose the vehicle type "Standard plane",

then reboot the vehicle. no motor and servos has response, the ESC keep buzzing slowly which indicate that no PWM signal was fed into it. and ailerons also keep frozen when I roll the plane under 'stabilize mode'.

Then I try the Pixhawk 4, all PWM wires are connect to the I\O output, the phenomenon was same, ESC still detected no signal, servos frozen. Then I change the wires to FMU output, the ESC buzzing quickly, which indicate the throttle was too high, but in fact, the throttle stick of RC was at bottom.

After I change the vehicle type to 'Bormatec Maja' , ESC and servos works fine, which means the ESC and servos works well. and 'Plane V-Tail' also works well in another plane, which means the Flight Controller works well.

So, I think it is a bug.
