'QuadPlane' We have a big problem.

There was a big problem with our plane.
First, we put the QuadPlane firmware on pixhawk1.
Second, the parameter of Q_ENABLE was set to 1.
There’s a big problem here.
Four quadcopter motors and no fixed-wing motor.
There is no pwm signal for each channel on the pixhawk.
What’s wrong with you?
