A VTOL tilt motor mount mechanism for Ardupilot or any type aircraft that needs a tiltmotor/tiltrotor. This is going on a front-yaw tricopter. The mount fits on a 10x10mm balsa or aluminium dowel used for tail booms.
I'm using a H-King HK15178B metal gear servo to tilt the motor. Motor can be any 30g -70g type. Prop size = 7"-8" as the propwash will interfere very little with the wing. For larger props you have to adapt the mount. Arm moment is about 28mm and this servo can do 30mm so enough for ample tilting.
