Servo size tilting motor

HI! I wonder what size the tilting servo should have, if tilting a motor with about 19-21 inch prop?

Maybe try to contact and see if they stock and provide you an appropriate size one.

Having said that, seems like your aircraft is going to be big enough that a 4+1 QuadPlane configuration might be a better option instead of a tilt rotor; less complication not introducing another possible link of failure.

Good luck.

I was also thinking about 4+1 quad plane as more reliable,with less possible failures.
I have visit foxtech site and the vtols with tilting motors, they have “13” props with 28kg Servo.
So tilting a 19-21 inch prop maybe make big stresses at the tilting servo,atleast over time
