Tilt Quad VTOL with Payload more than 10 kg

Hi, I am planning currently to develop a VTOL airplane with payload 15 kg. The motors that I will be used are the P80 Motors from the T-Motor with CF 30x10.5" Propellers. The idea is to make a tilt mechanism for these motors. But I am not kinda sure, is it possible to do it with 100kgcm servo for each motor? Or does anybody have experience with it?

Thank you!
