Hello, can anyone suggest me a three motor setup for a vtol cargo plane ? The plane should carry 3 kg extra payload, so let's assume 7 kg as the total weight, the plane should be a pusher with the rear motor which can be tilted down. The flight time should be exceptionally large like nearly 5 hours ( multi rotor only needed for take off and landing. Can anyone suggest a realistic setup of batteries , esc and motor?
.

If a pusher rear motor is tilted down, will it not nose down and dive?
Not been able to visualise what you have in mind

Nope

The centroid of the triangle formed by the three motors should be at the cg of the plane, if that's correct then the plane would be stable.
