Electrical VTOL engineering, motor RPM vs weight loads,

[Davebjones1292]

TL;DR Summary

building a personal VTOL craft

choosing the right motors, the RPMs and weight/load capabilities of the motor/ rotors, combined abilities of electric motors working in tandem, choosing the correct rotors for lift m/ weight ratios, or designing your own?, should one add a small gas powered generator to assist in stable electric power while in flight rather than relying solely on stored NRG contained in batteries/>weight

That will increase the weight and maybe extend the range. Just how you should do that will depend on your unspecified mass and energy budget, and that will not be known until more critical decisions have been made, and the prototype has undertaken some test flights.

I believe you are getting ahead of yourself, extending the design and increasing the mass, at this early stage. There are more fundamental choices that must be made first.
