Well, for the flying model, Printed Motors is probably out.
These are mostly old-tech, and alnico, thus quite heavy. I
think what you need are either ironless rotor brush motors with
rare-earth magnets, or some low-inertia brushless motors.
Depending on the size needed, Yaskawa is good for larger ones,
and Maxon makes some great small ones.
