I wonder if this will cause some parts of the motor to heat up more; since the blade is 1:1 rotations with the motor then driving more torque (power) during certain phases of the cycle will put more watts on certain coils.

It's a cool idea. Human size helicopters would love to avoid all that blade-pitch complexity. :)

Couldn't that be addressed (if a large enough effect to be a problem) by just having the body of the vehicle spin at a low rate, like less that 1Hz. With appropriate sensors this wouldn't be a problem[1]. More to the point, there shouldn't be any need for sustained constant "cyclic" input anyway, in normal maneuvering.

[1] an axially-symmetric imaging system could compensate easily, e.g. a panoramic system.
