Yeah, nice that you mention it;

The eddy currents are responsible for the motor not being too efficient on a partial load. (segmented magnets don't suffer as much as solid magnets (or the three thing 'segments' of a feigao/wanderer/nemesis motor, which is considered a non-segmented magnet).

Like you say;

a heli runs on a rather constant RPM. (CP's at least, and i assume you are talking about CP instead of FP choppers) the pitch of the blades determine the load the motor gets. due to that the RPM vary a bit. Not as much as with cars.

Quite simple; my lehner XL2400 powered maxx felt more agile on 3S than my Lehner 2250 powered savage. Both had about the same rpm. The small motors spin up fast. (noticeable for acceleration)
