Matt,

I will admit that I limit throttle on my slick to keep it from getting warm and it does work, but apparently not a good idea. The reason limiting throttle does not limit amps (peak amps, not average overall) is due to the way that the esc reduces amps/voltage to the motor by chopping out cycles of the esc.

Also, with regard to prop size. Glow is different than electric. Glow is a constant power situation. If you lower prop size, it spins faster. So if for example, you run up the motor without a prop it will attain an rpm high enough to blow apart the motor. However, electric motors are in a constant rpm mode, which is determined by the KV rating. So no matter the prop size, it spins up to a specific rpm regardless of the power output. So larger props draw more current, and can burn up the motor, and smaller props will draw less current. That means you can actually run up the motor to full throttle without a prop and not damage the motor. It just doesnt draw any current.
