Neu motor rpm speed question for BrianG

Define "better".

If better means "more efficient"; to me it doesn't matter if temps during my informal testing are any guide.

If better means "smoother"; then yes. I daresay almost as smooth as a sensored setup at low speed. Smoother running would also lessen the chance of cogging at really low speeds - and we know that a cogging (effectively stalled) motor pulls LOTS of current.

You don't want to go crazy with this idea though, like putting a 1527/1d (kv=2300) on 6s lipo on a 8th scale buggy, but gear down for 20mph. The motor wouldn't be loaded enough.

What I am trying to say is that I don't like getting a low wind and applying low voltage for low rpm and then gearing up to compensate for lack of speed.
