Higher kv vs. taller gearing

[BrianG]

Feigaos are 2 pole, as are MM motors and LMT motors.

The "35k rule" is basically for the Feigaos as they tend to lose efficiency rapidly over that and simply heat up. Motors like the Neu and LMT are higher quality and seem to run just fine at higher rpms. Usually, I like to stick to max rpms that are around 75% or less than the max rpm rating.
