sorry for the confusion;

a higher KV motor (lower turn) has a lower internal resistance than a lower KV (higher turn)

and yes, you are right; the internal resistance of a lower turn (less length of wire with a larger diameter) has a lower internal resistance. That's why it can take more current.

Like i said; it simple takes a larger current burst to spin up a high kv motor, than a low kv motor. gearing would compensate the difference in gearing at the same inertia/speed. but bottom line is that the startup burst will be higher of a higher KV motor.

But that's not all;

One of the reasons why these motors heat up is because they are less ideal for partial load; this seems to be due to eddy currents that disturb the movement of the magnet. with thin sliced magnets (segmented or sintered) the eddy currents on partial load are remarkable lower, and makes it more ideal for partial load. magnetism is a weird thing.

it also takes an ideal gearing per wind of motor to get
into its own sweet-spot (read the story in BrianG's signature ' is my setup too hot ' this would illustrate why you can't simple say 'geared for the same speed with a different KV'
