Info about motors

[hack73]

Little info I found on the net that will help out when planning on upgrading the motor:

A fast spinning motor (high KV) would use a lower cell count pack that a slow spinning motor (low KV).

In the airplane world, lower KV motors spin larger props

Say a 1000KV motor with a 9x3.8 APC prop on a 3s pack (11.1V) would pull about 13A.
A 2800KV motor spinning a much smaller 6x4 prop on a 2s pack (7.4V) would pull about 13A.

generally a lower kv motor will produce more torque and faster one will produce less. this is why they say the lower kv, say 1000 are good for direct drive, while higher kv, like inrunners are better for geared applications.
