Example, 1200 KV and 2000 KV motors of the same size.. Powering a Monster Truck...

They both have the same power output.. with the lower KV you have to gear higher and use more voltage, and with the higher KV you'd have to gear lower and use less voltage.

I prefer to use lower KV and higher voltage & less RPMS.. but there is a limit..

Lower KV motors can't take as much amps as the higher KV.. the Lower KV relies more on Voltage.. whereas the Higher KV motors relies on Current. know what I mean?

Hi Aqwut,

How about a KB45 10xl in an E Revo?

Let's gear it 20/40 using mod 1 gears, then put in on 6S with a MMM ESC.

How do you think this setup will do, according to your experience with the KB45?

Geared for 44mph according to BG's speed calculator, and spins up to 26,640 rpms.

Also, Where can I find a heatsink/fan for this beast of a motor?
