Basically as I understand it, a high kv number equals a low turn motor.

Low turn is for going fast on a track, say like an onroad 1/10 scale touring car.

And vice versa with a high turn/low kv number. They are good for off road vehicles... (more omph at take off, better acceleration, but a lower topspeed)

So for bashing I would recommend a lower kv number,around 27-3000.

For on road racing you're looking for higher numbers.

Be warned though, the higher kv you get the faster the car will go, but it will also be that much more difficult to control...

I'm just starting out in onroad touring car racing and I'm beginning with a 17,5 turn sensored motor.
Once I get the hang of it, I'll most likely get a 13,5 turn and so on....


Hope that helps.

If that's the esc you're getting then look at motor turns not Kv. Sensored motors in general are rated in turns, anyway, Stock or mod racing? Ask your track but most run 17.5 motors for stock and mod is normaly open to any motor. A 13.5 or 10.5 is plenty if you're new to mod buggy.

Talk to the guys at your local track but if your even remotely new to racing you'll likely want to run in the stock class. Mod is not the best place to start racing.

Lower KV can be as fast, 2650KV or 2200KV is what you could use in your EBUGGY... KV is the RPMS a motor turns.. A 17.5 brushless or 12 turn brushed motor is what you would run in a stock 2wd class, My 4x4 slash has a 3800KV motor in it. 55 turn is what you would run in a rock crawler, go down from there.

I would look at 3000kv to 4000kv. Any less will be slow on Nimh or 2s lipo.

If it's the 4 pole motor it really doesn't compare to any "turn rated" motor, apples and oranges really.
