which motor is faster
 

which motor out of the below kv would be the fastest,

if the kv doesnt exist on a motor do not worry they are just examples,


8000kv

4400kv

3900kv

2300kv

also if i were to put these in my 18th car what difference would i notice from each of the kv's

and which would draw the most amps,

thanks for any replies,

The highest number. The KV stands for K(1000)RPM per V(volt)

So an 8000KV motor and a 10V battery (for example) would mean that the motor would theoretically run at 80000RPM (without timing, etc)

I hope that's clear?!!?!:thumbsup:

Obviously the faster the motor the faster the car, the less the runtime and the more current it will draw.

hope this helps

















hope this helps info taken from else were

thanks all, with the above info and my research on the web i got my info needed, thanks again, :thumbsup:

that chart doesnt seem right,i thought 8.5 turn was 4000kv
also a high kv motor maybe faster but surely its about usable
speed,a high kv motor is faster yes but in a straight line
and powers up with a bang
in 1\18th scale i found 3900kv the most usable as torque is
better and smoother throughout

it varies, I have 6.5t motors from 5150kv to 7400kv, and a 10.5t which only gives away 200kv to an 8.5t.......
It varies dependant on manufacturer.
