Turn the higher the speed

To work out the RMP of a motor you times it buy the voltage of your battery. Range of brushless motors and speed controllers: http://www.1 (3s lipo) = 43,290 rpm To summarize a higher kv motor will be faster but have less torque, in trucks this covers stadium trucks, short course trucks, truggies and monster trucks its much better to run a lower kv motor on a higher voltage than a higher kv motor on a lower voltage. 3900kv x 7.Saying that the 3900KV would be faster in a truck on 3s and as there's more torque it would handle it better. With the old electric motors (brushed motors) they were rated in turns e. 21t, 17t, 15t and so on the lower the turn the higher the speed but the lower the torque. To get the heat down you would have to add a larger spur gear and a smaller pinion gear. So for instance a 5700KV motor will be faster than a 3900kv motor in 1/10 scale but the 3900kv motor could go in a truck where as the 5700kv would get very hot as there's not much torque.4 (2s lipo) = 28,860 rpm 5700kv x 7.g.4 (2s lipo) = 42,180 rpm 3900kv x 11.co. So what is it and is it better ? Brushless basically says what it is, a motor with no brushes inside this means minimal maintenance is needed, so turn it on and away you go. To understand KV is like understanding the turns on a motor the higer the KV the faster it will be, but the less torque it will have.. The KV ratings above are based on 1/10 scale motors, the same rules apply for all other scales the only changes will be the KV ratings on the motors.4 (2s lipo) = 42,180 rpm In a truck everything changes as you also need to torque as well as speed on paper the 5700kv motor would be faster but it would get very hot as the torque wouldn't be there. 5700KV x 7. On a 3s lipo battery China Magnetic latching relays Company you would destroy the motor with the drag on it. The Term 'Brushless Motors' or 'brushless' is being passed around in the rc world. In brushless you get turns mostly on the 1/10 scale motors and kv ratings on all the motors, if it is not displayed on the motor the manufacturer will display the kv rating in the instructions.
