The RV15 has a 15 turn motor limit, what this means is that you can use any ,DC Brushed 540 size motor, as long as the number of turns on that motor are equal to or higher than 15.

The RV15 is the perfect speed controller for anybody wanting to upgrade their old stock motor Speed Controller for a no nonsense 15 turn limit reversible electronic Speed Control allowing you to run any motor up to and including a 15 turn modified motor.

The RV15 is the next in line in the Viper range of Speed Controls after the Eco20, which means it has all the same amazing features that you get on the rest of the Viper range and on other, more expensive Speed Controls! Features such as adjustable brakes, adjustable reverse functions and a built in failsafe are standard on this Speed Control.
