The Tempo11 has an 11 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 11.

The Tempo11is perfect for anybody wanting to upgrade their old Speed Controller for a no nonsense 11 turn limit forwards only electronic Speed Control allowing you to run any motor up to and including a 11 turn modified motor.

The Tempo11 is the second in line in the Viper range of forwards only Speed Controls and big brother to the Tempo15, which means it has all the same amazing features that you get on the Tempo15 and on other, more expensive Speed Controls! Features such as adjustable brakes, adjustable acceleration and a built in failsafe are standard on this Speed Control.
