More info

The Autosport20 has a 20 turn sport tuned 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 20.

It is a perfect entry level speed controller for anybody wanting to upgrade their old speed controller for a no nonsense 20 turn limit reversible electronic speed control with the added feature of no difficult setting up!

The Autosport20 uses the new automatic set up software 'Plug n Play' which calibrates itself to your transmitter as you are actually using it!!! There is no set button or difficult set up, you simply plug it in and go! It's as easy as that!

The Autosport20 is a popular choice from the ever popular line of Viper car speed controls, this is due mainly to all the features that are included, such as a built in failsafe, 100% proportional, fine throttle control in both directions, and motor stall protection, which is a feature that cannot be overlooked when getting stuck in the long grass or undergrowth is a definate possibility. Not to forget that the Viper range of speed controllers are all completely 100% waterproof and designd to work in the wet so even the traditional UK weather doesn't have to stop you having fun!
