This speed control has the same power as the Viper Eco20 but has no adjustable settings and an auto set up routine, so no set button, you just plug it in and go!!

THIS IS A FORWARD, BRAKE AND REVERSE ESC.

Ideal for upgrading your standard speedo so that it's waterproofed and can take a higher power motor.

Suitable for all motors down to 20 turns (i.e. 20x3, 21x1, 23x2, 27x2 turn etc etc)

Manufacturer's description follows:

The Auto Sport tuned 20 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.

The Auto Sport tuned 20 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 without the added ease of no difficult setting up!

The Auto Sport tuned 20 uses the new automatic set up software 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 Auto Sport tuned 20 slots in the Viper range of Speed Controls, which means it has all the features that you would expect on a more expensive Speed Control! Features such as a built in failsafe and current limiters are standard on this entry level Speed Control.

TECHNICAL NOTE: This model of Mtroniks ESC is incompatible with a very small number of Carson radios due to the way Carson reacts during start up.  This only affects a small number of radios from some batches.  If you are using a Carson radio we recommend the Carson Dragster ESC instead.
