SD-4 "SILVER" Speed Controller

SD-4 All Silver Features:

This controller is basically a SD-4 with all Silver Electronics, The Wiper Arm and Trigger Braket, The Full Punch Tab and The Brake Tab. Silver is considered to be a better CONDUCTOR than Copper

The secret is in the ability to adjust the sensitivity to the torque of the car. Ever run a car which responded better near the end of the trigger pull, or vice versa, it falls on it's face at full throttle. Now, with this controller you can give that arm the juice where it needs it. You can actually optimize the power and torque of the individual cars now. Try it and you won't deny it. It's the next generation in controller adjustability.

This one is built with a coast which is switchable. If you don't want to use it, turn it off with the flip of a switch. Turn the switch on and a potentiometer will help you adjust the amount of coast for the track you're on, all this independent of the six adjustable bands that replace the traditional resistor. Scott, you've outdone yourself this time. 325.00 Plus Shipping
