DD270 – The new E.S.P. brake relay significantly improves full brake response for scale and retro type racing. The brake relay is controlled by a tiny switch on our circuit board. When activated the heatsink mounted relay bypasses the brake rheostat and the fuse to give the shortest resistance path and maximum braking. Since the relay does not depend on contact between the trigger and the brass brake post the braking response will not degrade because of arcing built up on the contact surfaces. This means perfect and consistent braking every time. 30 band controller with economy brake rheostat. Optional plug in networks let the racer tune their controller for any car from 1/32 homeset to the fastest G7 motor. E.S.P. brake and Blast relay. Replaces the DD250 model.
