KOF700-14- Wing electronic pwm MOSFET controller with voltmeter, 14 feet of electronic choke, sensitivity, choke bypass, Pro variabrake with full off and "mush" button. Cool operating, smooth, light weight and compact with long flexible cord from power module to handle, ideal for traveling. Bracket to hang power module on side of track wall. Infinitely adjustable choke with 1/2 foot steps, get exactly the choke level you want. Linear response eliminates the 1-2 volt jump between the last band and full power with conventional controllers. This results in better control near full power. Response is linear at any sensitivity setting, none of the "controller does nothing until the trigger is almost fully pulled" that many standard transistor controllers have. Full on resistance less then with relay. 25 band switch block. New high impact handle.
