The FX-R reversing speed controller leads the industry in pure rock crawling performance. With its tiny footprint, improved drag brake resolution with lock-down holding power, adjustable reverse type with reverse delay, no reverse or instant reverse, ultra smooth low speed creep and precision throttle and braking response, the FX-R easily gives you the edge over the competition. The FX-R has thousands of possible settings right on-board with Tekin's QuickTune Programming and is capable of extensive tuning and updating when used with Tekin's HotWire PC Interface*. The FX-R can also take on your power needs with 3S Li-Po compatibility when used with 35 turn or higher motors. Install the FX-R and step up to smarter, smaller, faster electronics. And if you have an older FX-R you can download the latest software updates with our HotWire interface.Less
