Tekin's RX8 GEN3 brings bigger power handling capabilities and increased reliability to 1/8 Scale Racing. The RX8 platform has proven itself to handle the rigors of racing, while providing professional features including a programmable High Voltage BEC, Data Logging Capabilities, Timing Profiles, Voltage Cutoffs for LiPos, HotWire 3.0 Bluetooth Connectivity and more. Utilizing Tekin's D2 Dual Drive Mode Technology, the RX8 runs both Sensored and Sensorless motor drives seamlessly, giving you the best of both worlds. The small footprint makes install on any chassis easy with the option of mounting with included hardware for extra security. Combo the RX8 GEN3 with a Tekin T8 Brushless Motor for 1/8 Scale Buggies and Truggies or a Pro4HD for 4WD Short Course domination!
