Tekin - RX8 1/8 Electronic Speed Control

Versatility and longevity, two key features defining the RX8 GEN3. Flash a Drag-Specific firmware update with the HotWire device and software and transform the RX8 GEN3 into the ultimate Drag Racing controller. Access drag-specific settings like full sensored motor drive, timing boost and turbo features, throttle management settings and dominate the strip.

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!

Some settings and features differ between ESC models

On board Data Logging with the HotWire brings you all the info you need to know about your last run! Record a few laps or a pull down the drag strip and review the data on a PC or Android device immediately afterward. Monitor ESC, battery and motor performance so you can get the most out of your system and keep your setup tuned perfectly!
