Sensored Operation

Technology of today has allowed many great things to be added to Tekin ESC's. Pioneering the world of Boost and Turbo, Tekin has taken these features to the next level in the RS GEN2. Precise control and a wide range of adjustability provide a smooth power band and throttle curve for Boosted setups. We just raised the bar, again.


D2 is Tekin's hybrid sensoreless / sensored drive technology, fusing the reliabiltiy of sensored with the efficiency of sensorless. D2 provides perfect starts and smooth low rpm operation while allowing for dynamic timing adjustments and running efficiency at higher rpms.

RCTVLive RS ESC Review


The RSX speed control defines capability and versatility unlike any other electronic speed control on the market. With high-end components utilized throughout, the RSX takes 1:10th scale competition racing to a new level. Power, control and reliability remain the foundation of this RS-based ESC. Built with a custom high-efficiency aluminum heatsink housing and full onboard programming, the RSX provides the tools for the win!

Armed with features, the RSX was designed for modified racing. The aluminum housing and detachable fan shroud system maximize cooling for extreme racing conditions. Capabilities such as datalogging and HotWire EZ Port communication allow you to unlock the full potential of the RSX with extensive tuning and datalog feedback. The high-voltage BEC puts out the power you need for fast, precise steering servo operation. If you're looking for the ultimate ESC in modified racing, the RSX is there for the job.
