Coming from Tekin is their new RS Pro 1-S brushless speed controller for 1S LiPo applications. The built-in advanced booster circuit provides consistent servo power throughout the entire run with no performance fade and the extremely low on-resistance delivers more power to the motor which translates to faster lap times. HotWire compatibility, a compact size and URL high-flex wire round out the package, that large builds on the recently introduced RS Pro.
