The RS1 was built specifically to beat the current most powerful BEC powered servo on the market, the Futaba A700! Not only is the RS1 more powerful, but its faster, more efficient, has a more durable geartrain, and is more affordable! The RS1 is built with highest quality parts, designed for the power and speed demands of competition level RC's. One of the most notable features of our RS1 servo is the 5 gear 4 pole gear train design that has been proven to be insanely strong! With the reduction of the 5 gears, durability and precision have been greatly increased over the standard 4 gear design. The RS1 steering is capable of full 180 degree rotation so be sure to set your end points to prevent possible damage to your rc or servo!
