RS1 Monster Torque Servo

Our RS1 was built specifically to be the strongest, fastest, and most durable Bec powered servo on the market! We built the alpha of all 8.4v servos available... Yes, stronger than the Futaba A700, Protek 1k, and all other competitors attempts! Not only is the RS1 more powerful, it's faster, more power efficient (7.5 amp peak draw), has a more durable geartrain, and is more affordable! The RS1 is built with the highest quality parts, designed for the power and speed demands of competition level Rc. One of the most notable features of our RS1 servo is our industry leading 5 gear 4 pole gear train design. With the reduction of the 5 gears, durability and precision have been greatly increased over the standard 4 gear design. If you're looking for the highest performing bec powered servo available, you've found it!

☆Requires a Castle 10 amp Bec or better. Low amp output esc's won't power this monster servo sufficiently and may not function properly.
