No Superior Designs RS1 Monster Torque High Voltage Brushless Servo. Designed specifically to be one of the strongest, fastest, and most durable BEC powered servo on the market! The RS1 is built using top quality materials and designed for the power and speed needed for today's competition level. One of the most notable features of the RS1 servo is the industry leading 5-gear and 4-pole design. With the reduction of the 5-gears, durability and precision have been dramatically increased over the standard 4-gear design! Get this monster performing BEC powered servo and experience the power of the RS1!

  • Requires a Castle 10 amp BEC or better. Low amp output ESC will not power this monster servo sufficiently and may not function properly.
  • For use with Spektrum receivers it is recommended to use a receiver bypass harness. Some Spektrum receivers cannot handle higher amp draw and will fail and can cause damage to the servo.
