With an integral heat-sink, these servos are designed for the demands of competition racing, keeping the motor cool even when the outside temperature is hot and the servo is being overused. With a heavy duty rubber-sealed waterproof case and high-strength horn set, this servo is perfect for high-performance R/C car applications. And the output splines are compatible with aftermarket 25 tooth Futaba horns.
The servo will automatically learn the user's transmitter pulse timings and lock into the signal every time. The servo also includes a signal buffer in the CPU with fail-safe functionality. The motor is wound with 2PEW thin coated wire for better electrical conductivity and is able to withstand over 120° C without degradation.
The servo comes with an accessory package and the universal JR/Hitec "S" Connector which is physically and electrically compatible with all major receiver brands sold worldwide. Follow the wiring diagram below. If you hook the servo up incorrectly nothing bad will happen - just flip the S connector around and the servo will work correctly.
