Strong and extremely fast narrowband digital standard 79g servo with AC (brushless) motor with titanium/steel gears and output shaft mounted on three ball bearings for use as a rotor balance servo in 500-800 RC helicopters. For perfect cooling even under heavy load, the servo is housed in an aluminum box.
Narrowband servo - neutral 760 µs, repetition rate up to 666 Hz - only for use with compatible gyro systems/flybarless control units as a trim (tail) rotor servo; cannot be connected directly to the output of a common receiver (neutral 1520 µs). Make sure to set the correct type (narrow band) servo on your gyro/control unit.
The servo is not programmable.
Extended supply voltage 4.8-7.4 V (nominal).
25 Tooth/5.92mm Hex Output Shaft.
