FrSky HV5101 is a digital servo operating in F.Port2 / SBUS and PWM modes. It can supply up to 8.4 V and the Hall sensor ensures accuracy. The whole body is made of aluminum with metal gears and two bearings. The servo is telemetric, adjustable and has updatable firmware.
Tandem series receivers provide connection to the radio on two frequencies, including telemetry. This makes transmission less prone to connection failures while providing greater range.
