The RadioMaster R85C is a compact and versatile PWM receiver for RC enthusiasts. It offers reliable signal reception and stable performance, and its small size makes it easy to fit into different models, from planes to small vehicles.
It is compatible with FrSky D8, D16 and Futaba SFHSS, so it works with many existing radios. A built-in temperature-compensated crystal oscillator (TCXO) keeps timing accurate in any environment.
It has 5 PWM channels, a 4.5 to 8.4 V DC power supply, a frequency range of 2400 to 2483.5 MHz and telemetry power of 100 mW (20 dBm). The receiver weighs 5.55 g and measures 31.0 x 18.5 x 13.0 mm. It has five PWM outputs, so plan your wiring for five channels.
Check that your transmitter supports D8, D16 or SFHSS before buying; it will not work with other systems such as ExpressLRS.
Hobbyists with an existing FrSky or SFHSS radio who need a compact PWM receiver for an airplane, glider or vehicle.
Follow your transmitter's binding procedure for D8, D16 or SFHSS, then set the failsafe and check each channel's direction with the propellers off. Keep the antenna away from carbon fibre and from power wires, and run a range test with reduced power before the first flight. Power it from a regulated supply within 4.5 to 8.4 V. With five outputs it suits a typical airplane with a spare channel for flaps, lights or a retract switch, and its built-in TCXO means bind and range stay consistent from a cold morning to a hot afternoon.
