RADIOMASTER R86C 2.4GHz 8CH D8/D16 RC Receiver Module

A budget receiver for FrSky-style radios

The RadioMaster R86C V2 is a compact 2.4 GHz receiver for RC aircraft, drones and planes. It speaks the D8 and D16 protocols and is compatible with SFHSS, so it fits a wide range of existing transmitters. It offers 6 PWM channels or 8 channels over SBUS.

The frequency range is 2400 to 2483.5 MHz, the range is more than 1 km, a 15 cm antenna, a 45 x 21.2 x 12.7 mm body and a weight of 8 g.

Choosing between PWM and SBUS

PWM gives you one wire per servo or ESC and is straightforward on simple aircraft. SBUS carries all channels on a single wire, which is neater with modern flight controllers. Note the power limit: the receiver accepts 4.5 to 8.4 V, but only 4.5 to 6.6 V when SBUS is in use, so feed it from a regulated 5 V supply if you are unsure.

The receiver is easy to bind with compatible transmitters.

Who should pick it

Modellers with an existing FrSky or SFHSS transmitter who want a low-cost receiver for a plane or small drone. For long-range flying, an ExpressLRS receiver is a better fit.

Setting it up

Binding depends on your transmitter's protocol menu, so follow the procedure for D8, D16 or SFHSS that your radio uses. After binding, set a failsafe so that the throttle drops or the aircraft returns to a safe attitude if the link is lost, and check every channel's direction on the bench. Do a range check with reduced transmitter power before the first real flight, and keep the 15 cm antenna clear of carbon and metal.
