The RadioMaster R84 V2 is a compact and lightweight 2.4 GHz receiver aimed at fixed-wing aircraft and small drones. It offers four PWM outputs and is compatible with D8, D16 and SFHSS signal formats.
At 2 g and 17 x 11 mm, it is one of the smaller receivers you can buy, and it comes with a 6 cm antenna. Control distance is more than 1 km, the frequency range is 2400 to 2483.5 MHz and a power input of 4.5 to 8.4 V.
Four channels cover the essential controls of a basic plane, and the tiny size makes it useful in foam models and micro builds where every gram matters. If you need more than four channels, or SBUS output for a flight controller, choose a larger model such as the R85C or R86C.
Confirm that your transmitter can transmit D8, D16 or SFHSS before you buy.
The receiver is sold as a single unit.
At 2 g the R84 V2 is easy to bury in a foam airframe, but keep the 6 cm antenna out in the clear, away from carbon rods and battery leads. Bind it using your transmitter's D8, D16 or SFHSS procedure, set a failsafe, and test the direction of each control surface before the first flight. Power it from a regulated 4.5 to 8.4 V source. Because the board is so small, secure it with foam tape or a dab of hot glue rather than a heavy mount, and leave a little slack in the servo leads so a hard landing does not pull on the connector.
