Radiolink R9DS RC Receiver 10 Channels 2.4GHz

A ten-channel receiver with range and telemetry

The Radiolink R9DS is a multi-channel 2.4 GHz RC receiver for drones, airplanes and cars. It offers ten channels, and the maker says you can operate your model smoothly from up to 3.4 km away.

Advanced DSSS and FHSS technologies keep the signal stable and uninterrupted. The receiver supports both SBUS and PWM outputs, so you can connect it to a flight controller with a single wire or to servos directly.

What to know

Control resolution is 4096 steps with 0.25 microseconds per section, which gives smooth, precise servo movement. The receiver can send back real-time information such as signal strength, receiver voltage, speed and GPS data to a compatible transmitter, and it weighs only 10 g.

It works with Radiolink transmitters that support the same protocol, so check compatibility before you buy. When installing, mount the antennas clear of carbon fibre and wiring, bind the receiver, set failsafe and test every channel with the propellers removed.

Who it suits

Pilots and drivers with a Radiolink radio who want a long-range, telemetry-capable receiver with a choice of outputs.

Wiring SBUS or PWM

If your flight controller accepts SBUS, one wire carries all channels and keeps the wiring neat. For a simple aircraft, use the PWM outputs to plug servos and an ESC directly into the receiver. Keep both antennas out in clear air, at different angles, and away from carbon fibre and power wiring, and set failsafe before you fly. Because the receiver can report signal strength and receiver voltage, set the low-signal and low-voltage alarms on your transmitter so you get an early warning instead of finding out by losing the model.
