QWhat signal outputs does R8SM support?

A:R8SM supports SBUS and PPM two signals output.

Receiver indicator is RED with all 8 channels output PPM signal.

Receiver indicator is Blue (Purple) with 8 channels output SBUS signal.








QHow to bind R8SM to RadioLink transmitter?


1. Put the transmitter and the receiver close to each other (about 50 centimeters) and power both on.
2. Switch on the transmitter and the LED of R8SM will start flashing slowly.

3. There is a black binding button (ID SET) on the side of receiver. Press the button for more than 1 second and release, the LED will flash quickly, meaning binding process is ongoing.

4. When the LED stops flashing and is always on, binding is complete and there will be a signal tower shown on top of the LCD screen of the transmitter. If not succeed, the LED will keep flashing slowly to notify, repeat the above steps.

Note: If bind to transmitters without screen like T8S or T8FB, the always on LED means binding completed.








Q:How to switch the signal working modes?

A:Short press the binding button (ID SET) twice within 1 second. When the Red indicator is on, signal output is PPM. When the Blue/purple led is on, signal output is SBUS.









Q Why the LED of R8SM keeps flashing slowly?

A: The slow flashing LED means binding doesn’t succeed or the signal gets lost after binding completes.








Q:What is the operating voltage range that R8SM supports?

A:The operating voltage range of R8SM is from 4.8V to 6V.








QWhat transmitters are compatible with R8SM?

A:R8SM is compatible with RadioLink T8S/T8FB/RC6GS V2/RC4GS V2/RC6GS/RC4GS.








QWhat’s the control range of R8SM?

A:The control range is 2km in the air. The maximum range is tested in unobstructed areas free of interference.
