Radiolink is a high technology manufacturing company dedicated to researching, manufacturing and marketing of RC model radio transmitters. Our products included: RC transmitter, flight controller, receiver, GPS, drone etc. We are committed to providing customers with a high reliability and high performance product solution, as well as providing technical support and friendly after-sales service.

*Excellent Anti-interference: Support SBUS/PPM/PWM signal output, 2.4G 8 Channels with FHSS algorithm reduce overall signal interference.
*Long Range Control: Outstanding range over 1.2 miles in the air, good choice for FPV drone, fixed wing.
*Reverse Polarity Protection: even the polarities are mistakenly connected which not damaged. Support 4.8~10V high voltage servo.
*Easy to Bind: wireless bind to transmitter only 1 second.
Works with many types radio T8S T8FB RC4GS RC6GS.

S-BUS and PPM signal change:
1.Quick press the ID SET switch 2 times within 1 second, the signal is changed from PWM to S-BUS&PPM.
2.Red LED indicates PWM signal output with 8 channels totally work, blue/purple LED indicates SBUS&PPM signal output, 8 channels totally work.
3.SBUS and PWM signal possible working at the same time with SBUS&PPM signal output working mode. CH1 output S-BUS signal, CH2 output PPM signal, CH3 to CH8 output PWM signal at the same time.

How to bind with transmitter:
1. Put the transmitter and the receiver close to each other about 50 centimeters.
2. Turn on the transmitter, then power on the R8EF.
3. There is a black button on the R8EF, press the binding button in one second until the receiver light starts blinking and release, after about 8 times blinking, match code success when receiver signal LED always on.
