An upgraded version based on the RX8R receiver, it has all the same features including redundancy.

The Pro version has higher precision and lower latency. It’s deviation of PWM is reduced to 0.5us, and the delay of PWM output is 9ms less than that of the X8R in high speed mode. A feature that deserves mention is the decreased effect of interference caused by the ignition process.

Strong anti-interference performance in ignition process
Higher precision of PWM
Lower latency on the PWM output
Support redundancy function
Smart Port enabled and support telemetry data transmission
