Frequently Asked Questions
Is the R85C compatible with standard FrSky transmitters?
No. The R85C is only compatible with Radiomaster Multi-Protocol radios capable of fine-tuning D8, D16 or SFHSS protocols and cannot bind to native FrSky transmitters.
How do I bind the receiver to my transmitter?
On your Radiomaster radio, select the desired protocol (D8, D16 or SFHSS) and enter bind mode. Power on the R85C while holding its bind button; the LED will flash to indicate binding and turn solid when complete.
What voltage range does the R85C support?
The receiver accepts a DC input between 4.5 V and 8.4 V, making it suitable for 2S to 3S LiPo setups or regulated BEC outputs within that range.
