The FGr4B receiver is compatible with all AFHDS 3 transmitters (Note: It is currently applicable to PL18 1.0.55, NB4 2.0.93 and NB4 lite 1.0.10 and later versions. The high-frequency library used by the firmware is version 3.0.).
The failsafe function is used to output the channel according to the out-of-control protection value set by the user after the receiver loses its signal and is out of control to protect the model and personnel.
If after a firmware update is performed and the transmitter is unable to bind to the receiver, the receiver may need to be put into forced update times.
The design is small and light, easy to install.
