Flysky is preparing to release their first receiver FGr4 with the new AFHDS 3 protocol. Flysky AFHDS 2A protocol is one of the fastest protocols and Flysky promises that AFHDS 3 protocol will have even lower latency!
FGr4 receiver will have 4 PWM outputs (CH1-CH4), iBUS output and input for connecting additional sensors. There is also old fashioned bind plug for binding this receiver.
Receiver internal photos. Notice that this receiver has two (diversity) antenna connectors, but only one is connected for this version My guess – there will be a version with diversity antennas.
