It should. If you look in your RX setup mode and scroll all the way to the bottom, it should say iBus and set to channel 1. This should work fine. You need the FlySky FS-IA6B to use iBus though. And sometimes you have to flash the FC firmware to get the receiver communtication to respond. This happened to me twice, but they both started working after latest firmware flash to the FC.I think my flysky trans won't do ibus. I tried to set it but it won't work. Ppm is fine
