Hi,
I have been running the Futaba CGY750 for a while now and really like it. I made the switch from Spektrum and decided to go with the 8FG Super, the CGY750 work really well with this radio giving gain adjustment from the transmitter. The CGY750 also sets up very quickly and easily.
I have found that tweaking the 750 takes a little time to begin with but once you know your way around the unit its very easy and quickly done.
The CGY750 is able to be connected to other brand of receivers by using the SBE-1 SBUS Encoder, which connected to the SBUS port of the CGY750 and then converts to the standard connectors on any seperate receiver.
Hope this helps
Cheers
Ross
