I am contemplating buying the Easyfly with or without the game commander. Is the game commander any good? Does it have duel rates and sub trims? Extra channels?

If I use my own transmitter, does it recognise the additional channels, etc?

If I get the game commander, can I still buy the interface to use with my own transmitter? The reason here - I can teach new people with the game commander without breaking my expensive transmitter.

Thanks,

Peter Gordon
