A F3B/F7B may only need smoke and sound?
FWIW, this is the application I'd be most interested in. I've never used the coupler function on the Mini Commanders I have installed but the ability to use one of the HC outputs for smoke has been important.
Of course sound capability is kind of the Holy Grail; I've had to use ERR's little dummy engine board for that. Pardon my ignorance GRJ but I don't know whether the components you are thinking of using allow for sound.
ERR's Softset programing was very convenient but I could live without that.
