I have flaperons programmed on one of my Mojos and spoilerons on the other. Ideally, I guess you would want a three position switch so you could do either one on the same plane, but my radio doesn't do that. My radio also doesn't allow for coupling with the elevator.

I don't really deploy them very often, and I don't have them set with enough throw to really ruin my ability to land the plane.

Flaperons on my Mojo 40 allow for REALLY short takeoffs and tighter than normal loops. The spoilerons on my Mojo 60 make for really tight waterfalls.

They can be fun to play with, but keep the throws small.

The other thing to watch for, is if you use full ailerons while the flaperons are deployed, you could end up overextending your linkages. Just make sure there is plenty of throw in every situation.

Good luck
