Every goofy thing I do or set up on a plane is set to a switch. Sometimes this takes a lot of trial and error to set up the way I want it to. I have the spoilerons set up on one plane, a 68 inch Extra. I have taken this plane up, way up, before I tested them to see what effect it would have on the plane. They work but you may not like the effect at all. I still have the set up in this plane but will remove it, there just isn't any reason for them on a nice stunt plane that I really like. The wing looses lift and the plane will drop very fast. It's just a spot landing trick that is a lot of fun on a fun fly type of plane, the guys at the field think it's cool but it really does scare me if I don't hit the switch soon enough to get full control back. Both systems mentioned can really kill a plane in a hurry if you aren't thinking fast. I like the flaperons on the Hots but it isn't used all that often. If you are like me you have these little things you can do with your radio and want to try them, go ahead and give them a try but they often don't do things the way you want. Do everything way up high and understand you will have to do some adjusting. I have even had my Hots start stalling on landing on calm days with my set up so be aware it will happen. I had flaperons set up in most of my Up-Roars and liked them but I was in a lot of fun fly contests back then and did a bunch of odd stuff.m I don't even teach this stuff to students, I leave it as a live and learn thing but if asked I do warn against it.
