I have an SSE and a BalsaNova, both set up for flaperons. My Futaba 6XEA radio has a knob on the upper right to actuate the flaperons. Just not quite sure how to best utilize them, or when! I found that when I operate them, the plane wants to dive. I mixed in a little elevator and that fixed that but I find it difficult to take my fingers off the stick and actuate the flaperons and when I do, its difficult to guage how far to move the knob.....also, its not clear to me what the benefits are and when to use them. Because I'm not sure what to do, I typically leave my fingers off that little knob.

Anybody want to step up and give me a crash course? I'll appreciate it.
