Just try your mix as spoilerons, then flaperons.. run a couple tanks through and see what you think. The spoilerons give more pop to a lot of maneuvers, flaperons are good for... tight loops.

If you have crazy vertical speed turn on your spoilerons and high rates and jam the right stick forward at full climb speed, as you cut the throttle. It's pretty neat, don't know if that's an actual trademark *3D* move or not. Ends up as inverted elevator but it's cool going over the top.

Just play with it, spoilerons are the way to go but you can drop like a rock, keep it high at first.
