Yes, both ailerons UP (spoilerons) loses lift; both ailerons down (flaperons) increases lift. As traffic said, if you have something like a DX7 transmitter or similar, you can set up both of these on the flaps switch, and program it so that the flaps/spoilers turn OFF if you open the throttle past a (programmed) point.

Most planes tend to turn upward with flap, but some do the opposite, so whatever you program, you will need to experiment to find out how much elevator is needed to be mixed in to negate the change in attitude in either case.

If you program ailerons to go DOWN with UP elevator (a built-in mix on DX7), you will get super tight turns/loops. If you program the opposite, it will tend to increase any harriering you attempt, but beware! Having the ailerons to go UP with UP elevator may significantly affect your ability to pull up sharply from a dive. Ideally, you should try this on your simulator, if you have one.

Hope this helps!...Chris
