I tried exactly what you are asking and I was not pleased with it. Using the ailerons as flaps (flaperons) makes it much more unstable in any kind of winds and requires more skill with the throttle. I agree with the posts above. If you really want flaps, add them between the ailerons and the fusalage, but this plane really doesn't need them. You just have to fly it enough to get comfortable with how it lands. I've been flying mine for almost two years now and I can land on pavement in less than 30 feet on a calm day, less than 20 in a good head wind.
