Flaperons with an inexperienced pilot are a crash waiting to happen.

sure... someone that knows how to deal with the function can get away with it. I would not have a problem flying the Avistar with flaperons and playing around at low speeds. A beginner would be 99% likely to pile the thing into the dirt due to a stall-spin when trying to get a lower landing speed by using flaperons.

If you had to ask if they would help... you don't have the flying experience to deal with using them, and you will wreck the airplane.

We've got to remember... these are beginners asking for what will work best to help them LEARN to fly. Not experienced guys asking how to fly specific 3D maneuvers. (like the waterfall which the Avisatar can do with Flaperons)
