It will be cheaper and more successful (also less painful) just to start with a 3D capable platform. Not trying to discourage you, but a reality check is in order. Look at a LOGO 20 or a Minicopter Joker and some of the soon to be available High Output LiPolys and you'll have an airframe capable of 3D, then it's up to you as the pilot.
