I recently asked the same question, "I want a fast aerobatic plane that can perform some 3D". A you can do 3D or a Twist are not "fast" planes, but will do about 70ish. I went with an extra 300s from phoenix models, and I had recommendations from someone with an aeroworks edge 540 who said that on low rates his was super fast, and at high rates can do 3D stuff. The big control surfaces on the actual 3D planes will cause flutter at high speeds. I have heard that flying a twist straight and level at full throttle is not good on it. I pick up my extra today, so I can't tell you how she performs yet.
