I have an Aeroworks 25% Edge, no modifications, with a Moki 1.80. The plane will hover at 1/3 throttle, and does great precision aerobatics. However, it is no comparison to my Midwest Cap 232, 27%, in 3D flying.
I'm about ready to give up on that particular Edge flying 3D. Don't get me wrong, I like the Edge, but the Aeroworks 25% is not designed for 3D. I have seen what the bigger Carden Edge can do, and that looks like fun!
Just be sure to spend the money, and get an awesome motor for your plane!
