Some years ago I designed and flew a little .09 powered model for the old "Galloping Ghost" control system. When the small propo systems came along I continued to fly it with a .15 engine, using rudder elevator and engine control only for many years. It could and did do all the manuevers nicely, including level inverted flight - with a flat bottom wing, yet. It was very fast, very touchy and would never be classified as slow or puttering. I still have it in my shop and one day I will probably put a more modern radio in it and fly it again.
