I owned the Phoneix Decathalon with a Magnum 52 4c and it was a really good scale type flyer. Definitely a two stick plane. Loves coordinated rudder with the ailerons. Really not even close to being overpowered with the recommended engine size. I loved mine and did some crazy stuff with it and that eventually lead to its demise. Would do some really awsome snap rolls and almost come to a dead stop when entering a snap on a 30-45 degree upline. Looked really cool. Didn't look so cool when it when staight in! Oh geez, I will just have to buy another one soon. Its definitely not a trainer type plane but, if your experienced with tail draggers, you'll most likely find success with it. Exceptional quality for the money. I couldn't begin to kit build such a plane for double the money. If I buy another I think I'll go up to a 65-72 size engine for a touch more ooomph!
