Not bad at covering job! Well i aready beat you all, i built mine for almost 5 years! After all going thought girlfriends, family problems, and all of those things that prevents me from competely finish it. the first flight was last week and it flew so good. I was expecting it would be snappy as those .40 planes but instead this one is better. It is powered by O.S. .50 SX or FX i don't remember. No mods at all, a pure somethin' extra. I will get pics soon.
