Barrys right on Brad, this plane is really a 60 size plane in a 46 size box
put the st on it and just us a 4 pitch and youll be happy, and i mean happy. and when you get the extra bucks you will want to buy a saito 82 for it, which is overwhelmingly the engine of choice for this plane, i have a saito 100 in mine and its not overpowered, its overly exciting[X(]
when you have any more questions just ask and all of us here on the ucd thread will be glad to help
