You guys have helped me alot. All I hear is putdowns about the US41. I was wondering weather or not to put one in my 1/5 scale TF p47. Now by reading this I have made up my mind. The trouble these days is that everyone overpowers every thing . they think that if you dont have a zenoah or 3w the planes will never fly. Myself I am going to cover my bird with monokote not paint and fiberglass. I don't compete in any contests, I build for myself not the group around me. Again thanks
