joey, can you put up a link to the ARF plane you bought & possibly a pic of your engine? I'm a little concerned as to rather or not you matched your plane to the engine as these days there aren't too many .25 size ARFs left on the market & only few of them are Trainers. Let's start by making sure this stuff is going to be a good match. If you can give us some more specific info on what you have, we can better know how to help you.
