See thats the thing i didnt buy the motor seperatly it came with the plane as an RTF, as far as i have figured out its an Evolution power traininer system which i believe is a .45 2 stroke. This motor should already be broken in according to Hanger-9, all your supposed to do is pull it out of the box, assembly, fuel it up and fly it. I probably should have called hanger-9 and seen what they say but if they asked me to send it in i dont want to be out of a plane and not get to fly till god knows when they send it back.

Thanks
