I am wondering what prop would be good for this engine. Will be putting this engine in my Funtana X50. Want to practice hovering and do some other 3D flying. In reading about what other guys have been using on their set ups for 3D it seems like a 4 pitch is the way to go. My self I have always used some where between a 6 and 8 pitch prop. But if someone could give me some advice on what prop to use on this engine in this plane that would be great. Also what size 12 or 13 or maybe a 14?????
