The trainer that I don't use much has a OS LA 40 on it and I was thinking it might be fun to put that motor on a Magic for a kick around plane. I know it wont be a power house but every on at our field said that, for a LA it pulls my Avistar around fast, and to them it seems strong. Has anyone tried a LA 40 on a Magic? and what prop would I use, if I go this way.
