I have two of them..one with C&H ignition and the other with a spring starter..Am using a Zinger 22-8/14 wooden props...Both are in my scale planes and they run very good..Be sure to grease the spring statrter at least once a year..other then that, I have no problems with them..Probably best to ask someone in regards to props to use on your stunt plane..Check out the Metz props....I really don't know what size you can use....Good luck...
