i have a .21 boat motor with a big ol head on it with a mousse can muffler i made for it, and it turns a 9x4 prop at real high rpms, somewhere in the low to mid 20000 rmp range, and was wondering if this would be suitable for a combat plane or would it be too heavy, or too much for a combat plane that has a 36" wingspan, and 32" long fuse, or should i go with a bigger combat plane???
any questions, comments, queries would be greatly appreciated
