Someone has offered to let me use their Warnke prop made for a 2100 Revmaster engine on my 2180 Great Plains engine. He is getting great cruise speeds compared to what I am getting on my Props, Inc. prop in a very similar KR. He measured the bolt spacing and the bolt pattern on the Revmaster is about 1/2" diameter bigger than the Great Plains. Does anyone know where I can get an adapter plate to try this prop? I could make one, but I would much rather borrow or buy one for this quick test. I would obviously order a new prop with the correct pattern if the Warnke performs good.
