I have a 60 size CG Super Chipmunk that I am currently covering. The instructions call for a 2 1/2" spinner for the nose. I am putting a YS 91 in the front. I bought an aluminum 2 1/2" spinner for it, but the holes are too small for the prop sizes for the YS 91. I asked the guy at my LHS about it and he said just to ream out the holes to make it fit the prop size. Should I do this or buy a bigger spinner?
