I had a 3" extension on the Little Beast. I flew it for 185 hours without a hint of a problem. The engine was originally a Gilbert Duty that I re-built twice. It started as an 1835, and I sufferred a cracked case behind #3 cylinder, so got another case and re-built it to a 1915. This was all with the same crank and hub extension. Jerry and I have a 3" extension on this GPASC 2180. This already has a "force 1" hub, so I don't know if we have too much or not. Probably if I were doing the extension again, for this engine, I would not go over 2". Richard Shirley had a 2" on his 2180.
Both hubs were aluminum. Remember, your results will vary. See you in Mt.
