RE: Tune pipe and prop size for kougar
why would anyone trying to make cougar go faster with a 11x7 on a 46 size engine,is beyond me, 16k on a 10x6 prop with a mac's pipe is gonna make it move , cutting the header isnt any big deal, i am sure some here has a os 46 running a pipe, but no one is running a 11x7, i am running 4" header length on a 46 os , but i am spinning a 10x8 at 14 plus on a much lighter airframe
