RE: prop timming
thank you for all your input. the only reason that I asked this question was that the crankshaft dead time on a typical engine is taken up by the flywheel. And on most high performance engines the flywheel is balanced directly with the crankshaft. on my cessna 150 and 172 the propeller is timed to the crankshaft so thats why I asked. thanks again. if anyone has any more info please send along.
