So we are half way home. Also came to the conclusion that the prop is too long and the engine is too loaded down. As long as you keep the Firefly in a shallow descent, the engine does not hunt at all, it stays at a constant throttle setting. Raise the nose and load up the prop and it falls off the pipe. So now we need to learn what is a good length of prop for a 277 with a 2.58:1 gearbox. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kolb Firefly Part 103 legal Kingsport, TN 3TN0 Forgiving is tough, being forgiven is wonderful, and God's grace really is amazing.

Can you measure the pitch? I've got a couple of props around here I can loan you if we can get close.
