Full feathering does get you somewhat more glide (if you dig in the = archives you'll find some numbers) but it also goes to full feather in = any oil pressure loss situation. One of our members had a situation where he had power but low oil = pressure due to a leak in the crankshaft. He was able to land it = because he did NOT have a=20 full feathering prop and his prop went to fine pitch instead. It's an = interesting point but I consider the conditions where it's relevant = extremely unlikely. As far as I can tell (no didn't do it yet) with the prop feathered and = the airframe clean you'll get about 600 fpm down at 120 knots. Over the rockies at cruise that could be useful.

Hello = guys

For what I have gathered so far the = lancair 4p has a glide ratio similar like a piano LOL In other words if = the engine quits then open the door, throw out your keys because there = is where you land LOL

Well, this might not be = true, or is it?

So how about the full = feathering prop ? Does anyone have experience with the before and after = installation? How much they cost and = data?

Thanks -- Ronald
