Robert M. Simon, ES-P N301ES To Robert and Lynn, others; I have the MT 4 Blade on my L4P. the difference in vertical decent with the engine at idle and going form Fine pitch to Course pitch is 3500 fpm. A giant difference. With the 4 blade it is like a brake at fine pitch. However, others have told me that at course pitch they calculated a glide ratio of up to 25 to One. amazing but the speed it up there. I needed a glide number to put in the SFS EFIS because it shows a blue glide range around the airplane, corrected for wind and terrain. We all agreed on a more realistic 15 to One. One caution that I can think of with a full feathering prop is that you need a unfeathering accumulator if you want to get it windmilling and started again, otherwise you only have the starter. That said, I think Brent and Orin both lost a Turbo hose while at altitude and the engine quit from too much gas. I think Bent finally got it started at a lower altitude before landing. He can tell the true story, maybe? If you need more than 25/1 glide ratio than a full feathering prop will help.
