That big prop is a VERY efficient speed brake!!! (Don't ask me how I know this.) I suggest you set up you linkage to get full throw capability!

But you probably already knew that. Regards, Jim Ayers Less Drag Products, Inc.

We once had access to a Cherokee 180 with a VP prop and tested the rate of descent with the engine idling and the prop full coarse. Instead of about 1000 fpm we reduced the rate to about 750. There are two problems, of course. If you practice forced landings with a prop windmilling in fine pitch and then execute it for real at a substantially different rate of descent, how would that assist in hitting the mark? Secondly, we also found that the largest effect on the rate of descent occurred within the first inch or so off the fine-pitch mark. After that there was no substantial gain. So, it appears that if your restricted pitch travel doesn't compromise safety, leave it where it is.
