Greetings all. This past weekend I converted my RV-9A from a Catto 3 blade prop to a Whirlwind 200RV. Since this is my first constant speed prop I have a lot of learning to do and one of the things that I need some help with is glide ratio.
With my Catto if I pulled the power my glide ratio was about 12:1. When I pull the power on the WW200RV my airplane feels like its practically dropping out of the air. I doubt my glide ratio is much more than 6:1 (not measured, guestimate). I know the prop is designed to go to the high speed stop on a loss of engine oil pressure. If thats the case my glide options just became seriously limited. Am I missing something?
I know this will generate a few opinions and a few questions so for those of you who are going to ask things like "why did you do that" or "what are the pro's and con's" I posted some of my thoughts to my blog. http://www.darinanderson.com/2017/07/fixed-pitch-to-constant-speed.html
