I know a couple of folks that have changed from two bladed props on their 180 Skywagons to three bladed and have been disappointed with the performance. -------- Cate N4278S 680E Skywagon N180PK Read this topic online here: http://forums.matronics.com/viewtopic.php?p=327676#327676 ________________________________ Message 2 _____________________________________ Time: 08:51:43 AM PST US Subject: Re: Commander-List: Re: NICE FLIGHT From: Tylor Hall MT Propeller did a 5 bladed conversion for the 690 and did not get any performance improvement. I think there is a STC for the 690 from Dowty Propeller that is a wide cord 3 bladed prop that did get a performance increase. The Mr RPM conversion seems to have a low thrust issue with the prop that is approved. MT has a new STC for the Comanche 400 with the IO-720 engine. http://www.mt-propeller.com/en/entw/stcs/pa24_1.htm In the photo on their web site, you can see the new design is wider.
