If not then I don't have your answer. I have tried several props and the 447 will work great clear down to a 4600 rpm cruise speed and stay loaded properly with 2.58 gearbox and 66x32 Tennessee wood prop or a 60" three blade IVO. BUT an Ultra Prop has that drop off that makes it seem like the carb or pipe, because of the lack of twist in the blades Trust me on this as I did lots of testing and spent lots of money to find that out. -------- Dennis Long Oakland TN 1990 Kolb 80+ hours since June Read this topic online here: http://forums.matronics.com/viewtopic.php?p=314178#314178 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
