I have now done the 5hrs of flight testing and these are my impressions. 1 - The CATTO is beautifully built and machined piece of art. I had mine painted white with the nickel leading edges, Copper colored tips (matches the tail number) and Carbon Fiber Spinner. I love how it looks as can be seen in the attached photo. 2 - The CATTO came in 19.8lbs lighter than the Sensenich propeller. This shifted the CG 5/8" aft, still well within the CG limits of the airplane no matter how I load it. This change in CG made all the difference in the world on landings. I no longer run out of elevator authority on approach and can now softly ease the nose gear on the runway. No more dropping nose. I actually made 3 "squeaker" landings in a row. The good thing is that it did not change any other flight characteristic I tested, specifically the stalls under different loading configurations. 3 - Right now it looks like it might be pitched a little too much since I only got 2,625RPMs at 7,000DA and full throttle. However I did pick up 5kts in cruise and I don't have the nose wheel boot on which will add several more knots in cruise speed. The climb isn't much different that the Sensenich. 4 - I also got an additional 8" clearance between the propeller and the ground which is excellent for "rough" field operation. 5 - The propeller isn't as smooth as I thought it would be but I think I have it incorrectly indexed and part of it might be the recently overhauled engine. Once I have about 50hrs on the engine I will get it dynamically balanced and this should make a big difference. As I fly and test, I will post the results. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kis-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/KIS-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/kis-list Browse Digests http://www.matronics.com/digest/kis-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.
