Got a huge pile of paint chips. I finally got to fly it this morning. This made a definite improvement. In climb it performed better than it ever has. It seemed like I could keep it in a 105kt climb indefinitely. Oil temp 190 F, CHT usually < 400F. In cruise at 2400rpm with my fixed pitch Catto prop and 40 or 50 F rich of peak I was able to run at a little lower fuel burn than usual. usually it's about 8.5gph. This morning it was about 7.8, which I take as a sign of better cooling. It warmed up when I was motoring around the pattern at 80kt with full flaps, but no where near as bad as last week. So I'm pretty sure that remoiving all that paint from the fins had a benefit. Conditions were not identical - OAT was a couple degrees cooler and last week there was an inversion layer - it was 80F at 6500 ft - but I still think it is distinctly better now. -- Tom Sargent, RV-6A ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV-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/rv-list Browse Digests http://www.matronics.com/digest/rv-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.
