I am getting ready to order my finishing kit and have one final decision to make before the order. My concern lies in a potential aft CG issue when installing an O-360 and a Catto FP prop. As I understand it my options are one of two installations. Option 1 is to install a weight of X lbs behind the prop to shift the CG forward. Of course, this reduces useful payload by X lbs may be the least expensive. Option 2 is to use a engine mount for a O-320 shifting the engine forward with the ensuing CG shift. This option requires an extended cowling (the Vans version might work, I believe I can order an extended Sam James cowl. Not sure about the Sam James cowl working.) This is the more expensive solution. If you have an RV-7 configured with an O-360 and a FB prop; would you mind sharing your CG issues if any? I appreciate any information you can give. As a final note, I have considered CS and have read extensively on the performance issues. I have decided on FP. Thanks for your time.

I love being able dial the prop back to 2350 for cruse. In the RV-8 with the same prop and the IO-390, I don't have the RPM restriction and routinely dial it back to 2150 with lots of MP for a REALLY quiet, high-speed cruse. Oh, and the climb is outrageous. I wouldn't own an RV without a CS prop! - Matt Dralle RV-8 #82880 N998RV "Ruby Vixen" http://www.mattsrv8.com - Matt's Complete RV-8 Construction Log http://www.mattsrv8.com/Mishap - Landing Mishap Rebuild Log http://www.youtube.com/MattsRV8 - Matt's RV-8 HDTV YouTube Channel Status: 172+ Hours TTSN - Rebuilding Fuselage After Landing Mishap...
