I started with a Sensenich FP on the RV-8A to save a few dollars. After 350 hours of I upgraded to a Hartzell blended airfoil CS prop (the one Van's sells). The performance gain is across the board - not just climb. Bottom line, any extra money should go to this prop before another box in the panel, the graphic paint job or that fancy leather interior.

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 knew up front that I would loose T.O. and climb performance and I did it just for $$$. CG has not been an issue with a firewall mounted PC-680 battery. If I were to install a CS prop, I would have to move the battery aft, I suspect to account for the heavier prop. One thing that I have noticed is that due to the low mass of the prop, when the engine is hot and at idle, it does run a bit rough and I do aggressively lean after landing. Dale N613DJ 109 hours now.

Yes, you may have to be cautious about baggage compartment weight with low fuel and heavy pilot and passenger, but the trade off is a 50 plus pound weight saving and no recurring prop inspections (not to mention about $10 aviation units in your pocket for fuel) I fly with RV-6s and RV-7s with constant speed props frequently and easily equal their performance except in initial acceleration and climb. If getting pushed back in your seat on takeoff and 2000 fpm climb rates ring your bell, then by all means go with a CS, otherwise you will be very satisfied with a Catto prop.

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.
