| Subject: | O-360 and Catto FP prop |
I fully agree with Matt. 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.

Hi Scott,
Reconsider the CS prop. My RV-6 with an O-360 and a Hartzell prop is the
perfect combination of climb and cruse performance. 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!

I see the same enthusiasm on VAF for those comparing a Catto prop to
standard Fixed Pitch props. Catto props apparently are in their own class.
Back to the OP's question, I'd suggest asking on VAF or calling Vans.

No aft cg issues with Catto 3 blade on rv8. Understand there are with CS.
Do not assume prop bolts from Van's will work. Also, I ordered a special hub
extension from Saber. Check archives.
Limited funds, the KISS principal, and my personal preferences favored the f
ixed. I have not missed the CS prop.

My RV-6 performs quite nicely with an O-320 and a Sensenich FP prop. It han
dles loops, rolls, barrel rolls, and hammerheads quite nicely. I chose FP f
or cost and maintenance reasons. Getting the max performance was not a conc
ern for me.

I too have a RV-8 fitted with a IO-360 with a Catto prop. 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.

I installed a Catto two blade FP prop on my RV-6 with O-360 in 2004 and now, 1080
hours later, I have never been sorry. 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.

Subject: RV-List: O-360 and Catto FP prop
Hi folks,
I am seeking information from those who have installed an O-360 with a Catto three
bladed prop on their RV-7. 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.
