Charllie, I have a new 24 Volt starter in the box which came with an
0-360 engine I bought with this starter already on it at the factory
(someone canceled their order and I bought the engine as a package)If
you are interested I will make you a deal, Gary Bennett RV-8A

I think there are some that have done this. I wanted to because I
have a 172 with a 24 v system, and thought it would be nice to have some
parts commonality. I ended up not doing it because of the battery
weight, cost of some items was much more, like fuel boost pump. In the
long run it was much easier to stay with 12 for me.

Dennis.
800 hours ago, I had the opportunity to test several different props on
my RV8 (IO=390). I tested and still have a std hartzell constant
speed @ 76". It gave superior climb and standard cruise performance.
I then was offered the opportunity by Aero Composites Inc.. to conduct
an exhaustive set of tests on their propellers. The tests were conducted
on the following dimensions, 76", 74" 72", 70", & 68". All lengths
performed well, however here are some observations:
76" superior climb - ok cruise
74" excellent climb = excellent cruise
72" good climb - excellent cruise
70" ok climb - good cruise
68 " ok climb - goodf cruise
The Aero Composites propellers are on average 10 to 16 lbs lighter than
the Hartzell (std model) and 10 to 15mph faster than the Hartzell (I did
not test the new Hartzell blended airfoil, as it was not available at
the time of testing}

Hi All,
After much gut wretching and lost sleep I finally made a decision
about my last major purchase and decided to go with the Hartzel blended
airfoil 2 blade propeller for my soon to be finished RV-8.
Now I'm faced with one last (albeit minor) decision between the 72"
and 74" props. Any thoughts? The guys at Vans considered it literally a
"flip a coin" decision with little decernable difference between the
two. Any other thoughts out there? Noise, ground clearance (probably no
biggie with a tail dragger), ability to grind off tip of the longer one
if damaged. I will be greatfull for any opinions. Thanks!

P.S. Are you happy with your Hartzell blended airfoil prop?
