Hartzell Composite
 
Just ordered 2 blade Hartzell Composite 74" for the ~8 IO-360 Parallel Valve
Can anyone provide experienced feedback?

Besides looking really great, it's very smooth, pulls like a freight train when adding power and stops on a dime. Great for formation.

Can you tell I love mine?

Isn't there some possible issue with clearance / interference between the back side of the blades at full course pitch, and the cooling inlet ports on an unmodified Sam James cowl on an RV-8?

I sure hope not, because that was my first hurdle was the oil temp right after buying this SMILE MAKER:D
New baffling
New larger dual pass cooler
More clearance between #4 cyl and cooler
Please don't tell me I will go through that again.

With the 72" blended, I could hold tail up over my head and still had 10" clearance, I don't feel adding 1" will hurt me.

So I guess the only real question should be WHAT COLOR:rolleyes:

You won't have any ground clearance problems with a 74" prop. My friend's RV-8 with metal 74" Hartzell has tons of ground clearance. If you ever get nosed over that far on the ground, you've then got much bigger problems on your hand than just a prop strike!

Hey Stan - the prop will "pull" better than the BA. I have a data sheet showing 100 lbs more thrust. 800 std.

What cowl do you have on that 8? If it is the Vans cowl, you should be fine, but check it. I assume you did not get the extended hub?

RV8iator 11-03-2016 06:41 PM

The standard Vans cowl needs the G hub and the Sam James needs an extension I believe.

I'm still green at this stuff, I don't Sam Hill about Sam or who Sam was, but my plane kit was purchased in 2007 and first flown 2010 and the prop I ordered is from Van's
G2YR/N7605W-2X 74" Extended Hub composite 2 blade.....Requires D-4798-P Hartzell Polished Spinner

If I screwed up please yell loud NOW.

You have a standard Vans cowl. No problem.
