something somewhere along the line bothers me tremendously.
Hartzell. Unless you have a solid crank then Senseninch. I beat Mike Thompson in a race last year because he had to slow down and deviate around light rain on course with his Catto.

One other thing, NO WAY am I going to install a CS prop now. I can just imagine the posts LA would be making about me going completely over to the dark side.
Soon. Very, very soon.Sounds like its coming together. I'm waiting anxiously. Let me know if you need an extra hand.

72" Diameter x 64" pitch

As much as I like the looks of the three bladed prop, everyone who has one complains about how difficult they make it to get the bottom cowl off.
Bill, These "everyone" who complains about cowling removal probably have the tail wheel on the wrong end.
I've had my Catto 3-blade since December of 2003 and we don't have any problem at all getting the cowling on or off.
That's what I had with the old engine and I loved the prop. It always cracked me up when people would look at with disbelief when I would tell them it was wood....and it's very smooth. Craig simply knows his stuff.
Best,
I could de-rate the engine but why bother? I can always pull back on the big black t-handle when I get close to Vne.You could de-rate the 360 to 160HP. Cessna starting in 95 came out with a restrictor plate I'am told to keep the HP at 160 and for the SP model that plate was taken out. .... Ron

I heard back from Craig. Nadine was confused and thought they were cutting a new prop for my O-290, just as I had suspected. Here are the numbers he is projecting for my O-360:
Updating the numbers, as promised.
Bob,Good catch - when I saw your pitch number earlier (64") I thought to myself there is no way this combination has a chanch of reaching 210 mph at normal rpm speeds. Still I am dubious but then I have no experience with your combination. If you hit 210, even at 2750 rpm you will be a high contender in the RV Blue racing class (www.sportairrace.org). Good luck with that - as if I needed more motivation. Back to work on my new wing tip molds.

........ Then all that will be left do to is fit hang the engine, fit FAB, fit the cowling, and install all the probs. That should take a week at most.
Hey Bill,
ECI is supposed to ship my tappets in 7-10 days. At that point I will be down to just FWF on mine. If you don't get the lead out I might have to fly mine down there to help you get airborne.
After 16.5 hours of work, the top and bottom cowls are on and attached at the firewall. There is still a lot of work left to do, such as rivet a piece of aluminum along the horizontal part line to hold the Skybolt fasteners, layup some fiberglass in the nose area, next to the spinner for platenuts to hold the nose together, cut and fit the oil door, and a few other things.
A number of people have compared the James Aircraft cowl to the Van's and said the James is of better quality. I'm not so sure that is true.
...
In the looks department, ADVANTAGE James cowl. That thing looks fast just sitting there. IMveryHO!
