Static is about 5,000 engine rpm with a 2.17 redrive.

Bob,
They claim that the prop loses 4” of pitch at take off. That
would give you a 68 X 80 during static runup. What static rpm do you get
when you do the runup? Do you have the 2.17 or the 2.85 ratio drive?

The prop is a Prince P-tip composite propeller. 68” diameter x 84”
pitch. See http://princeaircraft.com/

That really makes an aerodynamic installation!
Needlenose! By the way, what kind of prop is that?

Bill,
There is baffling along the sides of the radiator and oil cooler
that cause all air entering the nose bowl openings to pass through the radiator
and oil cooler (instead of around them) before it exits the bottom, where a
large cowl flap regulates the amount of air flowing through the engine
compartment. See the attached pictures. The oil cooler is at the
top of the radiator. Initially, my oil got too hot at high power
settings, so I added a second Mazda 13B oil cooler (in series) and placed it
right in front of the radiator. It worked, and the oil temps are now
about 10 degrees cooler than the water. I keep the water temp at about
180 degrees F most of the time and never more than 200 degrees F.
The plane flies beautifully and is currently being painted.
Stay tuned for pictures of the finished project.

Bob,
I noticed that you have the radiator mounted at an angle behind the
engine. Tell me again how you are ducted to and from the rad? What
about the oil cooler? Where is it and how is it ducted. What about
any cooling issues? How is your plane flying now that it has been a year?

There’s also a guy in McKinney.
I can’t remember his name, but you could find it on the EAA website.

Al,
I am about 70 miles SW of DFW at Pecan Plantation (0TX1), and Jason Hutchison
also has a rotary-powered RV-6A here. Feel free to visit anytime.
Neither of us is an A&P.
