I finally got to fly the plane more than just a time or 2 around the patch this morning. The winds were calm, but forecast to increase soon. I knew I'd better get going if I didn't want to be bounced all over the cockpit. Climbing in smooth air is always a joy. Just trim for 75 mph and use the rudder pedals to point the nose in the correct direction. It feels like you are on the express elevator in a skyscraper. I headed toward Castroville (T89) as I knew I had enough fuel for my planned flight, but not enough for another day and we don't have fuel at San Geronimo (8T8). Castroville is only about 10 minutes away, so I stayed about 1500' AGL. I decided on one touch and go before landing full stop. The wheels kissed the runway near the numbers and I advanced the throttle. I was at nearly pattern altitude as I crossed the departure end of the runway.
After getting fuel, I took off heading back in the direction of San Geronimo. I was still a bit hesitant to go out of sight of the runway. If I stay between the two airports, I can see both runways. I climbed up to 4500 MSL, about 3500 AGL, and leveled off and let the plane stabilize. I set the RPM to 2950 and recorded GPS speed and heading in 3 directions. Later I plugged the numbers in an Excel spreadsheet that I downloaded from someone's website. The results were a true airspeed of 112 MPH which was only ! MPH from my indicated 111 MPH. I'm not sure what the difference is, but this engine seems to have a bit more power than the one I had before. Before, I probably would have been closer to 107 MPH. I don't get it, because I still have the same pitch in the prop. The only thing that has changed is the engine and it was turning the same RPM. Maybe slightly less.
After about an hour of flying circles between the two airports, I decided I'd better go back. As I passed through 3000', I found out that the winds had kicked up. About 50' from the runway, the air smoothed out and I made a reasonable landing. No bounces and not hard.
During the flight, if I pushed the throttle all the way in, I would hit 120 MPH indicated (at) 3200 RPM. Climb could be as high as 1200 FPM. At 75 MPH, I was seeing around 800 FPM. CHT's are a bit uneven and a bit high. The left reads around 390-400 degrees. The right was 390 on the first few flights, but has dropped to 375 degrees. William Wynne reused many of my parts from the previous engine, but he had to replace one of the pistons, so it may be taking a bit longer to seat the rings on that cylinder. Oil temps are settling in at 215 degrees. The first couple of flights, they were pushing redline rather quickly.
After the crank broke, I decided that I would get a wood prop and get it dynamically balanced. That is in the process. I ordered a wood prop from Tennessee Props. I didn't know exactly what pitch to get, but fellow I talked to there went through some calculations and comparisons and came up with 62X39. He said he'd send me the prop and I could test it. The prop could be modified a bit if necessary and after I was happy with the pitch, he could install the uralite leading edge protection to it. So far, they seem to be real nice folks to work with.

Randy,
You are getting some decent cruise numbers for an
HD. Congratulations on getting it back in the air.
As a reference, my left side runs hotter than the
right by about the same amount. I read somewhere in
Corvair land that 450 deg or more is acceptable for
CHT's in climb situations. The head temp redline in
the car is well over 500 deg. I'll try to find the
reference and get it to you. I am trying to keep head
temps below 450 in climb, and 400 in cruise, with oil
temps below 220 in climb, and 200 in cruise. Your
temps seem pretty good to me...

Congratulations Randy. I know you're glad to be airborne again. By the way, I saw your HD at the SWRFI last year.
