Matt,
Sorry, I do not record manifold pressure. Displacement - 2074 cc. It is a Remaster 2100D. Approx 70 hp.

Do you record manifold pressure at cruise? I like both RPM and MP. What is the displacement of N1852Z ?

Pulled throttle back during climb out to maintain at or below 3300 rpm indicated. Did not go full throttle again. Takeoff and climb out - very good performance. Leveled out for cruise. Adjusted throttle to achieve 130 mph indicated cruise speed. RPM indicated is 3200 rpm. Propeller felt smoother that previous props. Probably due to dynamic balancing just completed on the Dynavibe. Results. Good but want to confirm Tach RPMs. I will buy a new Tachometer next to confirm RPMs. From the Dynavibe testing, the old Westach Tach may be indicating approximately 200 rpm high. I’ll resolve this before proceeding with full throttle testing.

Griff, Hoping for the same type of performance, but obviously the pitch is different. I discussed it with the manufacturer over the phone. He is pretty sure the 49 pitch is what I need. I’ve always heard that the different Propeller manufacturers have a slightly different method of measuring the pitch. I am hoping to get the same exact performance as I had with the Sterba. I can’t see much difference visually on the shape. The Hoverhawk uses a clear coat varnish, white tips, the urethane leading edge is black. The Sterba just had some stain with its varnish.

It looks great! Looking forward to the flight test results, when this rotten wx breaks. Now, your old Sterba was 54/54, and this new Hoverhawk is a 54/49(L). Does that mean it’s a bit different than your old one?

KR2S repairs completed. Thanks for Griff Pickett and John Bouyea I have completed the repairs on my nose wheel and strut.
