Aymar Demuth to Catto 3 blade
Neal,
I miss the Christin Eagle sometimes, but the RV is such a relaxing and fun plane to fly, I am glad I made the trade. Tell Tim hello for me. Phil |
OK, slow progress on getting real numbers but I do have close ones that I will narrow down in the next week or so.
This weekend I flew from new orleans over to the thomasville, GA fly in. Fun time nice group and great food. I only stayed for sat but many were camping over the weekend. so, on the way back 10,500 2400 rpm ~140mph ind /168 true 2500 rpm ~148mph ind / 177 true The A/D was ~10mph faster two things that come to mind, the three blade has a larger diameter nosecone and I am now running 20lb crushplate. would you guys expect these to reduce speed by ~10mph? just looking for similar experiences and thoughts. I am very happy with the prop and it is smooth now that I rotated 1 bolt hole clockwise (why this did anything I have no idea) |

A measure at WOT at the similar weather conditions and altitude. That would be your best static data point to start from. If you have accurate fuel flow and MAP measurement- use those also. Then you could measure similar power settings/conditions at what TAS. The RPM setting is a minor power data point with different prop comparisons since that will vary. |
You know I never thought about it, I have no idea what my power setting is with my setup ... Just picking rpm at altitude. I will get wot at altitude so then approx power setting is known.
