RE: OS .46AX engine - best prop?
I finally got around to trying the APC 12.25 x 3.75" prop on my twist. I hate having that heavy, sharp finger mangler on my airplane, but I got to admit... it sure does haul it around nice. I don't think I lost much speed from the 12x4, but the vertical is noticably better, and I can almost get it to prop hang. (It's still nose heavy, so it won't hover just yet. Plus I'm not that good!) For safety reasons I really like having a wood prop on, but I gotta give it to that APC, it sure does work better. And you know, I can't even tell it's gray with the engine running.....
