At the Zachary contest this weekend, I took Dracula, the older, now backup airplane. On Saturday I was using a prop that had no drive in the warm, mostly dead air filled with thermals. Doug Moon had been advocating for two blades for a while, and I had a couple with me and decided to throw one on to try it out. The difference was amazing! Almost too much drive but great feel throughout the pattern. That prop made Dracula feel almost exactly like the Ferrari plane
After working on the prop and retrimming the airplane a bit, I noticed the airplane had developed the smallest of hunts in level flight, inverted was still tracking very well. This is something Doug mentioned he could feel switching to a 2 blade as well, but he felt the hunt in inverted flight. The only question I have is why the two blade doesn’t track as well as a 3 or 4 blade prop does? It was a very slight but noticeable change I could feel in the plane
