Ptuey:

You have the idea down well enough to work with it.

After you use cut and try to get the best performance, though, you might find a commercial prop of the same diameter with a little more pitch works better, because while the cut prop works well, and we aren't losing that much eficiency we are losing some, and the factory prop could be better. But at the same time, your cut prop could be the absolute best match to your plane and engine.

And what was the absolute best prop in the morning might not work very well in the afternoon, with the lower air density.

But as I said, you have the idea, now it's play time. Get out your cutter and files. Start chopping.

Bill.
