Strut angles for diff props.

[recloosetrav]

I was just wondering if anyone has change there strut angle for a three blade to a two blade. I run a cf 45 and cf 42 right now. (making sure what metal prop i want.) Would a negative strut angle help a two bladed prop or would it just get out of control?

Negative stut angle may push the nose down too much and cause it to run too wet. It also puts more stress on the drive train. It would probably slow down some as well. If you run too much positive, you will get a teriffic rooster tail, but loose speed as well. It's a balancing act.
I'm no expert, but I could see where different diameter props could benefit from a change of strut angle. Just trial an error
