The Evolution prop should work OK on the TT .46 Pro. I just ran in an Evolution .46 on an Alpha 40 using the stock 3-bladed training prop for a student and we tached it at 11,660 RPM. You'll get around 13,300 RPM or slightly better from the same engine with an 11 X 5 2-blade on it.
Yeah it's sort of opposite to what I was thinking. Makes sense based on stuff I've read about the prop. Even if it has less pitch, in a manner of speaking, it "bites into the air more firmly".
