Joe...I sent you an email with a .wpd file attached. Hope you can open it ok. If not, let me know and I'll copy/paste it into another email.
Thanks Steve. great infos! I just have to open it with the word program.
I've repitched my second Tornado 3-blade to 3.75 pitch, and also reduced the middle station #5 to 4" pitch from stock 5". I should be able to run at slightly higher rpm. will see how that works out.
