Confused about repitching/bending prop please help
Ok so I was out yesterday and my RPMs where at 8220. So today I removed the prop and marked it 1in from the trailing edge. Then I added exactly 1mm of pitch to all four blades bending the prop at the 1in mark. I measered it from the 1in mark that I made and made sure it was 1 mm. So I took it out and ran it and I am now at 8180. So I noticed that in the how to section the pictures show a mark in the center of the blade. Is that where you are supposed to measure the bend at? I mean do you bend the blade at the 1in mark until the blade starts to bend at the center mark of the blade? Thats what im confused about. Where to bend it and where to measure it. So do you bend it at the 1in mark and measure it at the center mark on the blade? I must have sort of did it right cause the RPMs did drop a little just not enough. Please help

You start bending 1" up so that you don't try to bend the very back of the blade where you take the measurement and end up with a big nasty kink in it.
BTW, if i'm only pitching 1 mm i start 1" up. If i'm pitching 2+ mm i start further up that than.
You want a nice gradual progression..... no kinks!
