Now it gets a little trickier. In forward flight the advancing blade will tend to hop as you go faster. The purpose of the trim tab is to raise the trailing edge of the blade to get rid of the hop. If everything is behaving itself the reading on the balancer should be xx ips @ 180 . It is difficult to explain why it is always around 180 degrees but it has to do with always being the advancing blade and the 90 precession offset.
So the trick is to bend the back of the trim tab down, which will force the blade to a flatter pitch as the speed increses.
The closer to the main rotor shaft you mount them the faster the ship has to go for them to have any effect. My are mounted at 24" from the blade tips and are effective at cruise speeds. The only problems is that they are right where my blade clamps for my trailer attach. I had to modify my blade clamps to fit. Before mounting make sure you check for this issue. I don't think a foot or so will make much difference in how effective they are.
Again take notes on how much you bend and how much the ips change. There should be a linear relationship.
