Wanted to know if somebody could answer a question. What does a "programmable head" do? I have an Axe CP with bell/hiller mixing and it has an adjustable head with holes closer in or farther out on the blade grips. They come with the ball links both connected to the holes that are farther out. I'm sure some adjustment will make it more agressive and some will calm it down. Was just wondering if I could calm it down and then remove the weights on the flybar to end up with the same controllability but with a lighter copter. Plus, I just want to know what each change does and the affects on flight characteristics.
