Electronic phasing of a head with the SK720 software is very simple. In the Swashplate menu, there is an adjustment tab in the lower right corner called "Phase Trim" and that is your phase angle changing tab. You set one blade out over the boom then adjust the trim angle plus or minus until there in no movement of the blade when you move the elevator stick. You must make sure that the grip over the boom is exactly 90 degrees so that it will give you a proper reading. You can always make further trim changes if there is a tendency to move left or right when an elevator only input is given while in flight. You can change it with a computer or the portable LCD screen (optional extra). Phasing is very simple and it is done the same way whether you have three or seven blades. I have mechanically phased heads without the blades in place and still had success doing so. Take care.
