I had some fustration with bendig the Pitot/Static/AOA tubes for the ADAHRS. I first tried to do it freehand with a heat gun. Very dificult the tube would kink just after it got hot enough to bend. What I found to work best is to heat the tube on a mandral. I used a aluminum tube bending tool. Put the plastic tube on it and then applied heat with the gun and worked the tube around the tool.
