Install Affordable Panel Frame in fuselage and test fit warm air outlet. I decided to modify the factory plan for the installation of the F-793 Angles. I will install the angle on the frame and the fuselage skin and make the warm air outlet and the frame removable. The order of the assembly pieces is as follows: panel frame, anodised warm air outlet, fiberglass hose connector. The F-793 angle will bi riveted to the skin. See pictures.
