In setting up the wing panel receiver tubes, I set the cores on the working surface with the top surface down shimmed up .125" on each half at the root. This to allow a slight amont of dihedral eliminating the possibility of anhedral in the wing while in flight. Once everything is lined up equally, the tubes were then tacked in with 5 min epoxy.
Sub-root former placement is now traced onto the cores to allow .250" engagement of the tube end.
Foam is removed, the former temporarily put in place and traced to the airfoil shape top and bottom for final sanding. Excess air space will be filled with foam and final sanded to shape with the former. Former's get lightly epoxied in place.
This view shows the receiver tube dihedral offset.
