G`Day
Am not sure what to do!!!!

Am building the Top Flite 1/7th scale P-51, and on the plans it shows the trailing edge of the wing has to be sandedso that is has a concave groove, and on the Flap leading edge it shows to sand this a convex shape.

How do you attach the Robart hinges so that there is only about a 1/16th gap when the flaps are installed at the downward position?????

Have tied this procedure on a trial piece of balsa and every time the flap is lowered on the demo the hinges pull out, leaving a gaping gap when the flap is back at neutral position!!!!

Have some photos of the plan attached!
