Got pictures?To secure the wing pivot, I made full bulkheads to keep it in place instead of the 'trapping pin(s)'. I also added a couple of protruding square pegs on the forward inside bulkhead that fit into matching recess 'pockets' on the foil edges, which work in combination with magnet latches so when closed, the foils would stay in the correct alignment, being prevented from rotating by the pegs. Essentially, I built in stops to eliminate the 'flopping wings'. A second set of magnets hold the foils in the open position and proper alignment.
I made patterns for the bulkheads if anyone wants a copy...
