I would be interested to know the insertion forces of the main spar pins in
the current flying Europas. On mine it is essential that the wings are
supported and wiggled at the tips before the pins can be inserted. This
means that rigging cannot be done single handed without 13 ft long arms or
fiddling around with supports.
Ideally the weight of the wings should be taken by the structure (cups, entry
frame) such that the holes are in line before the pins are inserted, but I
have so far been unable to achieve this happy state despite experimentation
with packing pieces. Incidentally the pins drop in easily if the wings are
pinned to a jig accurately matching the cockpit module holes, so there are
no dimensional errors. How about it Jim N ?
