the wing tips and one bay off each side of the non-aileron wing.
The non-aileron wing ended with a rib at each extremity. Then
cut the bay from the the wing tips leaving each wing tip with a
rib on the inside.
Took the aileron wing panels and cut the spar, LE & TE flush
with the first inside rib and tip rib. So I had wing panels with
ribs at both ends.
Glued the original wing tips to the ends of the aileron wing panels. Cut a
slot in each joining ribs of the original and aileron wings flush with the
shear web so when glued together I could pass a piece of CF through the ribs
and glue it to the shear web.
The wing span is right at 62". A real floater!
