I studied the plans and the manual some more, deciding whether to work on the
stabilizer or the fin next, decided on the fin. Identified all plywood, foam,
spruce parts. Stripped the peel-ply off the factory made main spar. This took
quite some effort. Cut 1mm plywood shearwebs for the front and rear spars. Cut
to length (+ some extra) spar caps from 10x10 and 8x8 spruce. Sanded the plywood
ribs to clean up the loose fibers. Sanded the 4 foam ribs that are to be glued
with plywood. Glued the ply+foam ribs with wet micro mix. Glued the spar caps
onto the webs with cotton-cab mix.
