Pin down the bottom spar, space the ribs, place down the notched trailing edge, pin and brace the dowel leading edge in place... then add the spruce top spar... once all of the piece are in place on the board... use CA to tack glue all of the joints... once done (both wing panels can be done at the same time) add the vertical sheer webbing between the spars as noted... Wing done.. excpect for covering of course..
Note: I do add a triangle gusset at the wing tip rib/trailing edge... Just that strength monster in me.. LOL
Also as a tip for reference.. I like to add a few degrees of washOUT in the trailing edge wing tips... this enables the wing to provide stability and lift at lower airspeeds and for the wing to continue to fly so ta speak...
Yuppers... I got long winded again.. Yell if ya have any questions or concerns.
Can both the top and bottom spars be spruce?
