Mike from CT here. I am hitting a problem with making my wings. I seem to be building wash in to the wings with horribly snappy, unflyable behaviour resulting.
I use strips of pine about 6 mm thick as the spars and I shape them into a taper from the chord end to wing tip as per the plans. Normal procedure for me is to glue the spar to the bottom of the wing and then make the fold and glue the top of the spar to the top wing skin and close the edges at the same time.
Can you suggest a way I can build in washout each time? I was thinking of placing a 5 mm packing piece under, say the wing Trailing edge near the tip and then gluing a sort of half rib to the wing bopttom skin from the spar back to the TE to fix the washout in BEFORE doing the fold and final stick down.
Think this will work, or have you got a better way?
