wing root shim into two 1-1/8" long pieces Trial fit the
shims, sanding them down until they fit between the

canopy and covering on the wing Use medium CA to glue
the shims to ribs R2 on both sides of the canopy, then sand
them to match the shape of the wing

together and secure with tape Carefully wick thin CA into
the joints Do not use accelerator, as this may permanently
weaken or soften the plastic.
