Hi all,
The leading edge plywood 'saw tooth' fairing is tricky to do, but can be done.
Structure drawing of 1/72 scale resized by 160%, then printed, cut out and used as a template on 0.2 mm thick plastic card.
The fairing is test fitted and adjusted where necessary then secured in position using thin CA adhesive.
Starting on the top of the front wing spar then once set, rolling the wing over the fairing and applying adhesive at the same time.,
