Well done @jakemoore,
sorry I am late with suggestion, but the work was done perfect!
Coming from aircraft industry with the background of model making
/ This is only way to repair such a damage.
One point must to be respected! The angled cut of glasssfibre must to be at least
10times longer then thickness of the glasssfibre ! Laminate the same thickness
of glasssfibre into it, that is! With such a repair on the sail plane wing and the check
of controller the plane get the permission to be air born again!
touch and go
