Step 4: Marking And Making The Wings, Fins And Elevators
Fold the wing down along the 1 inch marks you made at the front and back. Then unfold them and cut along the fins' lines. Then mark out the elevators. Measure 0.5 inches outwards of the wing root and make a mark. Then measure another inch further out and make another mark. Then measure 0.375 inches inwards from each of these marks and make lines.
Once you've cut the elevators, pull the center fin up and through the fuselage whilst folding the outrigger fins downwards. Then fold the elevators up.
