How To Make The UltraSpectre Paper Airplane

Step 4: Marking And Making The Wings, Fins And Elevators

Fold your airplane up along its center crease. Then make marks at its front and back 1 inch above this crease. From the rear mark, measure 1.25 inches inwards and make a mark. Along the center crease, measure 1 inch in from the trailing edge and make a mark. Connect the center crease mark to the one you made in the middle of the wing. At the wingtip repeat this process. Make a mark 1 inch from the wingtip along the trailing edge, measure 1.25 inches inwards from that and measure 1 inch from the trailing edge along the wingtip and make a mark. Then connect the two marks with a line.

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.
