Step 8: Fold The Winglets And Tape; Make The Forward Fin Butterfly

Fold the winglets up 3/4 of an inch from the wingtip. Repeat on the other side. Then tape the aircraft together.

Optional:

To make the forward fin provide more stability, fold it over the wing root on each side. Once each side is folded, make sure they are both angled at 45 degrees.

I would make one, but I do not have the capability to make motion videos at this time.
