Your kit includes at aerodynamic plates for the wingtips, called “SFG’s” (side-force genera-
tors). e eect of the SFG’s is to add stability in roll through 3D maneuvers. All of us, even
our pro team pilots, prefer to use SFG’s on 67” aircra.
Your SFG’s mount to the wingtips with thumb screws and clear plastic spacers as shown.
ere are clear plastic pads as shown for the outside of the SFG’s to reduce wear. We like to
attach these to the SFG’s with Gorilla Clear Bond glue as shown.
