Wing Retainer System & Wing Lock Set
A) Wing Lock Set F-115. Wings will lock in place by using the snap fasteners. No tool needed to lock wings. Includes one set (see picture). Made in Europe. This set is very similar to the Multiplex lock set, which are no longer being made.
B) Wing retainer System F-116: Self locking system for wings. Suited for fuselage widths between 60mm/2.36in. and 110mm/4.33in. Holding power may be adjusted by using different spring washers. The screw nuts need to be glued into the wing. The couplings will be screwed in and adjusted to fuselage width.
