The cruciform tail surfaces were unbraced cantilevers and carried aerodynamically balanced elevators and rudders. The Fokker V.1 principal innovation was its unbraced cantilever wings. Rudder and elevators were horn balanced and the tailplane was of cantilever, unbraced form. There are eight braced sections to the tower above an unbraced bottom section. This type of unbraced wing is called a cantilever wing. The fabric-covered fuselage carried an unbraced tailplane, without elevators but with turned-up tips. For cantilevers or overhangs where the free end is unbraced, C is equal to 1. The roof to the nave is supported on three crown posts on unbraced tie beams. Bows were about long when unbraced, similar in size to the famous English longbow. The swingarm was a new unbraced, rectangular-section extruded design.
