Instead of yieldingly urging the upper section inwardly with respect to the lower section as shown in Figure 2, a cable 2| is anchored adjacent the inner end of the sec- 6 tion l8, and is extended partially through the section 20 to a pulley 22 rotatably mounted therein. From the pulley 22 the cable 2| passes through a suitable opening 23 in the section 20, from where it is suitably guided to a manually operated control means such as 24 which may be conveniently located within the ready reach of the operator of the flying machine. When it is desired to decrease the wing dihedral, the control means 24 is manipulated to shorten the effective length of the cable 2|, and when it is desired to increase the dihedral, the control means 24 is manipulated to payout the cable to permit outward movement of the section with respect to the section l8 by means of the lifting force of the wing.

Having described my invention, what I claim as new, and desire to secure by Letters of Patent, is:-

1. In a flying machine, a lower fuselage frame member and a pair of upper fuselage frame members converging rearwardly, a pair of outwardly converging wing frame members hinged to and projecting laterally from each of said upper fuselage framemembers, and a pair of. wing struts hinged to the lower fuselage frame members and each projecting laterally therefrom in converging relation to a pair of said wing frame members, each of said struts including a pair of resiliently connected telescoping parts.
