The VJ-24 was derived from the earlier Volmer VJ-23 Swingwing and differed from that design by replacing the wooden structure with metal and employing a constant chord, strut-braced wing in place of the VJ-23's cantilever, tapered wing.

The 36.5 ft (11.1 m) span wing is braced by V-struts, supported by triangular jury struts.

The fuselage is built around a keel tube that mounts the cruciform tail at the aft end, the wing and cockpit in the center and the engine at the front.

The specified engines are the Yamaha KT100 15 hp (11 kW) go-kart powerplant and the 10 hp (7 kW) McCulloch MAC-101, mounted in tractor configuration on the front of the keel tube, above the aircraft's nose.
