Volmer VJ-24 SunFun
The VJ-24 is Volmer Jensen's hang glider design built from aluminum. This motorglider is constructed of aluminum tubing plus fabric, and originated as a foot-launched glider. The VJ-24 was first flown in about 1975 and showed exellent controllability. Plans were available from Volmer Aircraft for $100.00. Materials have been estimated at $2400, with a building time of 250 hours.
Designated the VJ-24E, the Sunfun is essentially a simplified version of the Swingwing hang glider or powered hang glider. The wings are fabric-covered aluminum tube and are a rectangular-planform type braced by V struts. The two wheels are for ground handling only, so the Sunfun is footlaunched and foot-landed. A 10-hp engine and fuel tank are installed beneath the wing and behind the pilot so that takeoff can be performed without benefit of a steep hill. Wingspan is 36 feet 6 inches, and total weight is 110 pounds. The Volmer VJ‑24E Sunfun has a useful load of about 200 pounds, burns about 1.5USG per hour.
