The Astro-Hog was designed by Fred Dunn towards the end of the 1950s. Here is a beautiful example built by Günter Hoppe.
Günter had already built one in 1959, at that time he flew this airplane with an 8-channel OMU pneumatic system.
The new Astro-Hog is powered by a Webra engine. Wingspan 1.83 meters
