What an airplane! This is the classic design that got R/C aerobatics off the ground. It was the first successful low winger, designed in 1957 by Fred Dunn. Astro-Hogs swept 1st. 2nd. 3rd and 4th place at the '58 Nationals. Model Airplane News proclaimed in mock disbelief, "An airplane to top anything so far in multi RC. OUT OF THIS WORLD MANEUVERABILITY. Good pilots do four point rolls - so help us!" And that was before proportional radios. Berkeley Models put out a kit and hundreds of fledgling R/C’ers learned to love the Astro-Hog's near perfect aerodynamics. Those ageless flight qualities are still perfect today.

Inside or outside loops, snap rolls, For .45 to .60 Engines spins either direction, and inverted flight are effortless. Sensational 71" Wingspan stability. Perfectly powered with an old, but still good, pre-schneurle .60, Wing Area: 824 Sq. In. like those you find at most club auctions. Or it's a real dreamboat with one
