The Airplane that Wrote the Book On R/C Aerobatics

This is the legendary model that got R/C aerobatics off the ground in 1957. As the first successful low-wing R/C model, it swept the top four places at the '58 Nationals and pioneered the unlimited aerobatic capability we take for granted today.
Obviously the Astro Hog is no longer competitive with today's high-tech pattern ships, but it does offer the modern sport flier amazing aerobatic performances in a super stable, easy-to-fly model.

The Astro Hog will perform any manoeuvre in the book, yet it flies slow enough to let you enjoy it! So gentle, some people have used it as a primary trainer. Ideal for 4-stroke engines!

Nothing flies better than a Hog

Michael Leys
Astro Hog. The first “pattern ship”

Designed in the very early days of RC, the Hog is an easy to fly model to fly. It was built with more stability than modern models but flies well if not as well as the current pattern ship.

A great model to build flying and building skills.
