Since 1957, thousands of modelers have been delighted with the slow flying, yet fully aerobatic, flight performance of the original ASTRO-HOG. As the old saying goes, "NOTHING FLIES LIKE A HOG!". Well, now you can have the same easy flying aerobatic performance in a sport biplane design - the SIG HOG-BIPE.

Nothing Flies Like A Hog . . .

Just like the ASTRO-HOG, the HOG-BIPE performs any maneuver in the book, yet flies slow enough to let you enjoy it. This is barnstorming at its best!

The HOG-BIPE kit is fast building and easy to assemble. Computer accurate parts that fit together perfectly make it easy for the average builder to successfully assemble an accurate, straight flying biplane.

The large photo-illustrated assembly manual takes you through every step of the assembly.
