Blanton Wichawk

Javelin Aircraft Corp Wichawk



Designed by Dave Blanton, the Wichawk is structurally similar to the Boeing Stearman biplane and is stressed for up to 12g’s positive and six g’s negative. Standard seating is for two in a side-by-side or tandem configuration, which is rather unusual for a sport biplane of its type. Optional tandem or three-place seating is also available. Designed to  take the Continental O-470-11 engine of 225 hp, the 180-hp Lycoming is most often used, and can be adapted to house various horizontally opposed or radial engines. The wings make use of wooden spars with light alloy ribs, while the fuselage is constructed from welded steel tubes.
