Wichawk (Javelin Aircraft)
A side-by-side two-place biplane, the
Wichawk offers simplification, easy construction and easy flying to
the homebuilder. It makes an excellent first project, because it is
both simple and goof-proof. Designer David D. Blanton, president of
Javelin Aircraft Company of Wichita had the best interests of
amateur constructors at heart when he started developing the little
ship.
As a matter of record, Blanton started the development in 1964, and
didn't make the first flight until 1971. "It takes a long time to
develop a perfectly sound airplane with a complete drawing file," he
points out. The drawing file, we might add, consists of 50 sheets of
production quality prints, for which Javelin charges a nominal $125.
The Wichawk is designed to meet all FAA criteria.
The cockpit of the Wichawk is 36-1/2 inches wide, the same width as
a Piper Pacer, and easily accommodates two men. There's a baggage
area that will take up to 100 pounds behind the cockpit, but if you
like, you can build the Wichawk as a three-place airplane, with a
solo pilot's seat behind the two place front cockpit. If you opt for
this, Blanton recommends the use of one of the heavier six-cylinder
engines, and the mounting of the battery on the firewall to
counterbalance the added weight and moment.
