      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.
