            Type
            Single seat aerobatic competition aircraft  
            Design Features
            Low wing monoplane with a specially designed symmetrical airfoil, 
            16% thick, conic nose and flat sides. Large symmetrical ailerons. 
            Wire braced tail surfaces.  
            Structure 
            Fuselage has a welded steel tube truss covered with sheet metal from 
            the firewall aft to the cockpit, fabric covered from the cockpit aft 
            the tail. Aluminium sheet metal turtledeck. The tail surfaces are 
            fabric covered and wire braced with steel tube spars and bent up 
            steel sheet metal ribs. The one piece wing is all wood, Douglas Fir 
            and Spruce spars, plywood ribs and plywood covered. Large span 
            ailerons are built of wood and fabric covered. The fiberglass engine 
            cowl is a two piece, split horizontally and is easily removable for 
            ease in maintenance.  
            Flying Controls 
            Pushrod actuated ailerons and elevator, cable actuated rudder. 
            Ailerons are mass balanced and aerodynamically counter balanced. 
            Each aileron is fitted with a ground adjustable balance surface 
            suspended below the aileron. A trim tab on each elevator also acts 
            as a servo tab to reduce stick pressures.  
            Power Plant 
            One Lycoming O-320 (150 HP) removed from a Cessna 172. Modifications 
            include inverted oil system, high compression pistons, and fuel 
            injection. Driving a two blade fixed pitch Senescing aluminium 
            propeller (74 inches diameter, 60 inches pitch). The fuel tank is 
            located in the fuselage ahead of the cockpit, capacity is 18.5 
            gallons.  
            Landing Gear 
            Non-retractable tail wheel type, main gear is a one piece aluminium 
            spring, tail wheel is steerable and full swivel mounted on a 
            cantilever steel spring. Main wheels are 5.00 x 5 with hydraulic 
            disk brakes.  
            Accommodation 
            An adjustable seat back nominally reclined to 30 degrees.  
            Systems 
            Electrical system of 12 volts. Electric engine starter.
