The only official S series model built, with only a mere 35 pre production units built. Trials will be conducted with a select few squadrons and companies, to determine this aircraft's military role, strengths and weaknessess, and design flaws. Engineers at the Thunderbolt Palmer company heavily refit the C series, and applied the S varient's principles to its design. The designers now payed full attention to the aircraft's manuverability issues and strength handicaps. Reshaping the wings and again rebuilding the aircraft' elevator/ pitch control design flaw, the designers were able to build a fighter that flew a top speed of 1353 MPH at sea level, and was able to withstand g forces of 11.4 G's without the fusalage collapsing under the stress. Also fuel capacity was increased by 253 full US Gallons
