The GW-2, which first flew in 1964, was the result of experience gained with the GW-1, and featured a longer (16.15 m./ 53.0 ft.) NACA 63(3) 618 section high aspect ratio wing with spoilers, V-tail, fixed wheel and skid. The GW-3 was developed from the –2 with an emphasis on simplicity. It had a NACA 4301 2A airfoil and flaps. The GW-4 followed on from the –3 with a higher wing loading of 30.66 kg./ sq. m/ 6.28 lb./ sq. ft. The GW-5 used a constant chord 15 m. wing to qualify as a Standard Class ship. As with the earlier models the –5 has a faired fixed landing gear. Flaps, are provided for glidepath control, and the tail is conventional. Specifications are for the GW-5
