In 1934 a move to Hanworth was made and the prototype ST 10, G ACTS, was built. The 90hp Pobjoy Niagara powered ST 10 was a much refined version with redesigned forward fuselage.
With H M Schofield at the controls and the designer as passenger, G ACTS won the King’s Cup of July 1934 at 134mph.
Only one other ST 10 and two retractable ST 11s were built.
