Monospar ST.10


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.
