The Arpin had a fixed tricycle undercarriage at a time when most aircraft used the tailwheel configuration. It was the first British aircraft to be designed for tricycle landing gear. In 1938 a very unusual McClaren type was fitted, which allowed all three wheels to be turned parallel to each other but not to the aircraft, so that cross wind landings could be made with the aircraft pointing into wind. The front wheel could be left to caster or could be steered by the pilot.
