It was a mid-wing cantilever monoplane with straight, thick section, constant chord wings of quite high aspect ratio (8.45).

The lateral division was at about 65% chord, with the rear part joined to the front with conspicuous V-shaped faired underwing hinges.

[3] The fuselage was rectangular in cross section, with a single place open cockpit at the wing trailing edge, baggage space behind and an inverted in-line 30 kW (40 hp) Train 4T in the nose.

A straight edged tailplane was mounted on the upper fuselage longerons and carried elevators with a small cut-out for rudder movement.

The E.1 had a conventional undercarriage with cantilever main legs hinged on the lower longerons, rubber sprung inside the fuselage.
