Despite the overlap of designers and the shared layout, Mauboussin's tandem winged Hémiptère was significantly different from Peyret's aerodynamically as well as being a powered aircraft.

Apart from its tandem wing, the Hémiptère was a conventional 1930s light aircraft, with a short, flat sided fuselage, a single open cockpit and a fixed tailskid undercarriage.

The front wing was mounted low on the fuselage and was unswept and of constant chord c = 1.30 m (4 ft 3 in), though with well rounded tips and with a generous trailing edge root fillet.

It also had a lower angle of attack: viewing this tandem wing aircraft as a biplane with a large negative stagger of c, the decalage was -3°.

The front wing surfaces could also work together to act as lift generating flaps but did not move differentially as they had on the Peyret glider to provide roll control.
