The Marendaz Trainer was a two-seat low-wing training aircraft built in the UK just before World War II.
It tapered to the rear, more in plan than elevation and carried a tailplane with a sharply swept leading edge mounted on top of the fuselage and externally braced from below.
The Trainer was powered by a 90 hp (67 kW) Blackburn Cirrus Minor four cylinder inverted in-line engine, driving a two-bladed propeller.
Marendaz hoped to sell it to the RAF as a primary trainer, but government policy was not to buy any for this purpose, and also sufficient engines were not available.
