Cozy
Like the Long-EZ, the design includes a retractable nose gear and fixed main gear.
With both front seats unoccupied, the center of gravity with the aircraft level is aft of the main gear.
Thus, like the Long-EZ, the Cozy is parked with the nose resting on the ground, sometimes called "grazing".
The nose-down position is very stable.
The aircraft can withstand high winds as the wings are beyond a flying angle of attack.
Some Cozy builders modify the design to include retractable main gear.
This modification increases the maximum speed by a few knots.
Maximum fuel tank capacity is reduced to accommodate the retracted gear.

Cozy III
The Cozy III was a 3-seat aircraft and the predecessor of the 4-seat Cozy Mark IV.
Also designed by Nat Puffer, the Cozy III was initially referred to as simply "The Cozy".
When the 4-place was announced, the qualification of the Cozy III name was required.

Cosy Classic
The Cosy Classic is the European version of Cozy III, changed to a forward opening canopy and other modifications.
The forward opening canopy design is available from Uli Wolter, the designer of the Cosy Classic modifications.

Aeromet Aura
UAV, realized on the basis of a Cozy MK IV in 1986.
Built in duplicate by the American company Aeromet Inc.for the US Army.
