Built in 1922 by Eric Nessler in France, it arrived at Camp Mouillard on August 5, 1922. By August 15, the machine is ready and performs a few small flights on the plain with a maximum duration of 8 seconds. On August 17, it fell on the front, breaking the landing gear, seat and tail. It flew again on August 24 with a flight of 17 seconds over the Toupe plateau but was slightly damaged on landing.
On August 27, departing from the summit of Combegrasse, towards Aydat, in no wind, some jumps on the slope were made before final takeoff but a flight of 1 min 3 sec was made. During this flight, the aircraft succeeded in gaining height.

The design, by Robert Nesmith, is a conventional high-wing, strut-braced monoplane with fixed tailwheel undercarriage. The pilot and a single passenger were seated side-by-side with dual controls. The fuselage and empennage were of welded steel-tube construction, while the wings were of wood, and the whole aircraft was fabric-covered. Continental engines of C75, C85 and C90 can be used.
The first, N75282, first flew in March 1957.
With a redline speed of 195 mph, the Cougar maintains a brisk cruise of 120 to 165 mph, depending on choice of engine which can range form 65 hp to 125 hp. Landing approach is done at 80 mph and touchdown is around 70.

The original Cougar design was marketed by Nesmith himself. The design was modified by Leonard Eaves for an EAA design contest in 1963, principally for the purpose of including folding wings. When the modified Cougar won an Experimental Aircraft Association (EAA) design competition in 1963 that organization took over selling plans. Rights to the design were eventually purchased by Acro Sport.
The aircraft can be towed to and from the airport on its own landing gear.
The aircraft shape was influenced by the Beechcraft Staggerwing and Wittman Tailwind. The name came from the college of Nesmith’s daughter, the University of Houston, whose athletic mascot is a cougar.

The Nervures Swoop 14 and 16 mini wing were created in 2006 in collaboration with Val Montant.
The Swoop 2 16 is described as ultra versatile, for speedflying on site and hiking or paraclimbing version, it is ideal for an introduction to mini-wings with take off near a paraglider, a very healthy behavior, able to climb thermal and land comfortably.
The aspect ratio has also been specially designed for this surface to facilitate take off and provide dynamic flight behavior. Recommended to max inflight weight 100kg.
The Swoop 2 14 is a mini wing for experienced pilots for speedflying and paraclimbing. The aspect ratio has been specially designed for this surface, the short suspentage cone facilitates placement on the ground as well as elevation of the wing. In expé Version (1.9kg) it is suitable for short & difficult takeoffs, solid in turbulent conditions even in trimout position.
The Swoop 2 10 is for expert only, extreme speed flying or speed riding new sensations; compared to other mini wings of same surface glide ratio is widely superior, more efficient brake response and lower roll movement.
