Created airplanes
[edit]- P40: 1995, called Koala, evolution of P180S, also two seater all-metal low wing with fixed tri-gear
- P50: called Bouvreil (a wild bird)a first design from 1979
- P60: 1995, called Minacro(mini acrobatics)a double wing construction monoplace acrobatic with classic gear made from wood and fabric in very small dimensions
- P70S: 1977 S stands for simplified construction (as fast build, needs a very few tools)
- P80S: 1978, often called Coccinelle for ladybug - due to Pottier's first prototype painted yellow with large round black circles overall. A seat-by-seat mid-wing construction with several market succes in Europe (sold licenses)
- P100TS: 1980
- P110TS: 1980
- P180S: 1980, a two-seater all-metal low wing airplane with trigear. The protype was flown with a Continental O-200A. A big number of license have been sold. Amateur builder equipped engines like O-235, O-200, buth also a number of planes with Rotax, JPX, Limbach, Jabiru and others. The plane is light (depends engine, from 305 up to 390 kg empty ramp weight). The dimensions are small and the projected surface is little. all these facts results in good climb performance (O-200 at gross weight about 800 to 1000 ft per min) a well cruise speed (O-200: 100 kts @70% power) and a fine handling like military trainers.
- P190S: 2002,called Castor, a wood and fabric version of the so succesful P180S, one single plane was realised: F-PSCH lic/n 01 built by Mr. Jean-Robert Scherrer in France.
- P220S: 1995, called Koala, evolution of P180S, also two seater all-metal low wing with fixed tri-gear. This model was very succesful. The construction was simpified regarding to its previous model. The wing spare is simplier but stronger. control surface for the rudder was augmented to give more effectivenes at low speeds. The Czech company Evektor begun to produce a Ultra ligth version of the P220 from 1996 on.One year later, they produced a light sport aircraft called P220 AT2 under the market name "Aero", first builts had the fully name on the fuselage, later they renamed it to EV-97 Eurostar. The upgraded model, powered by a 912S Rotax was named Sportstar after several modifications at canopy, controls and flaps. It was the first certified aircraft under the new category S-LSA and became "LSA of the year" in 2011. Piper was anouncing in 2010 to introduce a new 2-seater / trainer named Piper Sport, based widely on the design of the Sportstar. Later on the marketing departement renamed the project SportCruiser. Piper finaly decided not to follow the project in 2011. The company Czech Aircraft Works has then followed the developpement and finaly brung to market the nowdays called "CZAW SportCruiser".
- P230S: 1990, called Panda, tree seater all-metal low wing with fixed tri-gear, biger engines
- P240S: arround 2000, modified P230S with biger engine (180hp Lycoming) and four seats. one single protoype was built
- P250S: arround 2002,concept variant of P220S no licenses has been sold out
- P270S: 2000, called Hamster, evolution of P220S, four seater all-metal low wing with fixed tri-gear
