Thorpedo Light Sport Aircraft, depending on configuration has an empty weight 750 LBS with a gross weight of 1270 LBS. The aircraft is powered by Jabiru 120 HP 6 cylinders, the Jabiru 85 HP 4 cylinder, or the Continental 0-200, 100 HP. 

The Thorpedo Special Light Sport Aircraft is derived from the 1945 Type Certified Thorp T-211. John Thorp, a Lockheed engineer, designed this as a primary military trainer. The T-211 is a light aircraft by design, it is a low-wing monoplane of conventional design with fixed tricycle undercarriage and a sliding canopy. It bears some family resemblance to the Piper Cherokee, a design that Thorp contributed to significantly. 

Thorp constructed eight prototypes, and had the design certified by the FAA, but was unable to find a foothold in the Cessna-dominated post-war US market. The project was therefore shelved until the homebuilding boom saw the rights to the aircraft acquired first by Adams Industries and then by Thorp Aero in the 1970s, the latter firm building five examples as the Thorp Arrow. The kits were then manufactured by AD Aerospace in the United Kingdom and Venture Light Aircraft in the United States.
