The public debut of the aircraft was at the Cleveland National Air Races. The closed course midget racers had a minimum weight of lbs. The Midget Mustang's 9-G ultimate structural strength and low power loading give a true high performance fully aerobatic sport plane that can also be used for cross country flying. The cabin size will accommodate persons over 6ft tall.
Midget class racers were restricted to an engine of no more than cubic inches, a minimum wing area of 66 square feet, minimum weight of pounds, fixed landing gear and a structure able to with stand at least 6G. The Midget Mustang did not disappoint and finished 2nd in the elimination heat unfortunately not finishing the finals due to engine problems. As more powerful engines became available it eventually reached mph in competition flying. The Midget was not only a competitive race plane during the late 40s and early 50s, today it is an outstanding sports plane able to cruise comfortably at mph. Although designed as a racer Long had envisaged full scale production of the Midget as a post WWII sport plane and before his untimely death in in an engine failure crash had made arrangements with Schweizer Aircraft to start production. Sadly the market never developed partly because of the large number of surplus WWII aircraft available at bargain prices and partly due to depressed state of the economy. The Midget did attract attention from the homebuilders' movement that was then still in its infancy but orders were still slow and full scale production not feasible.
