12/31/2012. Remarks by Johan Visschedijk: "The sole TA-5 (s/n 68583) was an enlarged TA-3 with a 200 hp Wright J-1 (Lawrance-type) engine used solely for test work at McCook Field under the Project Number "P-283". One experiment replaced the normal landing gear with a single landing wheel under the nose and outrigger-type smaller wheels on the wing tips."
