that they resembled, the rudder and ailerons of the first Travel Air biplanes had an overhanging "horns" to counterbalance the aerodynamic loads on the controls, helping to reduce control forces and making for a more responsive aircraft. These were the distinctive Travel Air "elephant ear" ailerons which led to the airplane's popular nicknames of Old Elephant Ears and Wichita Fokker. Some subsequent models were offered without the counterbalance, providing a cleaner, more conventional appearance with less drag. Pitch forces could be trimmed out with an inflight-adjustable horizontal stabilizer. Different, interchangeable wings were offered, including a shorter and thinner wing known as the "Speedwing" which improved speed. A considerable number of engines were installed, including nearly every mass-produced engine in the range available at the time, and a number of more obscure prototype engines, as can be seen in the list of designation prefixes. Travel Air entered the specially-modified Model 4000-T in the

Both would fly while Travel Air retained its identity, but would be incorporated into the Curtiss-Wright line with the same numbers.

Variants were distinguished with prefixes and suffixes in a particular order, and denoting different fittings. The prefix S, preceding all other prefixes meant it was a Seaplane and was fitted with floats. Next it was wings. B was the Standard wing, not to be confused with the original basic elephant ear wing, and D indicated the aircraft was fitted with a Speedwing. The engine code followed this, and due to the long service period when considerable experimentation occurred, a wide variety of engines were installed in production airplane as follows: :*A - Axelson B engine 7-cylinder radial engine :*B -
