sentences:  In 1922, the Army ordered three TA-3 (Trainer, Air-cooled, Type 3) machines for evaluation with the Le Rhone engine and dual controls.Evaluation showed that the type had the makings of a good trainer, but was somewhat lacking in power, so in 1923 Dayton-Wright modified one TA-3 with a more powerful 110 hp (82 kW) Le Rhone.The USAAS then ordered ten examples of this improved model, and these were the last U.S. Army aircraft to be delivered with a rotary-engine.
