https://en.wikipedia.org/wiki/Consolidated_PT-3

The Consolidated Model 2 was a training airplane used by the United States Army
Air Corps, under the designation PT-3 and the United States Navy under the
designation NY-1.

Seeing the success of the Navy's NY-1 modification of a PT-1 airframe, the USAAC
came to the conclusion that a radial engine was indeed ideal for a trainer. It
was reliable and offered a good power-to-weight ratio. Therefore one PT-1
airframe was completed as XPT-2 with a 220 hp (164 kW) Wright J-5 Whirlwind
radial engine.

The XPT-3 was almost identical to the XPT-2 except for the tail, revised wing
panels and different shape. 130 production PT-3 aircraft were ordered in
September 1927, with one being completed as the XO-17. These were followed by
120 PT-3A aircraft with minor changes. The XPT-3 became the XPT-5 when fitted
with the Curtiss Challenger R-600 two-row six-cylinder radial engine, but was
soon converted to PT-3 standard.

The PT-3 aircraft were superseded by the Boeing PT-13 Stearman starting in 1937,
but a number were still operational with the Spartan Flying School in Tulsa
Oklahoma into the middle of World War II.
