Model Background

The BT-15 was used as a basic training aircraft for the USAAF and the US Navy.  Basic trainers were used as the second step of flight training during the WWII.  Basic trainers had more powerful engines, variable pitch propellors, and flaps.

There are two basic variants of this aircraft, the BT-13 and the BT-15.  The difference between the variants was the engine.  The BT-15 used a 450hp Wright R-975-11 engine instead of the 450hp Pratt & Whitney R-985 used on the BT-13.  The US Navy also used the BT-13, but the Navy designated this type the SNV.
