Congratulations on your acquisition of a Maxford USA ARF PT-17 Stearman

!

 

The PT-17 is a biplane that was used as a military trainer by the US Army Air Corps during the 1930s and served throughout 

WWII. The PT-17 is also widely known as the Stearman, Boeing Stearman, Boeing Model 75, or the Kaydet. At least 9,783 were 
built and thousands of surplus PT-17s were sold on the civil market after the conflict. 

This almost-ready-to-fly radio-control version of the PT-17 is based on the aircraft that is owned by John Mohr, who very 

kindly sent us many detailed pictures of his personal aircraft. We also acknowledge and thank Jay Smith, editor or Model 
Aviation, for his help and advice on this project. 

This model is constructed mainly of laser-cut balsa and light plywood. As shown above, it is finished with a Mylar film 

covering. It may also be special-ordered with a flat-finish Mylar or as a fabric-covered and prepainted ARF. 

We invite you to enjoy the pride of ownership and the joy of flying your high -   
quality balsa and light-ply almost-ready-to-fly version of this historic aircraft.
