Information about image resolution and printing
  • The sheet design provides for splitting each sheet into 2 sheets of 35.9 by 19…22 cm size. This means that you can distribute each sheet to 2 A3-size paper (42 x 29.7 cm) and thus print it in the original scale of 1:50.
  • If you print each full sheet on 1 A3-size paper (or split them into 2 A4-size sheets) you arrive at a scale of approx. 1:62.5.
  • If you want a still smaller model you can print each full sheet on A4-size paper, resulting in a model scale of approx. 1:86.

Information about the original plane and the model, plus construction report

The model represents XP6M-1, one of the two prototypes of this plane (the 1st pre-production assembly was named YP6M-1). Due to rising cost no series production of the plane was ever begun.
The model was published in 1957 and only had this one print run because, due to the plane never reaching production stage, people soon lost interest.
The model can be constructed without undue effort but is still not recommended for beginners. While the number of parts and the level of detail are moderate by today’s standards, the model impresses by its sheer size.
