Sterling Piper PA-12 parts

Here are the plastic parts for Sterling's Piper PA-12.  This is a balsa stick-built plane.  I wound up laser cutting the balsa, but still needed these few plastic parts.

Plans for the plane can be found on AeroFred:  https://aerofred.com/details.php?image_id=91332

Printing instructions:

Cowling:

• Super Quality  0.12
• Generate Support:  TRUE
• Build Plate Adhesion: Brim
  • Brim Line Count: 8
• Initial Layer Line Width:  125%
• Bottom Pattern Initial Layer: Concentric
• Connect Top/Bottom Polygons: TRUE
• Bottom Layers: 3
• Top Layers: 0  (really, you want zero!)
• Wall Line Count: 2  (though maybe 1 would be better for weight, but not very sturdy)
• Initial Layer Travel Speed: 35
• Infill Density: 0%
• Z Seam Alignment: Random

Unfortunately, can't do this in vase mode and get the cutouts to work in the front.  The above settings work pretty well.  A little sanding and spray paint to match your colors.

The motor mount, compass, hubs - print how you like.  The photo shows a 2211 1300KV motor installed.  You'll have to file the motor mount to fit your specific plane.

Tires:  Print with TPU
