Introduction

n this project, we will work through the design of a Limited Pennyplane indoor model airplane using OpenSCAD. This design will involve writing program code, something not may model builders do when building their models, but I hope to show that this is not too difficult, with a little help.

I will not try to teach you how to write programs for OpenSCAD here. Instead, we will present the design and explain hat the code is doing. Hopefully that description will help you see how to use this tool to generate your own designs.

The companion website at https://rblack42.github.io/math-magik/ presents Python code that will be used to analyze the design we present here, generating information about the model weight and CG location.

Design Presentation

Basically, we will work through all of the parts needed to build a reasonable Limited Pennyplane model. Along the way, we will generate a few components that are general enough to be used in in other projects. Those components will be placed in a library of useful parts we can use as needed. The OpenSCAD code for library parts will be detailed in the Library Parts.

If you find any of this confusing, and wish to help me clear things up so more model builders can benefit from this, please contact me by email:
