K'nex Airfoil

Welcome to my instructable on building a k'nex airfoil!

I designed this airfoil in the likeness of a balsa model airfoil. The airfoil is constructed of many "ribs" linked together which can then be covered with paper/cardboard or the like.

The structure is quite flimsy, however I plan to reinforce the structure with two 1/4 inch steel rods which will slide into the holes on the connectors in the front and rear of the wings.

I have built two versions of this wing. One large, and one small. I envision two different sized planes using these wings: 1. A very large plane using the large wing as the main wing and the small wing as the stabilizer. 2. A smaller plane using the small wings as the main wings with a flat stile stabilizer.

I built this a while ago, curious if I could build a working k'nex airplane with the same structures used in balsa airplane models. If I weren't currently working on another large project I would have attempted to complete the entire plane. However I still intend to build a complete working airplane out of k'nex someday.

Step 1: Large Airfoil

This is the large wing design. Link as many of these together as needed to achieve the desired length.

Step 2: Small Airfoil

This is the small airfoil design. Link as many of these together as needed to achieve the desired length.
