Here are the images with the dimensions of the delta.

Wing length is 83 cm.

And here is how the KFm-3 airfoil is done. We'll add more instructions about this later, but if you're impatient you'll be able to use these images to start your delta.

Gorilla glue is used to save weight. Hot glue weights a lot more.

We sand the leading edge, it is cut at 45° and then smoothed.

This is what the finished airfoil looks like.
