There is a lot to designing a strong and lightweight wing spar for a foam airplane.
Back to Kilo3D
I am almost done with the Pickerel design, so my thoughts have shifted back to Kilo3D. Kilo3D will weight about four times as much as Pickerel, so it will need more strength from wood. As I explain in this video, there are a lot of wing spar design options, but some work much better than others.
I packed a lot more information into this video than I have into my previous videos. How do you like it?
