New balsa WR

This discussion area is for basic structure building concepts. Not intended for advanced concepts.
*Good Example: Balsa can bend with the addition of boiling water.
*Good Example: Triangle is the strongest shape for most applications of bracing.
*Bad Example: Balsa can hold X pounds under these conditions.
*Bad Example: Use this shape for this application.
Basically I want you to think a design through with the basics instead of someone else thinking through your design for you.

So it took me 14 years to get a ratio this high but here it is: 104.235 pounds per gram of balsa was achieved today on a free standing balsa structure:

Do you have a picture of that somewhere. I am doing towers for SO and that effiency is pretty good so far my best tower is 4.3 grams.
BTW I love how you weigh each induvidual piece of balsa. That is more then anyother site i have seen does. I was wondering if you fly indoor duration.

I don't post pictures in fear that everyone would build the same.
