Obviously that design wasn't anything serious...but that form of lateral bracing isn't very effective. Try X's next time.

To get a perfect arch, the balsa would have to be the same density throughout the stick, then multiply that by two for each side. When a friend of mine was competing in gliders, she told me that she baked the balsa somehow to get the arches.
What advantage would an arch give anyways? Would you be gaining strength or losing mass by using them?
Besides the A frame, I've also built a bridge that looks similar to the example on the rulesheet. However, I changed up the crossbeams and main supports to what I thought would be more efficient.

I knew they would be lower than the boomilever and tower scores but i didnt know it would be THAT much lower. 800 seems very do-able.
What were some of the other top scores?
