So our tower doesn't hold more than 1 kg... efficiency less than 1 :lol: fail

What are some of the best efficiencies you guys are getting?
And if our base keeps breaking, what would be a good way to fix it?

The base of the tower or the test base that it rests on?

Im pretty sure he/she means the base of the tower.

i meant the efficiency of the tower as a whole

They were talking about your second question.
As to your first, 40 should be very competitive.

we have the exact same problem. in general we are trying to make our top lighter because if the base breaks first, it means we have unneeded weight at the top(so ideally, a tower should have the base and the top simultaneously break?)

to make the base stronger, you might want to add one more truss on each face of the base, or make the main sticks on the base less slanted. You can do this by making the 4 main sticks on the top slightly slanted, and changing up your dimensions. That way, the top will have slanted sticks and the base will have slanted stick but the sticks on the base will be less slanted.

I just tested my first 2 towers of the season at an invitational and they both held 15kg. The efficiencies were 14.5 million and 15.2 million. I think i have my design down, now I just need to experiment with different types and dimensions of wood.
