right now with our design, the top portion and the base are two separate pieces. whenever we test, the tower always breaks at that connection. we're trying to figure out a way of making it just a single piece but we don't know how to go about that. any suggestions?

The thing about C division is, the angle between the base leg and chiney column is more acute (not necessarily acute, but more so) than that of the B division bridge. As a result it's hard to bend a 50+ (actually probabaly around 53) centimeter piece of balsa with such a sudden bend, and maintain a reliable level of strength along the column.

That's my 2 cents on the topic, but who knows maybe someone's actually been able to make it one piece. Wait for others to reply.

How does that make sense...by making a smaller base, your cutting down on weight, why make the base larger than it needs to be?

I think it would be better to use the 15 X 15 cm base or a 20 X 5 cm ± depending on how well you think you would be able to balance it so it does not tip over

Has anyone here made a tower with a 20x5cm base that did relatively well?

We did build a 20 cm x 8 cm Division C tower, weighing 6.9 grams, that held the entire load. The team is working on reducing the weight further.

I got 1st at regionals with a tower with a weight of 12.5g that held everything and was a long edge tower. I found that it was much easier to stabilize two faces made of curved wood rather than two sets of two faces
