Built Bridge Problems

[kitsume13]

(Didn't see any threads that already covered this)

So, Our team had Just finished a bridge to test on and we ran into a balance problem.

Our bridge's center of balance is off and we cannot find out what is wrong.

We built the bridge according to the low expense blueprints, it's made out of plywood, it can hold the required weight, but balance still off.

Has Anyone else had this problem? If so, how did you guys fix it?

Thanks!
