Answered: Counter-weight??

Are non-vex metal counter weights allowed to be used on robots? I have read the rules and I don’t see why not.

Rule <R5> lists the parts allowable for robot construction. It limits you to ONLY official VEX products, and then lists a few additional components. Non-VEX counter weights are NOT official VEX products, and they are NOT listed on the additional list, therefore they are ILLEGAL for competition use.
