Introduction: Knex Battle Car A.K.A. the 31415 Yakul
The 31415 Yakul has two rubber bands wrapped around a piece on the axle for propulsion. the large wheels allow it to travel farther, and give it speed. the bumper is the only weapon. It previously had a rod in front for flipping another car upside down, but it was unreliable, so I removed it.
We have a be nice policy.
Please be positive and constructive.
