The angle of between front and side frame is 112 deg and between the two side frame is 137 deg. The odd angles are the tradeoffs from making the frame length whole numbers (24" and 15").

The extra verticle beams in the hex frame is not necessary but good to have. One it can diverge the side impact force from the gearbox. Second, it can serve as superstructure / mechanism mount.

As for the wheel, we choose colson in the center for its durability. But our drive subteams needed more traction. So we decided to use Versa Wheel on the side. However, it's always possible to swap on other type of wheels, onmi or performance.
