I talked to Mike about this chassis, basically we would be willing to look at it. If it can at least pass a safety inspection, We would let it run the first night. I assume looking at the pictures that the basic geometry of the kart is the same as any other.
That being said, RWYB refers to the motor, not the chassis. I can see in some ways this opening a can of worms for people wanting to push what is allowed and what isn't, If that were the case it would no longer be allowed. All track specific rules would apply eg- slick tires, chain guard, etc
