The marbler, truck and dyson.

It is as its called. The marbler when ahead of the truck shoots marbles in its path while a vacuum is at your heals cleaning up the mess (stops the 4000 length map slowing down) most of the time it will make it unassisted. Both vac and truck have rc activators so you can watch them do their work. Expression of interest. Anyone think they could make a car keep up with this. Max 2 wheels not jets or stabilizers. Will add a timer and take out the car for a comp if interested. Comment below.
