There were problems with this chasis.... it looks good in the pictures but not so good in your hands.
First, the front springs are too stiff and catch half the time. Second, with the rear suspension, where it pivots, the axle actually doesn't really move. In other words, it effectively doesn't do anything and just looks pretty. Third, the way he had the front steering was not going to work without axles that can't adjust their size as they move.
I'm not sure what to do with it
