well i actually got my first race with this new chassis. after setting my ride height and my droop right, the car ran good. i had to loosen the rear ball diff. because it was too tight. it never loosend on me nor did i break pulleys. i did manage to break a C-hub on the last lap of the b-main. outside of that with the jaco dbl pink/orange and dbl pinks in the rear the car rode like it was on rails.
