Here's one of my AFX drag chassis! This one ran a 0.569 @ 38mph. 3ohm motor with polymer motor magnets. I used a modified Tyco Pro crown gear. That gear alone really woke this baby up!! I just got my Dash magnets! Now I need to build another to see how the magnets stack up. If I go to a lower ohm motor, I may be able to match the performance of the poly chassis at a much lower cost. This stuff is too much fun!!!!!
