My Jammin X-1 CR conversion

yeah i tried a lot of different weights in it. the heaviest oil i have found is the kyosho 500,000wt. it helped and im sure in a race scenario it would be a lot better. i just bash though so i went back to forward only and it wheelies more which sucks as far as trying to keep it on the ground, but i did quit splitting the front tires. thanks for the tip though
