my modded zip vs. all my other cars

[natedogg4674]

yesterday i took my family of cars to some friends house and we got 4 of them up and running at the same time, i hadnt noticed before how unbelievably fast my modded zip is, its got the pcb from a knockoff bit in it, with red gears and red zip motor, this things hauls a**. i have another zip modded exactly the same but not as fast, for the life of me i cant figure out what makes this particular one so much faster. I gotta say though its my new favorite... for awhile i loved my Honda NSX bit, then my Nissan Fairlady w/ boost, but even it with boost and a NOS motor cannot keep up. I have another spare knockoff pcb, and a new zip i havent touched yet, i may be doing another swap here soon to get full potential out of my last untouched zip. Update coming soon....
