Most of the Supermaxxes I build are built out of the rarest of the rare and the hardest of the hard to find parts, a lot of times they are NEW parts, which are almost impossible to find now-a-days, so those Supermaxxes aren't run because the risk of damaging the new, the rare & the hard-to-find parts is way too high! These trucks are displayed, not run, so that the parts remain new, rare, and undamaged...thus retaining their value!
I do, however, build some Supermaxxes out of parts that have already been used, are scratched, or have simply lost their value somehow...these trucks I do run, and they are a blast to run! Supermaxxes are stronger, handle better, drive better, and are just more fun than pretty much every other vehicle in their class!
On a side-note; Once I am done building a Full-Blown Supermaxx, no matter how rare or expensive the parts are, I always make sure that everything works properly...I will run the SM in the Living Room just to make sure everything works properly. That way there is no chance of damaging any of the parts!
Post some pictures up of all these SuperMaxx's!! We love to see sweet rigs. I have seen your Lightning but that is it.
