Its good to find other people who enjoy R/C's as much as I do. I'm lookin to rebuild my Tyco collection and exchange info on these fun lil cars. First off, I was wondering if anyone has info on getting replacment gears for an Aero Turbo Hopper & a 9.6V Turbo Blaster (the middle gear that gets switched back & fourth from "S" to "F". both of mine are kinda mangled. I've managed to fix everything else the cars but that. Any help would be greatly appriciated.
