This page covers upgrades I've made to the Trans. in my truck.
Now a Losi XXT plate, it is the same as the Jay Pede setup. This plate is mounted from the inside as in that of the Losi XXX cars.
Metal motor plates
Inside is a Dirt Burners top shaft to use a Losi dubble sliper set-up. If you have Hydro-drive you may use that. Top shaft has a Drelin gear on it. A alum. idler is used in the center with a stock gear diff. Fill the gear diff. with lots of heavy grease.
