ok i know i have asked before and i am down to the point of getting the final parts for the conversion. well after looking at other ejato conversion and i am gonna go with the mamba monster sytem in it and run it from 3s to 4s. cause i want to have power and keep temps down with a little higher gearing i have planned. plus im proably gonna use it as a base for a speed run rc. possible looking to break the 100 mph for my self. and ive seen people use them on plastic tranny cases. ive been told to look at the hot racing steel tranny case and i cannot find them at all. or am i looking for the wrong part?
