the gearbox, when i started the design i made provision for the cr gearbox to be attached, however i also drew up a aluminium internal 4 gear box in pro engineer, to get this box CNC milled as a one off would be expensive and there was no guarantee that the car would justify it, so i had a problem, i didn't want to use the CR box as the idler gear mod is a bit exposed and to have mounting holes for both boxes was not practical, i have however an S2 4 gear box, a bit of measuring and adjusting the pro engineer file would allow me to use this S2 box and when the new box is made it would drop straight in.
first job was to strip and clean the S2 box

I modified an existing CR shock tower to fit to the car, the new planned box is designed to allow the Losi tower to bolt straight in without mods.

however a quick check with the S2 tower and it fits without moving the geometry around too much so i decided to use that
