The Brushless 240S looks pretty good in there. Just have to find a good way to route the ESC wires.

Well finally found a suitable belt for the pulleys Powge S3M516, so 516 teeth.
Looks a bit silly as its only 3mm wide but sourcing a wider one from Xray hopefully.

Also sorted out the CVD's
Found an easier solution for the rocky, ran the 3racing universals for the optima ( very reasonably priced) and swapped out the M10 x 5 x4 mm bearings for M10x5x3mm, gives 2mm of wiggle room and they fitted nice with some shimming.
Also the Tamiya hard outdrives splines fit right up to the factory diffs and easy to source
Tamiya OP-218 #53218 Hard touring.

Think ill be cutting a new top plate and chassis next year, want to play with the battery/motor weight a bit more.
Have a good Christmas everyone, see you next year.
