the backer plate:is it wood?
if yes then WHOA!!u must have made a record as 1st person using wood in RC.
In case u dont already know , the plate is to support the diff gear so that it doesnt strip in a crash/mishap
i tot it was wood cos it just saw the sides which were seeping with oil?
on ur last pic there was lot's of Carbon fibre below the diff...was wondering where to get them?
i wanted to make myself a 3mm chassis...and maybe make one of those chassis stiffeners like yokomo.
