You can make them pretty strong but it's probably not gonna be worth it by the time your done with buying the steel diff,idler,making a strong enough motor plate for a bigger motor,adapting a suitable slipper to the top shaft(unless the new slipper is up to it and can take the revo gears-i don't know).the out drive shafts are smaller too aren't they?If you can make it work with bits you've already got then there's no harm in trying-except to the tranny,it'll probably go south.

yeah you could adapt the t-maxx trans,been done before.or you could just drop a centre diff in instead.
