ahh yeh very true dude
touch wood ive had no probs so far, the thing i read about mostly with a tripped spur gear was when jumping if ya didnt have to alloy upper A arms cuz the stock plastic ones would flex a little & could hit the spur gear stripping its teeth
needless to say, when my stock carrier melted i had no idea what it was at the time, was somehwere in wales with a mate who brought his ST, 1 min my MB was boucncin about the next nothing! ..didnt suss out what it was until i got home & stripped it all down lol (spot the noob eh!!)
so after that i decided to slap on an alloy carrier but keeping the gear stock plastic, 1 thing im gunna get is alloy body mounts for ther side of my shell cuz ive gone through loads of the plastic stock ones, keep workin em selves loose (even when i use super glue to hold the thread!) & i end em losin em, so fkin annoying!
