Got my roll cage mounted (hpi102526) and i see it comes with updated fuel tank mounts which i like but i don't know what the big round cups are for someone said something about for the roto start but it doesn't make sense to me does anyone have any insight on this here is a pic with the cups.
hopefully the pic shows but if not just google the part number and go to images you will see it.
