RE: Planning on upgrading to a 19T drift motor
on a 2wd the teu101 might take a 19t but youll soon fry it. unofficially you can only run up to a 23t motor on the teu101.
dont get a 19t drift motor get a tamiya tz and mod it with bearings or a good stock motor like a p2k2 or a co27 and tune those motors. and get a better ESC, its a once off buy thatll last for ages.
spend cash on something like a Novak GTX or LRP v7.1 etc.
