All cars have weakness if bashed hard.
but these are pretty hardy.
mine gets good level of abuse.
As for motor bearings I have seized a few. I run it in dust that’s like concrete dust and it ends up clogging most things up eventually.
i use Ezrun max 10 motor and esc in mine so won’t go into what I think of the blx stuff.
the pivot balls wear out very fast (cheap plastic. ) But you can get ally or steel upgrades when the time comes. They wear too, just slower.
front bumper breaks quite easily, but I cable toe mine up and keep going.
the original servos were pants, but the v3 may have been upgraded. Someone here will tell you.
tyres wear out fast.
to use other wheels and tyres it’s best to change hex for 17mm versions as there is a big market in that size. Otherwise choice is limited.
Shocks used to be rubbish and leak very quickly. Not sure if Arrma have addressed this issue.
so all the above sounds like there’s tons of problems.
don’t be put off I love mine and they are pretty bullet proof.
I crashed into a tree stump last week. Approx 45 mph, Sent the car 10’ in the air , barrel rolling hit the ground and flipped and barrelled for 30 yards.
landed on its wheels and drove strait off for more.
upkeep is way more extensive that our granite for some reason.
butI love it. Sure you would too.
