I've lawn darted mine A LOT and it has taken it. I think the bodies have suffered the brunt of my damage.
My servo came loose but that was an easy fix.
My belt was slipping and it messed up the front pulley but I think that was because I didn't have the tension set up right. I will go on the tight side next time.
Other than that, this thing is great. Just a pain to do fast fixes on .
