Durability is very good with this buggy. I've been running mine for 6 months and haven't broken anything. Shock towers are nice and thick so they don't bend. A-arms are beefy and have a tiny bit of flex. I have bent the front left cvd bone but thats from having too much end point on the servo...esentially my fault. Also I just replaced the center cvd bones because the pins were worn down to half thickness.
