very few parts on it break so you only need few different spares and the car is easy to correct mistakes and friendly car to drive, was my first 4wd car at the start of last year and i was very impressed from the start and it's taken me all the way from the bottom to the top bunch now
Only broken a few front wishbones and front shock shafts in over a year weekly indoor and outdoor races with a fair amount of abuse! Never had a problem with the carbon bits or had to replace any of the carbon parts! Rarely have to carry spares on me either as theres almost always what i need trackside for it at prices that don't break your wallet either
