I have had my buggy for just a little while, but I am very happy with it. Until I noticed (after two weekends of use) one of the rear outdrives was trashed. It seems to be a problem with improper heat treatment because only one out of the four outdrives was damaged. So I sent Horizon an e-mail and a few days later I recieved in the mail a brand new set of outdrives (they sent me HD outdrives not the original standard ones). I have to say Losi appears to be a company that stands behind their product and wants the customer to be happy.
