The outer rear hinge pins are the ONLY thing that I would say have a problem. I've had my 8 since November. I stopped counting gallons after 10. I'm someware in the 12 to 13 gallon area now. I have bent 3 rear outer hing pins (hitting a fence parralel to a high speed jump). I've bent 1 inner rear hinge pin (same fence). I put NO lube of any kind on the CV joints & they are all fine. Not counting the clutch, I've had 1 bearing fail (outer rear hub on the same side as the damaged hinge pins). For reliablity I would put it up against my Mugen any day. The guys who say "I hear they have this or that problem" are talking with no experiance. There is no servo issue on the kit. I'm on the same servo I put in the day I built the kit. The only thing I did that was not called out in the instuctions was cut the return spring. I think Losi's biggest problem is that a lot of people who have never owned a buggie got the 8 & do not know how to set it up properly & do not know that these cars (all brands) are not indestuctable. This week end I had my first "major failure". I stipped the rear ring & pinion. No Big Deal.
