The people that are having issues with their diffs... and be honest now.... Do you use that throttle/brake as an on/on switch? Your either on the 100% gas or on the brakes? Just curious.
I got my 8ight used. It does not appear that the diff housings were ever replaced. I've put 3, almost 4 gallons on it... to the point the chassis is nearly wore out from myself and the previous owner... and I haven't had one issue with them.
I have my 8ight T... not nearly as much time on it... 2 race weekends... and no issues there either. But I'd hope not with how little time I have on it.
I really dont get the guys that bash the Losi. All year, I broke 3 tie rod ends, one inner hinge pin. One servo in the beginning because I didn't set it up right... not because the car blew it up. Two of those parts were because my receiver batt went dead and the throttle pegged wide open. Vspec stuck wide open hitting a full size parked car = broken parts on any car.
