I've run just shy of a gallon thru mine so far. I really like this truggy. Lots of fun. I did pull the shocks and flushed then refilled with 50wt. The rear shock came preloaded with 1 thick space and none in the front. I added 1 more of the thickest to the rear and just 1 single thick to the fronts and it handles really well. Flies nice and level, lands nice.
Main area of concern is the amount of slop in the front end. I did replace the steering bushings with bearing even before I ran it once. But lots of minor slop in every joint/knuckle etc. all adds up and wheels almost feel as they are falling off. The toe can change as much as 3/16 of an inch from in to out...that's way too much. I noticed that it does want to wander a little. I will investigate and find a fix.
