I bought a Losi xxt from someone here on RCGroups and guess what... it didn't work.
We found out that the gears were shot, the chassis brace was broken, it was missing 3 E clips, the front bumper, the body clips, the dust cover, and the wheel caps.
We ordered the gears, bumper, e clips, and body clips from a website. they do not make the dust cover, the chassis brace, or the wheel caps anymore though.
Later we found out that the differential was messed up so we had to fix that.
We found a carbon brace like the original one.
We bought a dust cover for a different car and made a mold from it then vaccuum formed a new one that fit.
We still need to buy a new battery for it.
The funny part is that the guy said that it was RTR and that it ran perfectly.
That was a HUGE lie.
So far it has cost an extra 30 dollars and we still need to buy a new battery.
