I got a clone... King Motors X2, runs strong... BUT you need to replace all diff internals to Losi at some point.
Had some issues, many could have been prevented if I would have done more research on YT, and on large scale forums. I ended up doing all the preventive measurements most recommended, after the fact.
So far, its a beast with a 30.5cc stock engine.
Radio system works very well, no issues, chassis, and all plastic parts are of very good quality. Like stated losi diff internals, proper oil, locktite and done.
