I`ve been running mostly outdoors and the only thing i did was change the rear schocks to 35 weigth associated oil (thats what i had ) the rear was bottoming out big time on the woops and the big table top , now seems good but still need to do more dialing in , love the truck also guys do yourself a favor change the rear hubs to alluminun they look great and will handle anything you can throw at it , i snap my stock left hub on my fourth run I will never run the stock rear hubs again way to weak , you would think losi would had throw that in the kit , oh well
