heres a few, there is a rod that keeps the wheels straight in the back and when you land hard hard on the rear bumber dead on off a jump it bends or pops off so the wheels not straight anymore. get it in titanium from lungsford racing on their website. the plastic spurs are going to strip so a 49t spur gear (metal) is essental. if you land a jump wiith throttle on, 1 of 3 things will occur, either the dogbones, differental, or wheel will strip out, if the diff has the 4 spider mod then the wheel will probably strip so be ready to buy another rim. a roll cage is nice to bulletproof the truck, its a bashing need if you get a rolol cage thats not rcsolutions then your an idiot (like me). go to rcsolutions and look at the roll cae for the savage, very very very durable and makes your truck look good and unbreakable, the arms are so think that those arnt needed to be in aluminum. this is really about it. email me if you need any more pointers at
