i play with it outside so much, my tires are all worn out and i do donouts ;/...fun though

i sometimes race in my garage with smooth concrete for traction testing
if you arent skilled at soldering, i suggest you give it a try, its cheap to start...10-20$ worth of soldering equipment is good, and it lasts a while plus, if you want to add more battery cases, new motors, and other modifications like 2nd, third gear, etc...you HAVE to solder.
the range out of the box is friggin amazing....it comes with an antenna that stretches out at least 32" and it pretty much goes all the way down my street to where i cant see it...no need to do any range mods.
speed hmm...lets see....when im using turbo+2 extra batteries...i can speed walk/jog with it

..i need a faster motor
if you buy a wheel kit, it will come with separate knuckles for those tires, and allows you to add suspension springs because the knuckles are longer. you just pop the bolt in with the rim and should be good to go.
the stickers...haha that was THE FIRST thing i did. ...first peel as much as you can off, and then use some special cleaner called "Goo Gone" or WD40 ive heard works...then clean it with dish washing soap..and should be alot nicer looking.
hope that helps....
