Hi guys my name is jr. I'm just getting into the hobby and bought my first rc off Craigslist today. Bought a stampede 2wd xl5. I don't think it is waterproof and is in like new condition. Came with 2 batts and a charger. What should I do to it first?? Also where is the best place to get upgrade parts? Paid 80 bucks for it and it runs great. I also plan on buying a rustler vxl on Friday. Any info or input would be greatly appreciated. Thanks
