RC Buggies or cars anyone?

[e-man67]

My sons 10th birthday is this Friday and I wasn't sure what to get him. He really doesn't have any interests (plays sports b/c we ask him to) besides video games and even then he only plays Mario Cart on Wii and DS. So...a few of his friends race these RC trucks so I figured since he likes driving games maybe he would like driving a RC car. I know nothing about them but bought him a Traxxas Slash model brushless 4x4 with a 5800 mAH lipo battery and charger...I hope the heck he likes it b/c it cost me a bunch of coin...I think I am as anxious as he is. I like working on cars in my spare time so I am hoping he will want to learn a bit of mechanics working on his RC car. So anyone out there do this sort of thing and can offer any advice?
