Looks like you have a lot of pictures to post tmaxx! They're not radio controlled cars if a radio doesn't control them.
I currently have a 2.5 Maxx(foc, brand-spankin' new rear bulk from Rc boyz, 3.3 tires, '72 chevy body). Original E Maxx upgraded to 3.3 spec from the diffs out, modded 550's, Team Losi Raminator with a lipo, Stampede with xl5 and Duratrax nitro mt tires(about 5 in. tall), Rustler with ez run b.l. system that the motor gets hot enough to fry bacon, A broken Rc10gt and a Blackfoot without any electronics. Oh, I almost forgot about my pride and joy... A 1988 ultima 1/20 scale with the original 230mah 7.2 nicd's! Look out!
