Cool cars!... If you go on the R/C Graphy part of the forum, look there and you will soon find the names of people who can paint you some really nice shells! blitzboy, jonmiller and telboy to name a few
the one way bearing setup was used in the X10, i havent tried it in my X11 yet, but i like the car how it is at the moment, without it.
Northy or Nathan are probably the best people to speak to
