The Associated B4 is one of the top two supported buggies for racing (the other being the Losi buggy), but if your local shop doesn't have much support for it you are likely better off with a different choice that your local shop DOES support.
Although the Jato does have the opportunity to mount the motor in front of the rear axle, that also cuts into the room you have to mount other items. Also, when I converted my Jato and raced other electric stadium trucks, I'm pretty sure the Jato was about 1 lb. heavier than the others. This has quite a bit to do with the extra weight of the transmission and aluminum chassis.
A 1/10th scale 2wd electric buggy will give you the smallest, lightest 2wd form to get you started, so that would be what I'd advise.
As I initially stated, though, your best bet is almost always to own things that your local shop supports. It will help out the shop owner and yourself at the same time.
Keep in mind that if you can't find it in your local shop,
