Lots of choices out there:
Kyosho
Xray
Schumacher
Durango
Losi
Yokomo
Think everyone had a car in the A with the exception of Durango. I love Schumacher's quality. That being said, they sure have released a bunch of cars the last 3-4 years. Yokomo has always been top notch and Kyosho has a cult following. I just ordered an RB6 because I havent raced a Kyosho in over 20 years and figured, why not? I'll probably grab their 4wd as well since my Cat is fairly old (only run a few times in the 3-4 years I've owned it).
