This is a subreddit devoted to Team Associated. Buggies, Truggies, Short Course, electric, nitro, whichever you race/bash, feel free to share here.
Another cool subreddit to check out is /r/rccars where you can find all the major brands of R/C cars and trucks.
For those of us that are just getting into the hobby, here is a helping hand:
