Basically, Team Associated craps all over whatever you have

I own:
RC-10 (practically indestructible and will eat your face with a good modified motor)
RC-10T (based on the above with a better transmission)
Tamiya Blackfoot (piece of crap ABS plastic R/C model. Tamiya made their mark in the industry with cool model designs, but performance/durability suffered greatly. To truly see your Tamiya model perform you basically end up replacing EVERYTHING with aftermarket parts).
