RE: need info on ta-02
ta02's are tougher then you'd think. they are based on the df01/ta01. i have a df01 4wd buggy with a brushless system, the only upgrades i needed to do was an alloy prop shaft and cvd's.
just make sure the parts you buy say they'll work on a ta02 as they aren't as long as the df01/ta01.
