Well as someone that owns 2 DF-02's its not a bad buggy if you want to put a lil bit into upgrades (and have tools to do some work)
Stock though its a tad slow on a 27T brushed motor, they take lower cost brushless motors quite well though.
Upgrades that are almost needed is the aluminum front shock tower (and one cut out of fiberglass or 3mm aluminum to be placed on the opposite side to reinforce it), some piano wire to make longer "forks" to hold the arms on(stocks are short, and cause the chassis to break), shocks, and ball bearings as the bushings suck.
Too bad ofna canned the CRT.5 line that would have been perfect
