I saw that buggy too. All the bling came from Yeah Racing. It sure was heavy. Maybe an extra half a kilo. The shock towers looked as thick as the ones on 1/8 buggies.
ganaz-x, I have not built or run mine but I heard the diff cup damage comes from the dogbones popping in and out of the cup on full steering lock (maybe full steering lock in conjunction with full shock compression or extension). The DF-02 upgrade CVD/universals work perfectly for the DF-03 and should help the problem.
proceed5, haha here's my plan. I'm busy until January so after that, maybe play at Chee Yong's track and get him to set up the buggy ramp once a week (like M-chassis but different day lah). So you can wait and get the buggy later lah. Who knows, maybe you want to get the TRF501X leh. Heheh.
