My Revo chassis keeps bending slightly right by the engine causing it to tilt foward and changing the gear mesh as well as contact between the spur and intake boot. Ya sure the picco .26 is probably the cause as it does weigh a little more but it runs way too good to consider going back! I was wondering if anybody has tried the vantage carbon fiber chassis and actully tested it in full race type enviroment, if so let me know becuase I'm thinkin SNAP :shrug:
