JUST WONDERING IF ANYONE HAS AS MUCH TROUBLE WITH THE DIFF GEAR IN THE EVADER NITRO AS I DO. SEEMS LIKE EVERY 10 RUNS I STRIP IT OUT. I TRY NOT TO RUN IT TO TIGHT AND NOT TO LOOSE, BUT ALWAYS THE SAME THING. I MEAN IT MELTS THE BALLS INTO THE PLASTIC. IS THERE A METAL DIFF GEAR OUT THERE. I HAVENT FOUND IT.WHAT DO I DO. I BUY THREE AT A TIME NOW!!![:'(]
