Hello everyone, I work at a hobby shop here in town and I just read R/C Car magazine and was looking at the Buggy Competition in there and saw that the Mayhem was #1. I got a Mayhem RTR in my shop and looked at it. It does impress me but ive heard and read that the difs give this buggy some issues. So my question to all of you is what do you suggest to fix them or do they even need to be fixed. Also what do you recomend for dif oil? I believe that it was 3000, 5000, 7000, but i've never had a buggy so i dunno. One other question is what does the 053 Tuned pipe mean? what does 053 mean cuse i see that on alot of buggy's.

Thanks
