I just picked up this HPI S2 flux and im having a blast drifting it in my garage but Ive noticed a few issues im trying to address . Im sure this has been covered and I tried to read the whole thread but I didn't see what i was looking for . My issue is that my tensioner bushings seems to be real sloppy and I wanted to replace them with bearings . Has anyone done this and if so what size bearings are recommended . I think I'm going to do the extra tensioner mods as well but 1 thing at a time .lol. Thanks
