I haven't used my emaxx in about 18 months but i decided to run it yesterday. I used two new 3s lipos and a took it for a test run after just 3 minutes i started to smell something burning it was a horrible smell like when roads are freshly paved. It seemed to be coming from the slipper clutch. so my ? is what is the best way to set the slipper? its been awhile since i have tinkered with this thing and i can't remember?
