Hey guys i have 4 of the Slayer pro 4x4 and i have had nothing but trouble with the one way bearings on them not working correctly. Is this a common issue? I have already go through 3 of them and they arnt cheap I have tried cleaning them and everything. I also put new starter shafts in each time. What makes it start to slip so much so fast? I only had maybe if im like 3 hours of running on the last one before it gave away. I just dont get it and hope for some help if you all would be willing.
