Help.. BL setup issues (fried ESC)

[xcntrk]

Thanks aqwut!

Good news, turns out the ESC isn’t totally fried! I re-soldered the motor lead that came off, powered it up, it engaged and operated normally on the work-bench at least. Still may be some damage from the excessive heat it was subjected to. How can I tell if it’s got some burned up fets?

I’m thinking something must be wrong with my drivetrain. I keep swapping around my tire/wheel combinations and did put a new (previously unused) set on before this issue. Looking back the rig was pulling slightly to one side which I didn’t think was too unusual at the time. I had to counter with additional steering servo trim yet I hadn’t touched the steering linkages with my recent tranny rebuild and gear changing. Now I’m thinking one of hubs or wheels was dragging for some reason, possibly causing the pulling to one side and elevated load on the electronics.

I run the UE 6mm CVD shafts and don’t like the hub/hex setup. It secures to the axle using set-screws (instead of hub-pins) and it seems this special hex can slide all the way firm against the bearing/hub-carrier. So when you crank down your wheel nuts, the wheel seems to be pushing against the hex, and the hex seems to slide down the axle shaft and tight against the bearing/hub-carrier. Not sure what’s up with that….
