It also had a black capicitor soldered inline on the leads. All that seemed wierd, so I soldered new deans wires to everything, but I was wondering what the capacitor and funny wiring was for?
I hope that makes sense. Also, does anyone have any good recommendations for an asphalt setup. There is a local track at hobbytown that I would like to get into racing at.
Lastly, I was wondering where I should order bearings from for the rc12l4. One of my front wheels has alot of wobble and a couple of my diff bearings are shot.
Thanks.
How are the 3 solder points on the GM ESC labeled?
For a QC2 (with 3 solder points) the "MOT+" goes to the plus side of the battery AND the plus side of the motor. You can "T" off of the motor wire to make only three connections at the ESC and minimize the amount of wire needed.
