Well, I bought this car used, in very good condition, but the motor seems to be failing. Under power it only turns a quarter-turn at a time, kinda sputters and I can see it light up and spark on the inside.
It spins freely by hand, like normal.
Can someone recommend a contact cleaner for me to try to clean it with - perhaps CRC or DeoxIT or Techspray ELine Contact Cleaner? Also, are there special tools needed to take it apart if I need to do that?
Here's the car in question, fwiw. Thanks!
