Uh... ok.

But, I really don't mean to argue, anyway. All input is good input.
Thanks.

I assume it's a 3 step MSC. Step one about 1/4 to 1/3 of the voltage gets to the motor, the rest to the resistor. Step 2 about 1/2 to 2/3 volts go to motor, rest to resistor. Step 3 all voltage goes to motor, none to the resistor. So the coolest time for the resistor is WOT.

yup same for your slot cars also you should be fine running since guys have ran MSC's for years and none of there old RC10's or Grasshoppers burned up. Just make sure your resister is away from thinks that can melt....say about 1/4 to 1/2 inch all around.
