from the soundss of that, you had the spiral wire resting against the motor endbell yes? so the solder tabs on the motor melted into the plastic when the motor was hot?
This may not be a huge problem as brushed motors do get pretty hot when thrashed around, and if the plastic has a pretty low melting point then that could explain it. The way to spot a major problem is as previously said the motor wires unsolder themselves, or if you notice the performance of the car drop off considerably.
Check what gearing most club racers use for your car as a good starting point. Run the wires so they don't actually touch the motor. And try and improve the air flow through the shell with cut outs in the vents and make sure there is a cut out at the rear to let the air flow out the back too.
You can also fit a small fan in the car to blow air at the motor if the problem persists.
