CAn you see anything when you look in the vents on the motor? I remember running an off-road truck w/ a brushed and getting a stick stuck in one of the vents. It was a tiny piece of bark actually and it jammed up my motor ...I was able to get it out w/ tweezers ...but took awhile as it was lodged in pretty good.
Thank you very much!

I didn't see anything through the vents of the can, that's why I wanted to disassemble it. I found a small piece of iron wire (or something like that) between the rotor and one of the magnets. Probably it went into the motor through the vent, because rotor coils aren't damaged. Tomorrow (here it's midnight at the moment) i'll bash the car and see if problem is solved.
