1) Does anyone know a good page where the different brushed motors can be compared? Further I don't know the different purpose of the motors.
2) Is Tamiya replacing the black Sport-Tuned motor 53068 with the silver one now (see pictures)?
I would like to know if some unused Tamiya paint stored in the original spray can has something like an expiration date. I mean a date you shouldn't use it any more because of bad results by painting?
