Spent the better half of my Sunday cleaning the motor used on my Stampede. Actually, I didn't really want to do it, but I was forced to since my motor wasn't running as well as it usually does..
After two hard years of abuse, the motor finally said it's time for a cleaning.. and boy was it right!
The following is a quick poke at the positive magnet inside the can. Ever wondered what happens when a motor gets really hot and burns up/off the comm. drops? Well, it turns into a horribly sticky and ugly black substance. Fortunate for me, I was already wearing black shorts to wipe my fingers on.
That's how dirty the inside of the can was...
And just for kicks-and-giggles, here are two comparision shots of a 540 wound armature next to a 130 blank armature.
The 540 armature is an Epic 17 double turn armature. The 130 is obviously blank.
