Ran this by my son as he is big in to these and he had never heard of doing this. 

Trinity used to sell a little bottle of break in drop that you dripped onto the brushes. 

 

Found it....

Trinity Motor Drops link

Read the product description for details about how to break a motor in.

Thanks but I don't think I will buy anything more for this truck because I am already spending double the cost of it on upgrades. Ill make a post about it soon.

Nice didn't know that, we will have to talk sometime. Basically, making the motor better for use makes it faster and more durable by getting gunk out and shaving the blemishes away on the inside brushes.

He may be only brushless which is the next upgrade for me.

I used to race at a national level.  Never heard of breaking a motor in other than oiling the bushings.

 

Run that thing as hard as you can and then use a fiberglass stick to clean the commutator.

Water. Hook it up to a speed control, and submerge it completely 0into a glass. Secure it. (I like a pair of channel locks.) Run it till the water gets super cloudy. Take it out of the waterRemove the springs and brushes.  Blow out the water with compressed air. Oil bushings/bearings.

It's now broken in.

That's out if like 1991!  I remember doing that.  

However, using a dyno says all that does is start getting water in all the crevices.

I had a little rig to spin the new motor with an old one to bed the brushes without running voltage. It was supposed to help. No clue if it did, I always crashed on turn 1.

You make a good point there.  The first time you really hit something hard usually makes the brushes bounce on the comm and then it needs polished back up and cleaned back up to work at its peak.  

Not always, but I've seen it enough times and experimented with enough motors on the dyno to see that it happens.
