Sorry about the name thing Korey.
Anyways, as to the wear on the 19T motors, I've heard many different things. Some people swear their motor runs best after 10 runs after the brushes break in. On the other hand, certain brushes I've tried have turned a comm purple in 3 runs
One more thing to anyone who is just starting their 19T racing is don't judge a 19T by the brushes it comes with. Motors like the Reedy (I think) come with really hard, low power brushes which can actually make the motor slower than a good stock motor. On the other hand, the Fantom I believe includes the 315
and so, these 2 cannot be compared out of the box erm... plastic case thing.
