Plenty of fancy extra hard silver ones though. Which begs the question... why didn't they make the comms out of silver. Maybe I should electroplate my comms? I suppose that would help them last longer?

He suggested that comm drops would only accelerate comm wear and are marginally pointless for races longer than 3 minutes. He suggested just running them dry.

We also spoke about break ins as well. He only broke them in dry on his car. He said that the water method was only for motors without ball bearings and was only to break in the bushes. Any truth to this?

I'm still no closer to finding a magneto charger either (magnet zapper)

Yes, the water method is for your brushes it also puts a shiny coat on your com. A silver composite com would be ideal but expensive as mentioned above .there is nothing you can do to stop the wear. that's just the way it is.
