i've wanted to know this, what is the purpose of cutting a brush(a new one). Or is this just for used brushes.

do you have a dyno? Or can you borrow one?

I'm asking the same questions myself, but I just got a used fantom and have been experiemting today.

LEading edge cuts will increase efficiency but decrees power. Horizontal cuts will increase power, but at a slight cost in efficiency. Same with drilled brushes. Trinity high silvers are slightly better than 4499s, but wear faster.

Lighter springs seem to work better, but In' not sure if that will translate onto the track. Find out this weekend.

But from a couple of hours of playing around, having your brush hoods aligned is by far the best tuning you can do.

Do a search on the net for "Big Jims Motor Black Book" you'll find everything you could ever want to know about motors in that. Or buy the actual book on the Team Paradigm link on my signature.
