Our OEM supplier and contact is Finish Line like mentioned above.

You can get the Fbrushes from most of the top Comanies - EA, Br00d, Axiom, and others I am sure. We just got 600 pairs in.

I believe EA helped with the compound

The F brush is made by a brush company in the US for Finish line RC. The compound was developed by Rick, myself and a few other racers.

You can contact me via Email for OEM sales as Rick at Finish line doesnt deal with the OEM guys unless they meet the minimum order which is very large and regular.

Some brushes produce more Torque while others produce more RPM's

Some produce wide Power Bands and others produce tight Power Bands

Than there is Springs, comm size, timing (if adjustable), etc...


Basically any change to a motor could effect gearing... Ask the fast guys what they run and work from there.

Default Example

Fbrush on a Atlas produces more RPM - around 2k more on a TD45 @ 15amp load


Oval is a creature on its own - no offense. I will see if my Oval guy will come on here and help you out.

Hi,I am from Axiom, Dave asked me to reply to your post I run alot of dirt and carpet oval gearbox, both car and truck, I have run the f brushes for some time, I have used them for stock in the cobalt motors f brush on the positive side and on the negative side a 4499e brush, on shorter tracks springs were purple on the positive and red on the negitive, this usually builds a good bit of torque, but watch the gearing, this builds alot of heat also. to gain more rpm, just drill a hole in the center of each brush,change to a red spring on the positive and a green on the negitive, and drop a tooth or so, for monster stock I use putnam green shunt on the positive and blue shunt on the negitive, a red spring on the positive and a green spring on the negitive, also drill a hole in the center of each brush and remove a very small amount off the leading edge to increase timing, I hope I have helped you some,These combinations have worked very well for me, Although alot would depend on size of track and type of car, ie, pan, or gearbox,A rule of thumb, what ever gearing you ran with the monster stock, drop a tooth at least with the cobalt and it will really come off the turns with authority.
