Any idea wher to get....There is one at TCSS Hobby but its not for sale.
I think Asrah has one!, BTW why need a serrator lah? just get those serrated or profiled brushes will do, will save a lot of troubles!. The carbon brushs will crack if it is not done properly.......My 2 cents worth!

Rudy: You can get the brush serrator from Hobby Paradise (Tay's Shop) or Rotor hobby.
The serration on the brush is just there to help the brush break in faster, it will not make the motor faster, in fact it will be slower, until the brush fully sit in.

Less brush contact = less amp draw = less rpm
Thanks for the info, I've gotten the brush serrator and somebody told me it would increase RPM..... Could I have heard wrongly.... daMN&^%%$%$

Really? I was told that when you serrate the brush, you get more power at high revs (hence higher top speed), but less punchy. The motor draws lower current and runtime increases.
