springs - red/red
brush - F-brush seems to be the most popular

here's one from duratrax, $9.99 at towerhobbies

http://www2.towerhobbies.com/cgi-bin...?&I=LXKAE2&P=7

integy also has nice ones in the $30+ range, they have aluminum bases that stand on your pit table while cutting brushes. the most expensive one at about $50+ has a serrator and a cutting disc for slotting brushes

here's a pic of the duratrax brush cutter...

I don't think these brush cutters are really worth it or are they? My motors seem to perform better full faced broken in than serrated.

I am sorry, but are serations mainly just to allow the brushes to seat in quicker, That is what I was told, and it made sence. Sorry I am trying to figure out all this motor stuff. Thanks.

so then what is the difference between strait cut serations opposed to angled serations on a brush? just my thought serations take away serface area of the brush so how does that increase

. would more serface are not increase the amount of amperage the motor could draw?

If you want do increase-timing cut, you need something like this from MuchMore:



See the different shape? They are for increase-timing.

No ,not in 27t/19t spec
with these motor`s power from comm to brush is more important to abtain
you need the edges for the power to transfer better/quicker from comm to brush

I had both the much more and the duratrax brush cutters shown above and found that the much-more was better, as stated the timing was changed and the power transfer seemed to increase. But I have misplaced my much more cutter and have only been using the duratrax and can't get more that a 9-10 amp draw from the duratrax cuts after break-in and seating the brushes.

I need to stop looking for the much-more cutter and break down and pick up another one. I have been sacrificing the amount of power trying to believe I will find it. BUt I know as soon as I buy another one it will show up mysteriously like all items we think are lost.....

Wouldn't the brush hoods have to be moved (offset) to make these brushes fit the comm. ? If so, isn't there a rule (roar) that prohibits that ?
