You can achieve a better result if you use 2 of the one shown on picture DSC_0705 because it can ensure a correct angle of the point of contact with the commutator. That is, if you buy one pack of ATX brushes which contains 2 pairs, you use those for the positive pole. The negative brushes can be reserved for later use because the tip of the brush can be removed and replaced.

Do you mean using both positive brushes? can you elaborate more? thanks

You mean take the 2 positive brushes from the 2 pair of brushes? Then put them on positive side and negative side on the motor?
Your first question: Yes, I meant that.
Your Second question: What do you want me to elaborate?
elaborate on how does this help on the motor's performance? I mean the correct angle thing?
and on how will the brushes looks like? do you have any photo? coz I wanna try it~ thanks
Exactly. Of course you have to solder the wire to one of the brushes on another point.
Oh! That's what I am doing already! When the brushes wear out, then u can take the brushes off from the spare -ve brushes....then put them back onto the current +ve and +ve end....

I see, just what I'm expecting to see, brushes in a "69" position... thanks
how about the magnets? any twist or tricks on the magnets too? Specially in relation with the brush trick
Not much, just 2 if you are using silver magnets:
1. They can be weakened if overheated. Sometimes I prefer weaker silver magnets if the straights are long.
2. If the magnets are not strong enough, add some double-sided tapes between the magnets and the motor case to reduce their distance from the rotor. It raises the torque to a certain extent.

Thanks Billy for the tips and answering my doubts...
1. trying to figure why the weaker magnets for long straights, is that it provides less drag? sure it does affects the momentum of the car but then the torgue could be lessen too, right?
2. Mmm.. I should try this one. by the way, I'm not sure if the 2 magnets in the motors have different poles, how about reversing the magnets? does it helps?

Reversing the magnets without doing other things reverse the spinning direction of the rotor. People do that sometimes because they "re-wind" the rotor in another direction. Most motors sold are winded "anti-clockwisely", so the red magnet is usually on the right if you remove the endbell and look inside. So if some winds the motor "clockwisely", they may either trade the position of the magnets or the wires.

Mmm..so it merely reverse the spinning direction, no improvements on the motor..
