The Dyno labels that come on the motors are generally considered to be of little accuracy. I would try to find an Armature with the least amount of balancing done to it. This seems to make for a little more power. In my Dyno tuning on the Monster Stock, I have found that Red springs on both terminals provide an increase in power and torque with a very slight reduction in RPM. Trinity #4499 or Reedy #767 and similar compound brushes seem to work best.
As for overall power, torque, etc. It really is a matter of luck when picking motors as to which ones are better. Gearing is very important to get these Motors to perform at there best. A starting Final Drive Ratio of 7.5 to 8.0 should be good. Adjust from there based on the size of your track and how the motor feels.

Trinity red springs on both poles, and Reedy 767 on (+) with Reedy 766 on (-). I've run the 4499's, but it also depends on the track.

For 1/12 4 cell on carpet, the 4499 or 767 with a vertical slot and very slightly narrowed with green springs on both seems to be working well around here.

What's recommended brushes + springs for the monster on a tight carpet track about 40x75 with two sweepers (no real straights) about 45-50 feet long? Also what should I start gearing at? (final drive) As you can see by my sig, I'm driving a Losi XXX-SGP on rubber. Thanks for the help!

I usually run trinity green on neg, red on pos, axiom 12 full 5 serr brushes.

ski- gear it at about an 8.5, you will have plenty of rip with all the rpm this motor has.

Thanks Stephen on the gearing recommendation. I can't get Axiom brushes tho! What would you recommend out of these three:

-Fantom 315

-Reedy 767

-Trinity Crosscuts

Thanks again!

I ran some 4505's this last weekend. I was very impressed. The motor had plenty of torque and rpm but the comm wear was much less than I have been having utilizing 767s. I usually get one run before it is time to cut the comm but with the 4505's I got two runs and only had to make one pass with the lathe. The brushes still have serrations too!

Steve, if you are still running trucks I would put purple springs on it. The motor has a lot of rpm and not as much torque as some others. You have a lot of tire there to get up to speed and the heavier springs will bring the torque back.
