So the Infinity brush is better for power AND logevity? Because if thats the case, I would rather pick some up now, before I ever go out and run the motor.

Ran one last night for the first time in and FK04 on the dirt oval with 63mm tires. Started the same as my Reedy QM, a 5.87 fdr, it needed way more gear. We ran a 5.48 in the main and still think it needs more than that. Motor came off cool and still had great punch off the corners, I think once the gearing is right, it will be really good. The infinity brushes might not be as fast as the atlas brushes, they are a lot harder silver brush, may not be that much of a difference though. If you get 10 runs out of a set of atlas brushes then for 30 runs if would cost you $12 (3 sets of brushes) vs. 30 runs from one set of infinity brushes would be $10, so not that much of a difference

plus you also are better off with the three new sets of brushes as i always find a 'sharper' feel with new brushes.

Since there seems to be some debate as to which produces the most power, I guess I'll just stick with the Atlas brushes for my first outing next weekend. And play around with the gearing to see what makes the motor run best for our small/medium sized indoor carpet track.

Very good idea...should've taken your own advice in the first place O'Donnell came thru with this motor; I've used it for two days now and the motor rips (and I run it in my 12th scale) Coming out of the corners-YIKES!! Leave the Atlas brushes in (just gear correctly),the Infinity ones are optional 'hop-ups'

OK -- Managed to pickup a "money" 19t at the LHS... Now I have a comment and a question...

COMMENT:
When seating the brushes, the motor seemed erratic... Then I tried to dyno it on my TD45 (@ 7.0v for Offroad 6-cell numbers)... REALLY erratic -- bizarre readings (RPM readings Way low at some readings, normal at others, with no pattern to it)... Pulled the motor off the dyno, pulled out the brushes and found fine copper debris in the hoods was hanging the brushes up... Cleaned the tubes with a Q-tip and solvent, cleaned the brushes and the comm... Back on the dyno -- Very normal, no more issues, GOOD numbers... Probably a one-off manufacturing or assembly issue at the source, but I thought I'd mention it -- "no harm, no foul" for me -- motor is fine now....

QUESTION:
Given the brush hang problem, and that the brush springs are (I believe) soft to medium in stiffness -- should I try stiffer springs for OFFROAD? The local indoor offroad track only runs 19t and Mod, so I want to try this motor there in my MF2 truck... With the vibration and landings (some big jumps), I now wonder about brush springs, but hate to change them if I don't have to...

Checkpoint didnt design their motor for Roar rules as it will never be used for a handout at a Roar race anyway. They vent holes on the side of the can do not meet roar rules either (another stupid rule on Roar's part). When I asked Dewayne about it he said that he had spoke with Roar about the vent holes before they decieded on a hemi wound arm and Roar said that they would NOT legalize the motor like it was with the vent hole being too close to the end of the can. And Checkpoint was NOT going to redesign their entire can just to make Roar happy as it is the same can as the Mod motor other than the notch. So they decided to use the Hemi wound arm as well since it will be competing agains the Reedy motor head to head on the track's as 99% of the tracks in the country do not use Roar rules for the 19 turn motor rules.

Thanks Eric. I agree that most tracks only care the motor is 19 turn tagged arm and locked timing. I just thought I read that this motor was being submitted for approval. I wish ROAR would get their act together on a sensible 19 turn rule

Thanks Wallstreet We ran a couple packs through it at Trackside Friday night.... same layout as the Hurricane Series race.... Power looked good... we rolled it out at 1.26... seemed pretty close.
