Well, it's official now, I REALLY LIKE this motor! I'm starting to think it's really everything Trinity said it'd be, for a change. It doesn't quite have the top end rpm of a Monster, but it MORE than makes up for it in raw power & low-rpm torque, & the efficiency seems to be there, too. On our med-small track, I usually gear my Monsters at about 8.00:1 final, so this one I started at 7.5:1 & it felt good, plus it BARELY even got warm at all, through both the practice & first qualifier(& after those 2 runs, the comm looked pristine, like it'd barely even broken its brushes in, though they were already broken in), so later & geared up to about a 7.35:1 & it felt even better, with NO change in temp. or how the comm looked, & I finished the night that way, & even turned 2 personal best runs in a row(& personal best laps for that track layout). And still after 4 runs, the comm looked EXCELLENT, again like it'd hardly been run at all. I get the feeling I've barely even scratched the surface on gearing this thing right, & it's already running that strong. All in all, it was an EXCELLENT first night with it, & I'm looking forward to playing with it a LOT more.....

I too had gotten a plain CO, just to play with, as my tuner was out at the moment... all i did to it was retrue, check the shim center, and put F's on it with 2 purple springs.
im no motor tuner by far, but it didnt really work well till i had ran it in for 2-5 minute no-load sessions, and in the car for the 2nd run. seemed to wake up more and more as i ran it. my gearing was at 6.65, on the same track as Griz above.... roughly 4 (!) teeth over my regualr Monster gearing. got a little warm, but not bad, plus the comm still looks great!

it was ran in @ 2v for 300 seconds, two times.
after puting it in the car, the first run seemed a little slow... the 2nd was a little better, but the third it really woke up. maybe the Fs want more time on this motor? i didnt really have a chance to try much, as i got to the track late...

Just my opinoin...
I dont have a Dyno.. so I have no numbers... all I have is on track feel.
Right now, I'm running a purple/red spring combo with 767's. (of course with all the little tricks before hand) Break in for 4 minutes @ 2v with Tribo drops, no fan. Blow the motor out with cleaner... another drop or two on the comm of tribo.. run the motor for about 30 seconds to oil the bushings up. Then I knock it up to 3 v to see what the no load amp draw is. For me, the motors at this point are normally in the 4-5 amps. Go out and run... once geared to my liking the motor is at about 140 degrees and just plain RIPS. I have found one motor that I like much more then the other... but I plan on buying a few more, so I hope to find a few more "good" ones. This setup, combined with a Tamiya 415 MS netted me the 3rd fastest lap of the A last tuesday... 1 and 2 were by the same guy.
Next thing I would like to play with is spring tensions but I have to pick up a spring dyno... anyone have any recommendations?

Here's a tuning update on a few different brush combo's tried and dyno'd on the same CO27 from a few posts above. If you recall, I missed the mark on centering the can during the first magnet zap, since the shimming was completely biased toward the hood end. Therefore I re-zapped the can with the magnets better centered in the zapper, re-shimmed the arm (much better magnetic field center this time) and skimmed the comm, before making the following dyno runs. All the brushes were new, except the F brush combo which were the same brushes used before.
