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.

Have you seen how big the are??? Yeah .0020" is just too big to have the motor approved. I see why ROAR wouldn't approve it...NOT!!!

Yea I know Fred....Ive got some sitting in front of me...Im not bashing Checkpoint...I do not blame them. I would not change it either.... I was just stating why they would not be roar legal and what Duane had told me.

There's no need for a third. It will be fine.

FYI/Update...

I ran the "money" motor in my MF2 during a practice night at the local indoor offroad track -- it's a BIG track, with lots of big jumps...

With the stock springs, the motor seems to have allowed WAY too much brush bounce. geared conservatively (based on other motors I've run and on TD45 RPM readings, etc.) it only took two (2) practice runs to turn the comm that nasty purple/gray color that shows bad brush contact. the portion of the comm outside the brush track was that red/brass color that indicated over heating. The motor also had the odor of excess comm heat...

The stock springs appear to just be too soft to handle the vibration and hammering that offroad produces. I have the stiffer springs to put in (Medium/Hard Silver), so we'll see how that works...

This in no way is a "slam" on the motor -- it ran strong and never faded on the track during these two runs, it just was very "unhappy" in terms of temp due to the brush bounce...

I gave my Money Motor a run this weekend in my sedan on a medium sized carpet track with foams. Heres what I found:

-First I noticed that there was a lot of arching on the comm by the positive brush. This was as I was breaking it in. I thought it was a bit much, but I wanted to run it as is first.

-My first run with the motor, I geared it at about 6.13, which is much more conservative than the 5.8 many people mentioned here. The thing was ballistic!!! The top speed was a bit much for the track, but it was clearly a fast motor. The temp coming off the track was 140 degrees. Hotter than my C2 motors, but there seemed to be no ill effects

-After about 3-4 total runs, I wanted to open the motor up for the first time. First thing I noticed was that there were no balancing cuts on the arm, so I hope that just means I got a perfectly balanced one without the need for adjustment at the factory. There was some burning on the comm, obviously from the arching I first saw when I broke in the motor. I cut the comm on my Cobra lathe and found that the comm wasn't cut perfectly flat from the factory.

-So I cut the comm and rebuilt it, broke it in again and gave the brushes a chance to reseat with the newly perfect comm. After that, the arching was gone.

-Motor was very smooth and the comm showed no more signs of burning.

*The higher running temp doesn't seem to have any effect on the performance, the motor didn't soften at all during the 5 min race.
*I expect that with rubber tires and on a more flowing track, the temps will drop a good 10 degrees at least. Carpet racinig (with the high traction and heavy throttle usage) is tough on motors.

*I'm very happy with the motor. I do plan on trying the Infinity brushes and maybe some different springs.

Very worth while purchase.

Default If you want money motors...

www.jphracing.com, call or place an order online. Dont mean to sound push but we have more then anyone. Over 60 still left in stock. Just in case some of you are still having a hard time finding them. Ask for jake or dave.

For those looking for a good setup for the motor try:
Silver springs on the pos, and neg.

The only time I run o-rings in my motors is if I am using brakes, so I ditch all that stuff. 1 0.020 shim on the bottom of the arm shaft and then what ever it takes on top to shim out the slop. At least 0.005-0.010" endplay is still needed.

Drill a #56 hole in each brush. Clean the brushes with a fiberglass style comm stick, faces, all surfaces that contact the hoods... Dont use motor spray on the brushes. IMO it just makes the brushes arc more. Dont use comm drops.

Clean the hood with a q-tip spinning in a dremel. You can also use some contact cleaner on it if you run the motor a lot. It seems that these motors mod or 19t, are very dependent on good brush - hood contact and if that is not clean enough then you will see power suffer as a result.

Break-in the motor for at least 5 min, at 1.5 volts or what ever you like, w/fan. Let it cool then run it, or dyno it, or do what ever you want to do to it.

Approximately how big in inches is a #56 bit? 1/16" maybe?
