Humm , See and i was under the impression the BIG selling point of the checkpoint motors was LOW maintainence..........

If they really want to push this as a major selling point which i think could work really well for them maybe they should include the Infinity brushes as std.

Anyways i like it and it's legal which is always a good thing

In this case runnning infinity brushes will cost less than putting new atlas brushes every two runs. But this also happens to my money motor atlas burshes is only good for couple of runs not good.

It's not slow, infact it has great punch and ok top end but look at the state of it after just 2 runs !!

Moving over to the "Mega Money" long life brushes now to see if they improve things at all
I've found that changing to stiffer springs helps -- I'm racing offroad 19t and the extra vibration requires stiffer springs to avoid excessive brush bounce.

Running stiffer springs will take some RPM away.

I haven't found this to be the case. I am running the stiffest spring CP cells with infinity brushes. I have tried softer springs and I dont see any increase in RPM. I do see more scorched comms with soft springs though.

Also...dont be afraid to run a huge gear ratio on this motor.

I think you want to run this motor just like the Orion Element V2, hard springs and enduro brushes, then gear it to the moon. I've geared my Element to a 5 FDR before

The motors like a big gear. When we tested the motors we always ended up with a bigger gear. The discoloration of the comm isn't anything to worry about. We have run 6-10 runs on a motor with the atlas brushes before we seen any performance drop off. This was with the stiffer springs.

Hmm...I guess two people on earth have figured out the Element V2 now I use MR springs with Sprint Edge brushes at 5.15:1 with the V2.

I don't run quite that much gear on my CP Money though. I run it around 5.4 to 5.8.

Adrian - I tried the money motor in my 1/12th scale and it seemed to me it had to much natural drag brake, kinda like a stock motor? I pulled it out and ran a c2 and it rolled much better off throttle. I even tried turning up the throttle trim to compensate but it still decel'd very hard, almost to the point of spinning the car out, what do you think?

Adrian, how about for 1/12th with the CP Money? Do I run it with a 88T or 96T? I'm running on carpet indoor.

might be the stronger magnets on the $$motor causing the dragbrake effect.

The sedan and 1/12th setups are diffrent. For sedan its heavy spring and Infinity brush. For 1/12th its light spring and Atlas brush. The Atlas is a more agressive brush that runs well with 4 cells. The lighter spring reduces some of the comm drag.

The best solution is putting in more roll throttle (Car moves forward at trigger neutral).

Yeah, Trinity uses "Stock" level magnets to get more RPM (because RPM sells). They have less cogging and thus less drag. But in sedan they fade if you run them hard or run on really hot race days.

Everyone else uses the same magents as thier Mod motors. They have more cogging and generate a ton of torque. This is why Money's, Reedy QM19's and Orion 19's can swing the really big pinions. These motors are pretty much not affected by heat.

Do you recommand to use a motor cooler for the CP Money before a run though? Or does it not needed at all for 1/12 4 cells 19T racing?
