hi everyone! sorry, this may have been asked before so dont flame me for asking again. just so much info here to go through.

i have been running the Komodo and Reedy Quad Mag motors recently and have already found a good gearing for each motor.

Question i have is, all things being equal (car, track size/layout, etc), how should i gear a CP 19T? Compared to lets say a KD or Reedy Quad? I have no idea if the CP is a torquey or more rpm-ish compared to the other two.

I know KD is a more RPM motor and at out track i gear it with a final drive of 6.36 (i run rubber tires on asphalt). A reedy quad on the other hand i would gear with a much taller pinon to get a final drive of about 5.80. In my Xray T2 using a 116T spur, thats a 3 tooth difference in pinion size.

Does the CP fall somewhere in between a reedy quad or KD?

Any help on a starting point would be great! Thanks!

Couple of q's, I cut my comm for the first time and am switching to infinity/silver springs. I broke it in for 10 mins, should all the serations be gone on the brushes?
Is it ok to use shims that are wider than the ones it comes with? I lost one and the lhs only has a composite one, but it's wider than stock shim.

Is there any timing difference if the endbell is put on 180 out? I don't think it should change.

What voltage did you break the motor in at? The serrations should be about 75%-85% gone in the break-in ... some people like to even break-in brushes until the serations are completely gone. As for shims, as long as the arm does not bind, meaning it has the correct for-and-aft play, you should be okay - but a proper size shim (washer) is ideal.

With the endbell having a tab and the can having a notch, you can't install it 180 deg out unless you have cut the tab off.

I used 4v because thats what I was told to use, but reading this thread most used 2, I'd say they are about 75% gone.

Run the motor at 2V for another 6-8 min.

Run it at 2v for 4 minutes and then 4 volts for 1.5 minutes.

The gearing for the Reedy Quad is a good starting point. But you may end up using a 1 to 3 tooth larger pinion.

What temperatures are you guys seeing on the CP when you pull it off the track after a race? I was using an FDR = 6.09 and it read a temperature of 195F. What would be the ideal temperature range, and do you gear basically inorder to keep it within that temperature range?

It somewhat depends on the track layout/grip, drive frequency of your ESC, driving style and air temperature. Keeping those things in mind (I'm easy on the throttle using a fairly high frequency on the ESC), for me there are two temp ranges that I shoot for.

Low grip/more than two straights/cool air temp: 165-185F
High grip/a lot of corners/hot air temp: 180-200F

Is it the consensus that the silver springs are the way to go with this motor (onroad, rubber)?

Definitely for TC racing. You may even benefit from adding a small shim on the pos side with the silver spring.

I've never heard about doing this, can you use shims to increase the brush length to run the infinity brushes until they're almost nothing? Or does the spring tension actually increase significantly with a shim?

You can use them for both purposes. Adding the shim to the pos with the silver spring on a new motor will in effect increase the tension significantly.

To keep the tension after 4 to 6 runs, as the brushes wear down, just add the appropriate sized shim to each side.

You can get the shims from here.
