thanks for your tips

i'm using the fantom 315 brushes and have blue springs. maybe i should try red springs and maybe gear down if possible.

btw, i have lathe the motor and already break-in the brushes.

anyone know what are those green compound that they used to coat the armatures so that they will not short. are those epoxy? i only know they use epoxy to balance the armature! any hints?

Which putnam brush's do you recommend for a stock motor? The green shunt or blue shunt brushes? Also, what type of extra maintenance do they require? Just more frequent cuts of the comm or something more?

Thanks,
Rob

Rob, I and I am pretty sure Todd Putnam would recommend a green on the positive and a blue on the negative. You are correct as I was talking about more frequent cleaning and possibly cutting of the com.

Hi Guys,
In my Atlas (Matrix) I cut the brushes down just like big Jim says, but I'm wondering how you guys do it. The brush always crubbles on the edges. Is there a way to avoid this?

And will it benifit the 23T motors?

I use quite a fine file, it's not very big and I don't put a lot of pressure on it. Are you using the #766 brush?

Default heat sinks

I have clip on heat sink that came with my xxx-s when I bought it. If I use this heatsink with my stock motors it covers the holes in the motor can on one side. I was wondering if this is actually hurting the motor by not allowing proper airflow through it with the holes blocked up? There's no way to use the heatsink without covering up the holes on one side. I also read that the holes are there for more than just cooling. Could the heatsink also be hurting the performance on the motor by disrupting the magnetic field?

Thanks,
Rob

Default heatsinks

rob,

i was wondering the same thing. i run both the tc-3 and xxx-s, and had heatsinks on both. while i was at the carpet nats last week, i was trying to lighten up my xxx-s. to make a long story short, i took off the heatsink, and saved a good chunk of weight. after running, i'd tech my motor w/ my heat gun, and it was still at around 140 degrees fahrenheit. as i toured through the pits, i noticed alot if not most didn't run heatsinks. one of associated's drivers once told me that once the heatsink heats up, it really has no place to dissipate the heat, so it ends up heating the motor. another thing, the lighter the color of the heatsink, the less heat it will dissipate. anyway, that's my opinion, other's might disagree, but try what works best for you.

Default Brushes

Hello all--

It has been 5 to 8 years since I did any serious racing, and I have some brushes that have been sitting around for that long. I'm wondering, can brushes go bad after a while. It may sound like a stupid question, but no question is stupid if you donít know the answer.


Thanx for any input you send my way

Rich

I think the newer compounds of brush would be better than what was available previously.

I agree, I think the newest brush compounds are the best bet for outright power, but I do know of a few guys who've had to use some old brushes that were laying around(especially when we had a brush shortage some time ago), & they seemed to work fine. Do you know exactly which brushes you have(the old ones, that is)?

Maski, there is no stock motor with cobalt magnets, Reedy's upcoming new stocker is codenamed Cobalt, but it will NOT have cobalt magnets(they're illegal & cost WAY too much). It's just the motor's name for now, & there's noo guarantee it'll still be called that even when it's released.......
