Cool Gear Ranges

I ordered an Epic Roar Stock and an Epic Chameleon2 for my TC3. I am running a 72 spur. I race on Medium to large asphalt tracks in California. Can you recommend spur gear ranges that would be the most efficient and effective, while keeping the heat to an acceptable level. Also what are the acceptable heat levels on these motors based on 5 minute races.

Yes, the positive brush does wear a little faster, but its not a huge difference. Generally after 2-3 races both brushes are flat faced anyways.

Occasioanlly we do use this in modified racing, but it isnt as crucial. In modified you generally spring much stiffer to prevent the brushes from bouncing. In most cases, we run a stiff purple spring on both sides.

Are you running rubber tires or foam?

if you feel like switching out your spur, you can gear: 96 spur with a 38 pinion, or right in that range, up or down a tooth. thats with a stock motor, i dont know about 19t

ok, if you are running the 72 spur, with a stock motor, you should gear

72/28

with the 19 turn, you should gear 72/26


this is according to associateds website. these are ballpark numbers, your motors might run better being geared up or down one tooth. hope this helps

Default BLACK MAGIC & TRIBO

Brandon,

I've heard that your "black magic" brushes have Tribo baked into them. If this is true, should I not be using the Tribo drops along with these brushes? Could that much Tribo actually hurt my motors performance? Too much of a good thing?

Brandon,

One more question. Will I harm the chemical make-up of the black magics if I spray out my motor without removing the brushes? I don't like to unseat them unless i'm cutting the comm.

Fuzzy,

At the stock nats, I tried baking the brushes I had there in some Dextron III mixed with some other oils. It was nothing more than messing around... thats how you find out what works and what doesn't. A lot of people thought it was Tribo because it was red, however thats just rumor. If you bake Tribo, it becomes really goey and doesnt work very well at all. So to answer the question, no, there is no Tribo in the brushes. There is however 1 of the same ingredients in a concentrated form that was molded into the brush during manufacturing, however that is my little secret. I cant reveal everything we do on our new products

Depends on the motor spray... I have never had trouble with Fantom, Performance Plus 3, Trinity, or Orion motor spray. None of those seem to harm the brushes. I have ruined some brushes with the Duratrax stuff and the dynamite stuff though, however from what I have heard the forumla was improved on both of these sprays a few years back and they are safe now. I guess I just found what works and go with it My personal preference is the Performance Plus 3 because it has the most air pressure and seems to clean the best because of it. The Fantom stuff is nice though because it doesn't smell as bad as the other sprays.
