Brush Springs
 

I have always been told that brush springs get firmer as you go from purple to silver to black.

I have some of all three and the purple springs feel the strongest. Today I was told that spring colors don't make much difference anymore and that its best to make your springs stronger by bending them.

Any thoughts?

thanks

If they are all trinity springs, that is correct.

Blue Super Light
Green Light
Red Medium
Purple Heavy
Silver Extra Heavy
Black XX Heavy

Now, there is an older trinity black spring out there that is black, but they are polarized (for positive side only)......

Where it gets weird, Reedy, Orion, etc all made springs in various colors, with black and silver being very commonly used, even in multiple different spring rates.

There is no way a legit trinity purple is heavier than a real trinity black or silver.......they are both like coat hanger wire.

In the end, the best way to do it is a spring gauge and bend them....you can only make certain springs so stiff though....

Was gonna mention the Fiddle Stick or the Trinity make of it. They are the most consistent. I got one of the Integy spring dynos......not good enough to use on springs, to light for a boat anchor.

Thanks...

The strongest ones I have are the purple that are on your motors. Can you reccommend a source for the real deal silver springs that are actually harder than the purples?

Thanks"thumbsup"

Strange, my integy unit always worked fine.....just was a pain to carry to racers with everything else and you could not measure on the motor....

We used to measure our race springs before big races with it, to make sure they were within spec....the trinity blue-purple weren't super consistent in quality control. I had reds that measure as purples or greens.......greens that were blues, etc....

I never liked the trinity spring thing....the fiddlestick was and is still the best, the slot car guys still use them.

You probably got an OG version.:ror: I've had this one maybe two months. I'll run over to RcGroups an get a definitive answer.

I have real trinity silvers and blacks...pretty sure they are on the website.
