Default Best Brushes for 19 turn?

I am curious what the best brushes for 19 turn motors are. Namely the trinity 19 turn motors.

Some very fast guys are running the 767 brushes. I see on the reedy web site that 767 brushes are best only for offroad truck, and for touring cars the best are the 764,766(actron) and 769.

Has anybody tried these other brushes? Results?

In some ways you should be more specific...

Trinity has a ARCORNITE 19 turn motor with stand up brushes.

Trinity also has a D5 motor that can have a 19 turn arm in it, these have P-94 brush hoods... and are almost square...

But it appears as if your talking about a Chameleon 1 and/or Chameleon 2 motor, since the brushs you refferance are laydown style...


Have you ever tried Trinity 4500 brushes? I've had some interesting results with them on ohter 19 turn motors... They are very hard... the serrations will last a long time...

Any good brush can be made to work well I think.

Specifically Chameleon/2.
Laydown brushes.
Hightraction Carpet.
about 45-45 degrees.
TC3
GP3300

Need anything more specific?

PS: I am more concerned with power over longevity.

I've had good luck with Putnam brushes... a Green shunt on the positive side and Blue shunt on the negitive... A few drops of Zubak's speed juice...

I also like the Trinity 99+ brushes... I don't perticularly like the cross cut style however.

I honestly think you can make any brush work well... They all seem to like just a bit differnt spring, or something... but if you take the time, you can get most any of them to work well...

You don't nessasarly have to give up longevity to get good power... Try some of the 4500s some time... They last long, but they also make good power, or at least they are capable of it...

My driver placed 2nd in 19 turn this past weekend in the NW point series. We were using a trinity 19t with green on the positive and blue on the negative with purple springs on both sides, with the negative tweaked just a TAD softer.

I also built one that was pretty fast with the 767 on the + and a 766 on the -, using a purple spring on the + and a red spring on th negative tweaked JUST A TAD firmer.

All motors were using tribo comm drops.

And by the way, the 769 brush is just a 767 with a hole in it.......

Later Eddie

Don't forget the harder the brush, the more wear on the comm. Also applies with spring tension.

For the Trinity Chameleon 19 turn try the Trinity 4503 /4 with Trinity Red Springs.

Gearing - use a final ratio of around 5.0 for small tracks & 5.3 for large tracks.

Are you sure about this info?

I am running 6.33 overall in my XXXS G+ with a Chameleon 2 on a smaller track. Occassionally I will run 6.58 in it when traction is good.

I think on your comments you meant 5.0 on large and 5.3 on smaller correct?

Oh and I use Reedy 767 or TRINITY 4499 with good results.

Yes, mostly what I am hearing is that the 767 (or putnams) are the brush to use. I was just a bit confused about the brush applicationi chart on Reedy's web site.

FDR of 6? wow, almost at 8 for this fairly small tight track.

Default Brushes for 19t

I have great results with 767's in the reedy spec Quad mag motor (ASC#514)
I run on a loose oval and it pulls smooth!! I cut the comm and use new 767's every other week.

Trinity 4499 or 4504, both have the same compound. The 4504 is crosscut.

Interestingly enough, DynoMoHum, the D5 19t does NOT have the P-94 brush hoods, it has the standard stand ups. The P-94 brushes are not ARCOR legal, therefore the EPIC "outlaw" 19t is the only 19t with the P-94 "big" brushes.

It doesn't matter anyway, the chameleon is by far the best motor for touring, and most all other applications. (in my opinion, at least). I have been trying many other 19t motors lately, and nothing else matches up.

Proficar- you must be doing something wrong then because the C/C2 are 80-90 watt motors and the good ARCOR 19s will make 105-115 watts which is a ton faster.

Nitrojonnyd - You are correct - I mixed them ratios up!

The trinity brush 4503/4 gives better comm wear and find that it revs more than reedy 766/7 brushes.

if you like the 767 brush...

try out some Team Hurricane "Golds"...they work awesome and give more power then the 767 without any increased comm wear.

here's their site: http://www.teamhurricane.net

My comment about the D5 motor having P-94 hoods is simply that the D5 comes with P-94 hoods... You can put any type of wind you want in a D5, and unless someone changes the hoods, they will have the P-94 on them.

ARCOR D5 motor builders change the P-94 hoods and put stand up hoods on them... that is true...

ROAR is curently trying to re-write the 19 turn rules, perticularly for oval racing... it seems that ROAR may end up with differnt 19 turn rules for Oval then it does for other classes... but that all remains to be seen.

My personal opion is that it's not even really clear that it's legal to change the brush hoods on a D5 to a stand up brush... at least for ROAR racing. There is a ROAR rule that states you can not change the 'orientation' of a brush... If oreintation refers to standup, laydown, or big/small... it may very well violate ROARs current rules to change from a P-94 to other
type of brush.

ANYWAY... There is currently a variety of bushes used in '19 turn motors'... To be safe, one should make it clear which type they are askng about...

My experiance with the 4500 brush, is that very good comm wear with them, no worse then with any other brush, and since the serrations last longer, I get better proformance with them, over longer periods of time.
