Whats the overall sensus on the Trinity xxx brushes, they claim 35-50 runs if you keep the comm trued.--???
Anybody got real-world feedback ? stock , 19t , open mod
Is comm wear reduced that much ?
How do they respond to comm drops ?

I can get 20-30 good runsout of a pair and as far as comm wear they are not hard on the comm at all Just skim the comm when the motor starts to feel a little sluggish.
here is a link for info on the XXX brushes

i still think it is a gimik, I have ran f brush, and 767 over 15-20 times with no noticiable performance lost.

I've found F brushes very brittle (probably only the batch went wrong) but the XXX's we run have been great. Better than great actually, the comm wear is practically non-existant and I'm making at least as much power as anyone else at our track.
The brushes falling off have never been much of a problem for me regardless of compound, its the comm wear that I've seen a huge improvement in.

The only gimmick is the price.. and the fact there the first brush they actually tell you not to change every few runs.. I can not remember the last time i got less then 10-20 runs out of a pair of brushes..any brushes will last if you dont cook them..

If you run mod they really do work.. you should be able to get 50+ runs in stock motors out of them.. Heck i know a few guys still running the original Orion brushes from 2 years ago.. they easily have 50-100 runs on them and there still smokin fast..

What drops are working good with these brushes?

I would recomend zubak.. they seem to be the best all around drop..ive seen most of the guys using his drops o these brushes

I have found these brushes to work great. It took me some time to get use to the break in time. I find that these brushes take a good 600 to 700 seconds to break in at 2 volts. All i do is slightly cut the come ever three to four runs to make sure its not out of round. The best brushes I have used!!

I just recently started using them and they have worked great, u gotta break'em in for ever lol........ but they are worth it imo. A buddy of mine used them on his ultra-bird here in florida in the FOCAR series and ran the same motor with the xxx's from march until november ....... thats racing once a month all practices, qualifers and mains ........ not bad for about $15 upfront;)

Im the same way.. I run putnam brushes god knows how many runs... I just reserrate when cutting the com and rebreak in. Ive run the XXX brush... However I found to go fast I really had to get creative with drilling etc etc to get them fast and to get them to break in quickly... Ive still run faster on my Xbrush putnams

In stock I run putnams, and will normally change brushes each week. I'll take them out and re-serrate them, and give them to one of our novice drivers. He knows they are used, but there is still a lot of life in them, and it helps him save a little money so I'm all for it. I tried the XXX's in stock, and just couldn't get them to run like my putnams. In 19 turn and modified what I have been doing is using the XXX brushes in practice, and then running Putnam X's in the heats and mains. It lets me focus on getting the car set-up and is one less thing I have to worry about while I am practicing. I still think the X's create more power though, that's why I use them in the heats and mains.

The xxx stand-up brush seems to be very high on the rpm side.As compared to the x-brush for example,i have found that the xxx brush seems to produce more rpm, less torque,and slightly less overall power than the x-brush.The high rpm's seem to equate into higher amp draw numbers also.
The brush does seem to take a few runs to get up to its peak condition (about 2 runs) but seems to hold the same amp draw and dyno numbers for more runs than any other brush without having to reserate brush faces or any other "work".
overall i think it is a very good stand-up brush.every fresh set you try seem to produce the exact same results...no difference from batch to batch or brush to brush.

Thanks for the feedback , some places are selling these -5 prs for $40.00 which seems like a pretty good deal.
I'll order some tonight :thumbsup:

They make decent power and RPM but the brush is way to soft for my liking. When using heavy springs in a stock motor, after 5-6 runs the brushes are too short to use anymore. The way I see it, a new stock arm is less than 20 bucks and I can get at least 30 runs on it. At 10 bucks a pair the XXX brush doesnt seem cost effective. Cheaper to buy a new arm or motor than to keep buying these high -priced brushed that offer no better performance than the 4 buck a pair brushes.

These brushes were intended for use in touring cars where comm wear and heat are the biggest concern.

Mayhem nailed it...These were never intended nor developed as a "high performance" brush, but rather a "high endurance" brush. They work very well for their intended application, but haven't even dethroned Trinity's 4499 E brush performance-wise, much less the higher performance compounds offered by that company that colors their shunt wires...:thumbsup:

I have a set in one of my 19 turn motors that probably have 50 runs on them. I haven't really had any problems with them lacking power on the track. As for them wearing fast, not sure what that's about.. I think I'm probably running harder springs on my 19 turns then anyone is on a stock motor, and I don't see the brush getting too short.

Hell, I went to maximus all summer long and ran the same set in the same motor, and it was fast enough to tq and win 3 races in a row, so they can't be too bad. Oh, and that set, I got from Paul Chagnot, out of a mod motor that he ran all weekend at the winterblast that previous January. The brushes are still in the motor, and I'm about ready to stick a new arm in the can... brushes are staying until I see a performance decrease.

I'm not saying they are the fastest thing out there, I have gone as fast with other brushes as I have with these, 4383's, putnam x, as well as a reedy brush, I just find that the consistancey allows for fine tuning gear and other factors much easier, and it also makes getting the car good alot easier too, as I know exactly what the motor is gonna do every run, and I probably spend about 1/2 the time working on motors when using these because of the repeatablity with little to no maintenance. I have actually run 3 races in a row 19 turn, with no motor dissassembly, not even removing it from the car and had good results, 2nd run was actually faster then the first, and the 3rd went back to where the first was.

To each his own.. but figure it out, 50 runs divided by 15, that's 3.33 cents per run.. a hell of alot better then the few runs you'll get out of a 3.50 pair.

I tried xxx brushes a couple weeks ago in the mod car. IMO they were the flattest brush I have ever tried. Putnams X brush was 1 lap faster. :thumbsup:

I guess the lower the turn more or the higher the temp of any motor these seem to hold up better.
If you run a 767 at 170-180 degree's ' like alot of racers do at our track , your not going to get many runs out of them.

Where these can basically take all the heat the motor can stand

i love them we burned a motor to the ground and then reused the brushes in another motor and won the a with it. if you run in the heat it is the only brush to use.

Exactly.... I rana summer series.. and used a single set all summer long, 19 turn oval. They were as fast as anythign else I tried, had great repeatability, and absolutely no maintenance needed.

I'm gonna stick them in a 6 turn next week, see how that works out. My guess, they will be fine.
