Default Aligning brush hoods?

I see people telling everybody to align their brush hoods to get good power for their motors. No one has ever actually explained how to do this. How do I do it? I would be doing it on my Chrome Stock RS and P2k Pro.

Get a brush hood alignment tool. You need a bar type, not one of the fancy ones. Put new brushes in the motor and run it for 30 seconds or so at 2.5 - 3 volts. Remove the brushes and check the see if the brush wear is even. I like to use serated brushes because you can look at the serations and it is much easier to tell if wear is even.

If the brush has worn evenly, leave it. If not, slide the tool in to the hood and twist the hood in the appropraite direction slightly. Replace the brush and run again. Kepp trying until you get even brush wear. Then do it with the other side.

Make sure the test brush, if you use one, is the same size as the one that you use to build your motor. Each manufacturer's brush is a different size, i.e. Trinity, Reedy.

Niftech makes one(#3032), but their price seems kind of steep to me at $25. Check out http://www.niftech.com/catalog/index...ode=3000series

There's another company that makes one that's mounted on the outside of the hood to achieve proper alignment. Unfortunately, I don't remember the company name (Parma or maybe Racetech, believe it or not, I even have one)???

IMO, the Parma/PSE one works the best for $12.99 at: http://www2.towerhobbies.com/cgi-bin...1&I=LXDB93&P=7 .

Yeah, you want one like the parma one. This is all courtesy of Big Jim by the way.

I hate to be the voice of dissent, but the Parma unit will align the brush hoods but the brushes themselves will not be aligned. It works to a point.

What follows applies mainly to 27t stock motors...

The problem is that the brush moves very slightly in the brush hood when the armature turns, slightly cocking the brush. Each hood has to be aligned independantly, using the method Speedo mentioned.

The racetech bar is the tool I see recommended elsewhere for the job.

Oh yes, Simon is right. I was thinking the parma one was a different type. You just need a bar.

I posted this on Team RCV Forum but here I am spreading the word.

Racers Edge makes one of these tools


According to Corse-R, Stormer Hobbies sells them although they are not listed on their site.
Just ask them for the PN. I just did

Hope it helps
