This has been asked and consequently ignored several times here...Where can on find replacement brushes for the Stockstar?! Love the motor, but right now, if I can't get brushes, it is soon to be a rather expensive magnet to collect my extra screws, etc!!

All AE/Reedy distributors stock the brushes and springs. This means that any hobby shop that currently sells AE or Reedy can order them for you if they do not already have them in stock.

Lemme open one up first and I'll tell ya 
I mean, it looks like you just unscrew the hex that the shunt's coming out of, but I'd think thats going to make the brush try to drill itself into the commutator, which is no good. I'm not gonna pop the top until I'm sure I know how these things are made and how to properly take one apart.

easy to take apart, man. The screws that hold the endbell are the obvious easy part. The brushes come out by, as you said, unscrewing the nut where the shunt is coming through. You cant over-tighten it tho cuz the way its threaded and how the hex part sticks out over the endbell forces it to stop as you tighten. I took mine apart already, easier than a regular motor to take apart and you dont lose springs either. I had to use needle nose pliers to loosen the brush-nut thing, but a small crescent wrench could work too.

Rick do you think there is really much power loss by screwing on the brushes instead of soldering?

Well OK, but what keeps the faces of the brushes from twisting into the comm? I'd think you'd have to hold the springs back as you unscrew the brush "barrels", otherwise you'd seriously start garfing up either the comm or the brush. It'd be like putting a standup brush in a laydown hood and turning the motor over

keyed i beleive is a more accurate term. The brush doesnt sit free in the endbell per se....it can move in and out (as it should) but cannot twist.

I got my first stock star motor in early last week, I trued the comm and used my slave motor to break it in for about 5 minutes at 3 volts. I raced it on a concrete oval friday night and I have to say, I wasnt impressed at all. I ran 2 or 3 5 minute practice sessions and 2 heats with it, however I switched it out for the main becuse it just wouldnt keep up with everyone else. After switching to my team brood peeler co27 with the same gearing, i was right on par with everyone else speed wise. Motor temp wise, the stock star was running 135* and the co27 ran 110*. I will have to get some springs to play around with, but my first time out with it, I am not that impressed.
