I got my Reedy Quad Mag pretty well dialed in, other than my driving the car has just as much motor as everyone else at the track. But I've run into a couple of questions that I can't find the answers for.
I read you should drill a hole into one, or both brushes, (using 767's) and I did this but I wasn't sure how far your supposed to drill .. and I cannot find the site in which it was posted. Do you just drill a little ways, all the way through, or does it matter? I drilled about half way through the brush .. can't say I noticed any change in speed however. What's the theory behind this? Is it just one pole you drill into?
Also I've got my brush hood aligned well, but it appears the brushes are still cocking inside the hood .. this is indended, right? Here is a pic of what my brushes look like after several runs.
The red box is highlighting the dark area on the side of the brush the appears to not have good contact with the comm. Is this okay? I don't really see anything wrong with it since the motor seems to run fast and strong, but thought I'd ask anyway.
