the vertical slot adds more rpm, but keeping reasonable torque..........

i got glitching problems when i run all my 19t motors without caps.....
so I always solder 3 caps on the motor and not always I use a schottky diode, but sometimes I do....

i use diodes like novak reccomends.....i think the minimum is any schottky diode (35volts 8 amps).......i have 40volts 9 amps diodes.....but there is no difference....these were the closest diodes i found (comparing to 35 volts 8 amps)
the capacitors are 0.1uF..... http://integy.automated-shops.com/cg...l?p_prodid=590

cant cant decide wether or not i was the reedy spec quad mag or the new chameloen 2 for my tc3, they both look like great motors but i want to one with more top end?

c2 is rpmish.....
reedy quadmag is torquish....

I run offroad and i put a v2 endbell on my dynasty... runs horrid. its so much slower than running my regualr configuration, which might be harsh for onroad ( reedy 767s, 175* springs + and -) I'm actually looking to try some new brushes.. ones that can give a little more punch, ive tried basically all spring configs and that gives best overall rpm/torque mix.

Another tuning question ..
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.
Thanks.

It looks to me like you are not getting the full face of the brush on the comm. I think your brush alignment is a bit off.

When aligning brushes you do not aim to have the brush hoods exactly across from each other you aling them so the brush is aligned with the comm.
Check out www.rccars.com for big jim's motor forum you will find everything you want to know there.
I believe Jim's recommendation is a 3/32 deep hole, hole size varies depending on the motor and brush, but you can find that info on rccars as well.
