We have a forum in the racing section of Rc Tech. Go to that and look for "Horsham Rc Racing 2006-2006" or something along the line of that.

By the way, Epic CO27 is what most "fast" guys run.

Default prep

Besides which stock motor to run...what about regular maintenance of the stock motors we already own. Here's what I do....anything else I might add to help?

Visually inspect commutator thru a brush hood. If the comm looks like it's worn I do this:

pull motor apart, take armature out, take off washers/shims
spray endbell and can with motor spray
cut comm
use xacto in grooves
spray armature/comm with motor spray
lubricate openings in bushings
loosen brush hoods
use Trinity's brush hood alignment tool, then tighten hoods back down
replace worn brushes with new ones
put motor back together
run motor for about 3 minutes at 3volts
place motor back into vehicle

anything I might add or take away from this routine?

I use a ball point pen on the grooves just before the xacto knife. It helps round the corners a bit to prevent brushes from chipping every third of a turn of comm. Then a toothbrush between xacto knife process and spraying clean the debrise. Hope it helps.

I do not suggest running a ballpoint pen down the comm slots after cutting a comm. This will deform the edges of the comm plates, reducing the surface area that the brushes have to contact. This results in a reduced charge of each segement.

I agree: Do NOT run a ball point pen down the comm slots!

doing this rolls the edges down, making the effective slot width greater, and is a bad performance move...

I understand that the slot edges can be a potential source of chipped brush edges, but there is a better way:

Something I learned from Big Jim: After you are done cutting the comm, CAREFULLY use an xacto knife to clean debris out of the slots, then -- use a soft pink eraser (Pink Pearl / Ruby) to LIGHTLY "buff" the comm surface to polish the slot edges. The side bonus is that the buffed comm seems to reseat the brushes a bit quicker...

Ball point pen is so `last` year

knife blade (don`t cut your self or slip) or
use a piece of cut Header card from your parts bit`s ,just strong enough to clean out groove but if you slip it doesn`t damage the comm or your fingers

cut the header card up into loads a little squares once you used all 4 corners throw away get some more
yokomo headers are very good
cheap way of doing it (what a tight wad)

On the topic of hood alignment, I do not care if the hood is aligned straight across, I'm more concerned about the hood allowing all 4 corners of the brush to touch the comm. I align my hoods to do this. Yes I use an alignment tool to move the hood in order to achieve an even wear pattern for the 4 corners.

So let the chips fall. I guess chipped or broken brushes must be better than decreasing contact patch by .005 of an inch. Most guys that I know still use pens.

I have used a ball point pen for years, and no problems. I agree with stratus racer

For stock and 19T, using a ball point pen decreases effective timing for each segment of commutator to the leading edge of each brush. Its just like knocking off both edges of the brushes... you lose performance. YES the ballpoint pen trick is great for longevity, but for performance, it is a definite NO.
