Hopefully this won't sound like, (or turn into) an info-mercial... :thumbsup: There are many god brushes on the market, but here's what we use:jmracing said:looking for advice on brushes and springs for the CO27 motors.monsters were easy these seem pickier.and whats a decent amp draw with these at 2V with a fan.
Start with the setup described in the above post. If you need more bottom end in the infield, start by putting a purple spring on the positive while leaving the red spring on the negative. If you still need more bottom end, put a purple spring on the negative as well. This will also eliminate the brushes from glazing and the motor from running flat late in the run if that scenario ever happens to you.Stratus54 said:Tod... I also run touring car... what brush/spring works best for TC
You can measure the total width of the face of the brush with a pair of calipers. If you don't own calipers, you really should pick up a pair. You can get some really inexpensive digital calipers that are great for R/C thru Harbor Freight. These are a must have tool in R/C, to measure shock lengths, tire sizes, frame heights, brush and comm sizes sizes, etc;tightline31408 said:hey guys! how can you tell or how well I know how much I trimmed off. is there a gauge or a file i can get. any help would be appreciated.
