could anyone help >>>>>

can anyone give any idea on which brushes to use and when

which help with more torque which help rev more, or hot day cold day

its really a mine field i like the putnam brushes the seem to work well in my 27t and my 19t but is there anything better i have tried the actron brushes by schumacher but dont seem to rev as much as the putnam dyno'd my 19t std end bell element with putnams and read 36650rpm and that was without modding the brushes...

You can try the following:

4499 - Trinity - all around brush
767 - Associated - all around brush
F - Finish Line - work best on stock motors, especially the CO27
XXX - Trinity - use on hot days outside, also works good for 1:12

These are most common used laydown brushes. For more torque, try harder springs - more RPM, softer springs.

You are using the best brush already the putnam, i tried all the others and went back to the green and blue, there is no other brush that work better for stock/19t class hands down.

I've tried 4303, 4304, 4305, 4499, 767, 766, XXX, and the F-brushes and I like the F's the most. I always know I'm gonna have a good motor if I just throw those in. I run the Trinity and Reedy brushes a lot in offroad, though. I've heard a lot of good things about the Putnam's but have never tried them. You can get the F's for $2/pair here.

I do not mean to argue, and I know this goes complete against what most say, but from one of the master's EddieO, softer springs give you more torque and harder springs, give you more RPM. This is why in a PK2pro motor, which has torque, you run purple springs to get the RPMs in balance.

See: http://www.rctech.net/forum/showthre...eo#post1959849

and look for a the posting by EddieO.

I'm not trying to pick a fight here, just letting you know.

767 brushes or F brushes they are great all around brushes. Play with the spring tension, I like to run purple 7 on the postive side, and 6.5 on the negitive side, but this is for a small tech. track. On a flowing larger track, I will run red on the pos to green on the neg or purple on the pos side and red on the neg side. Warning with the CO27, you must find the sweet spot with the gear. I have seen this motor run hot if over or under geared. I also have seen 4 teeth difference from on Co27 to another Co27 motor... But when you hit the spot you will not want to run another motor. ;-) I know you did not ask about the Co27, but this gives you an idea of what to play with. You have already have one the best brushes on the market...

I agree with bvoltz ,I thought it was the other-way around for along time but a guy that has put a few motors together for me gave me the scoop on what springs do what. I run TC and the motors he's built for me using red/red or red/green have had more punch out of the hole than when I had purples on both sides...
