I saw i belive it was EA talk about cuting the trailing edge of the brush for a performance gain

Aligning the hood is not a violation. Hood alignment accounts for power.

you can align the hood but you can not alter the screw holes that hold the hoods to the endbell.

Looking at the offset on some of those slots in that MuchMore piece I'd say that you would have to bend the S--T out of the hoods (if you can't open up the holes) to get a proper fit between brush and comm.. Maybe it's not as bad as it looks.

the TMM brush cutter looks almost identical to the KOSE tool. i think the KOSE allows 2 choices of laydown brush configuration & 2 choices of standup config ..

Looking to get more power from my stock 27t epic motor...Right now I am running a TC4 mostly rtr and my car just does not have the power that others cars have on the track...I think it has to be my motor... I have tried a few different brush combos and havent really found something I really like...my latest combo was f brushes with red and purple springs...I race on a large oval carpet track and would like to make my car go faster... I heard a few people talking about rebuiliding a motor to helkp improve performance, I know how to take it apart and clean it, but I am not sure what else could be done to help increase output on it...What would be a good combo of springs and brushes? Thanks Jeff

There is a lot you can do. Maybe this will give you some ideas.

Also as a general rule. Lighter springs add up to more RPM, less torque. good for oval.

Sorry but you are wrong, light springs = more torque and stiffer springs = more rpm. EA and Eddie O will confirm this.

Have you been cutting the comm or just cleaning it and replacing brushes? If not, time to cut the comm.

alright i'm confused. some people say lighter springs generate more rpms and siffer gives more torque while others say the opposite. which is it? can someone please explain why?

I am pretty sure I have read from some of the motor tuners that lighter springs=more torque and stiffer springs=more rpm. Also I read that a lot of people use a green and red spring combo where more torque is better/necessary.

Lighter springs are more torque, stiffer springs more RPM.....
