Joe, it is suppose to improve torque with a slight loss of rpm.

I think you have that the wrong way rcnitro, a cut brush will improve rpm and decrease torque.

Sosidge,
Not when cut this way.
Lose rpm, gain torque and cooler temps.

I've benn running my mvp with the cut brushes (767 on + and 766 on -). The two hardest things to figure out with this motor are the hood alignment and proper gearing. I find that 26/72 (6.92) on my tc3 seems to work best for my usual track (ripon speedway). Car has nice bottom end and tons of staight away speed. It's a thing of beauty!--AL

At least you can get the #767's, I'm still waiting for the LHS to have their order arrive.
I could have got them in a while back(and some Putnams too) but thought I'd wait and give them a chance.
My Mistake.

Simon, one thing myself and a couple of others have found only with Reedy motors (I have used a TI 8x2 and a MVP)is that you seem to get a lot of wear marks (almost like serrations) on the com and brushes. One way I fixed this problem was changing to Peak brushes with the 8x2. Have you come across the same thing? It is very odd as the Reedy brushes don't change colour when this happens, so I am assuming that it can't be from overheating.

Hey Mike,
I never got to run my Peak 8x2(sold it)so I've never come across anything like that.
When I ran mod, I only used the Peak brushes, through them being easy to get.
I've learnt a lot in the past year or so about what to use and what works, Until I race mod again(next year) I can't put some of it into practice.

I only use trinity "E" brush with red and green for spings, also I found that Big Jim has some of the best tuning tips. He had talked about puting a motor in the ice chest or something that is really cold with ice and put the motor in there and leave it there till it is really cold the more the better, I put it in a small bag to keep water out. This boosted my motor really fast and the motor does not get very hot during my run.
Try this with a old motor if you want to test it out and watch the amps jump

Have a nice day,
Drew Roberts
