Hi,
I wish to reduce te current consumption of my T2 motor for races on carpet.
I'decided to use silver brushes instead of copper brushes. I used a Muchmore to make my tests. I found 1,2 A with silver brushes and 0,9A (under 4,8V) with copper brushes. I expected to find the opposite results. Do you have an explanation ?

What should I do ? Use copper brush on the negative pole and silver on the positive one is it a solution ?

Best regards

The increased amp draw came about because the silver brushes are more conductive than the copper brushes. You should get a little more power with the silvers :)

Hi,
Out of factory "classic" T2 (not sure for new "round") have copper brush on positive pole and silver on negative one.
