Hi.

I'm the guy, who fried an armature, remember?
I got a new armature and drove last weekend with it, total
4 batteries. With the last two it started to feel less-powered,
as the brushes had worn out their serrated-faceness. I cut
a half millimeter groove at the middle of the brush (just to
see how it reacts) and drove it again this weekend. The motor
was hot as hell while driving in inside, twisty track, gear ratio
7.86, free drivedrain and a heatsink installed.

What am i missing here? I'm going to change the brushes to
Reedy serrated (or drilled, what first comes to hand), but
the gear ratios are lower that other people use, and my car is
working good.

Oh, about the car's handling; it had quite nice accelleration (have
had better though), but seemed to miss some top speed ->
not-serrated brushes..

Oh, well, just wanting to race stock. The 11 turn handwound
is a bit .. well .. profitable to my LHS.. :-)
