Post-race teardown and cleanup of one of my flexi race cars.
During the race, power seemed intermittent at times, and car was slow overall.
Brush/comm inspection - looks fine, plenty of brush life left, comm looks fine.
I found the problem - broken front axle oilite
Motor is fine. Car is broke Easy fix.
The funny part is, I had a pre-conceived notion the motor was failing.
And I totally admit that was stupid of me
