What’s causing this issue? (Reverse sometimes works and sometimes doesn’t)

here’s a video I made that shows it.

Brushes are probably worn out or the comm is dirty ,try electric motor spray cleaner or
take it apart an clean by by hand ,you can use some very fine sand paper to clean the
COMM where the brushes ride on ,in time they get glazed up!
It was a common practice to do that back in the day in racing brushed motors!..

This motor isn’t designed to be taken apart, but I’ll find a way that’s not destructive. Thanks!

I was thinking the same ,some you can find the rebuildable ones on ebay pretty cheap ,stock

There actually is a special "stone" for cleaning commutators, rings, etc. Can not remember the name, but it is white. I used them regularly to maintain generators a few decades ago.

I also have worse range on my TX/RX after upgrading to 2.4ghz, the antenna isn’t cut, what could be causing it? I removed the capacitor from the motor since it popped, is that an issue?

The motor cap is there to absorb a lot of the RF noise generated by the arcing brushes inside the motor. It shouldnt be causing an issue with the kit not wanting to go in reverse but could be a reason your range is taking a hit.

Thanks! I already have replacement caps, I just need to install them.

I’m a newbie, but was having this trouble also. I recalibrated the ESC per the instruction manual, and it fixed it.

Everything comes apart If the motor has a housing with the lip mashed in to hold the endbell on, you can pry those out to remove the bell. But it can be a pain. A lot of the old slot car motors were supposedly not serviceable, but we did anyway.
