1520-1650kv problems

Hi

Anyone know what this brown is? Should I just remove this?

Castle 1520-1650kv motor.

Guessing that’s how they balance the shaft. But I could be wrong.

My guess too. I’ve only seen it blue before though.

Don't mess with it

I'm with you. My 1717 1650kv has some too.

Unless it's broken, why mess with it? I say leave it unless you're trying to fix an issue.
