I just noticed that every duncan raptor owner experience loose thread problems even me experience the same problem. I just wanted to know why this happens?
Its fairly hard to over tighten any decent yoyo. You would really need to put some elbow grease into it. I suspect that most people don’t over tighten but cross thread them. At that point stripping them out would be easy and I could see why people would think they over tightened them.
This advice about over tightening seemed more logical back when you would bust out the axle tower in plastic yoyos. Think fhz.
If you axle is loose you probably cross threaded it.
