As I said, imbalanced flywheels are a common problem. Unfortunately, fixing them is an even bigger problem. It's definitely doable, but you'll need to do a full flywheel cage disassembly. If you're not an intermediate modder, this may not be a good project.

But if you are, then the solution is quite simple - just a little bit of electrical/masking tape on the light side of the flywheel does the trick. Check out thread.

Look, if it's not affecting performance, or you're not a confident modder, my advice is just deal with it. But if you're adventurous, OCD, or a Nerf addict like me, this is a great modding opportunity. And while you've got it open, may I suggest a new cage, some upgraded flywheels, and a couple motors 😉
