I could try that if I knew how to get the blades off.
I tried meddling with it today and now the blades start turning then stopped after half a second and jam and the motor still makes a noise. Crap. But then I gently bent the blade center and it started turning again. But still makes the noise and vibrates like crazy. I'd say the blades are really unbalanced.
Attached is a video of when it wasn't turning. I don't feel safe running it longer than a minute. It sounds like it's struggling and will eventually slow down.
