I couln't imagine such a piece could break

[LeviMan2001]

just like any of the internals grenadeing at that rpm.

@johannes914 It's a "cheap" aluminum casting.....never meant to spin that fast.....much like props 911 fans are!

@johannes914

I could not image such a piece to stay long without braking up.. Aluminum, thin..

[batvette]

@MikkoMuhis I don't think it's the thin part as much as aluminum, especially cast aluminum, is not the best material in applications where heat and vibration are going to be common.

@batvette

Yeah, that sounds smart. Someone before me told that would be cheap casting aluminium.. o.O
