MMM 2200KV sounding like a Electric Drill ??

[sabongi]

Just got my MMM, took it out of the box, installed EC5 plugs and ran it.
Motor is making a electric drill sound, something like a really bad bearing or something.

What can i do?

I'm in Brazil, so it would take 1 month to send it back, and probably 2 months to receive it back from you.

Can't afford waiting all this time. Is there something i can do?
Bearing oil maybe?
