Strange Noise from SE116

[hzz]

Newly installed Se116, with about 5 hours on it.
I have been breaking it in as suggested.

It has had a strange noise right from the start that I thought might go away but so far it hasn't.

It happens at 2500-2600RPM, and it sounds like "wooooooooo", fairly loud.

Only at those RPM's, never at any other time, and performance is fine.

Any ideas?

It could be the gears are still seating and the noise will diminish as you complete the break in. I would also check your gimbal bearing to make sure that it is good.
