Need Blade Doctors - What's this noise?

[sashheli]

Rebuilt the head after a small crash... Nothing major... Replaced feathering shaft and main shaft. After that i replaced the motor, and the problems began: Getting this strange whooshing noise righ after spool up, once the noise begins the heli circles counterclockwise.

Is something wrong with the head? My head? Please help.

Couldn't hear it too well, but looks like the tails not holding it, which could mean the blades are spinning the wrong direction or pitching incorrectly.
Check and see if the tail blades are going the right way. Might have a twist in the belt.
Not sure if this helps, but give it a try.

Looks like tail is not set up correctly. Are you using heading hold on the gyro?

well, it was the head issue. broken flybar seesaw holder... i noticed it being too loose, but due to inexperience did not tear it apart to double check. Thanks everyone for other ideas.
