First make sure its centered w/o the paddles.

Then install the paddles and make sure they are the same distance from whatever you're measuring from (i'm not familiar with that rotor head but use whereever the flybar comes out of the head to measure from)

You can weigh the paddles but you'd need something like a 3 beam scale to get close enough to know if they are off.

As a minimum, you'll need a dial caliper to measure each arm of the flybar. Optionally, you could also use a good scale to make sure the paddles are the same weight, but they're not as critical (IMO) as the blades. In short, if both arms of the flybar are the same length (make sure you pick the same measuring points for each I measure from the outer edge of the flybar frame to the point where the paddle attaches to the flybar) you SHOULD be balanced properly.

I was thinking my flybar was the problem with mine. I check and balanced every thing I could with calipers and a blade balancer. I think my problem is this since everything else checked out.

Disconnect the flybar links to the stalizer and disconnect the links to the seesaw. Now the Flybar should be balancing at the slideblock. Be sure the screws are loose enough to let the seesaw balance. Loosen the wheel collars (flybar weights) and slide the flybar one way or the other 'till it balances. Tighten and then spin up the flybar to verify it balances before installing the blades

I've marked mine and it can still slide to one side just barely and cause a vibration.
