A properly balanced flybar will look like this. Hold the 2 blade holders with their balls down and rest 
your thumb on the center hub to point it vertical. Flip a paddle down and let it seesaw back & forth. It 
should land level or near it. If you set it to level and one side falls down all the way, this guarantees the 
“shakes” and an unflyable machine. We need this flybar to balance as in the photo.

The “L” control arms are held by a setscrew, probably stripped like mine and void of Loctite! To get it 
out, try SAE sized wrench, like a 1/16”. These can NOT have slippage,must be LOCKED/Loctited to the 
shaft. 

(Addendum: 

”L” is still movable on shaft even after Loctite!) You will have to work with BOTH “L” 

arms to get a level balance...
