Hello could someone please give me a discription on what a longer flybar changes in relation to a shorter flybar and vise versa.The good and bad of each with all others items remaining the same.I have myself a little confused on the issue.Thanks for any help.

I have tried many different searches that shed light on lot's but not really on flybar length.Thanks again

I found this info on RCPrecision heli but it is helping to confuse me at the moment.I am assumming that the larger path that the flybar travels creates more stability also creats more stabilty authority(larger gyroscope?).The shorter would be less stable with more pilot input authority (faster)

Quote from RCPrecision heli
I then transition to FFF with 1/2 tank of fuel and there are several things I can do here, If the model noses over, still with the swashplate level, no trim, I can add horizontal fin area, I can move the fin back on the boom (there are limits ), I can lengthen the flybar, or I can thicken the flybar paddles . If it noses up, I can use a smaller fin (or no fin), move it forward on the boom, use a shorter flybar, or use a less draggy paddle. Now realize, all of this interacts so you may end up using a combination of all these.
I am set on the paddles I want to use because of how I want the model to feel in hover, so I vary flybar length and horizontal fin size for FFF trim. If you see my Pro IIK-Ts, you will notice I have a fairly large horizontal fin and a long flybar.
