How will a longer flybar affect the flying characteristics of a Fury extreme? The flybar I wish o try is the Freya long flybar which is 4 inches long than the current fury flybar. I have mixed opinions locally.

It will make the Fury more sensitive in the center of the stick, you might want to ad Expo. Loop & roll not much difference. Not as crisp on tight manuevers.

longer flybar will not make it more sensitive around center stick, just the opposite.

I am well aware of that and I believe he left behind some valuable reading material including this matter which proved my theory. I have it in my collection.

Here is something else I found..

w3mh.co.uk or read this from Collin Mill:

The speed of response of the flybar to commands can be adjusted as follows:

Increasing the weight of the paddles slows it down.
Increasing the area of the paddles speeds it up
Increasing the rotor RPM speeds it up
Increasing the aspect ratio (span/chord) of the paddles speeds it up.
Increasing the length of the flybar speeds it up.
This last point was something that Ken Rudd touched on in W3MH some time ago. However its not obvious why this should be the case so let me just give my reasoning for it. If we take one size and weight of paddles and fit them to a flybar that has been lengthened by say 10%. We :-

1) increase the moment of inertia (the flywheel effect) of the flybar. This means that the flybar will need a greater torque to impose a given rolling or pitching rate on it.
2) However, in putting the paddles further out we have increased the leverage that they have so that, for a given aerodynamic force on the paddles, we have a bigger torque.
3) In addition, by putting the paddles further out we have, for a given head speed, increased the airspeed of the paddles and thus increase the aerodynamic forces they produce.
Now effect 1) acts to slow down the response of the flybar, and it involves a square law so a 10% increase in flybar length increases the torque needed for a given roll rate by about 20%. However, effect 3) also involves a square law so, with the paddles 10% further out they produce 20% more force for a given cyclic pitch. So effects 1) and 3) cancel one another out. This leaves effect 2) which is linear and so a 10% increase in flybar length speeds the flybar up by 10%.

Ok

I am convinced my statement is wrong. Longer flybar on the Fury is less sensitive of center.
That also explained why my " FLY BAR " is so sensitive and I assume you guys with " LONG FLY BAR " do need help.

Christian..

WHO need the stinky Fly bar to do 3D, inverted or Tic Toc....?
You gotta get out of normal mode and see the sunshine...

I will hunt you down with a 25 foot tape measure, I assume you hover real smooth. We'll see.

Flybar length

FWIW; the math from Colin Mills article is correct, but I believe the interpretation of it is not. A longer flybar gives more flybar authority for the reasons stated in the article. The response time is longer, however; because of the time needed to accelerate the flybar and move it to it's new position. The calculations are correct for a steady state, but don't take into account the time needed to achieve a steady rate of movement, ie; to accelerate and move the flybar to a new position once commanded to do so. By lengthening the flybar, you've essentially created a larger gyroscope and it takes more time to move it out of it's plane of rotation. The eventual displacement and resultant ultimate cyclic authority will be greater, but it should theoretically respond more slowly. This seems to agree with my own observations that a longer flybar gives very good hovering stability and still retains excellent cyclic power. Steve.
