Hey I've been told that the flybar is there to keep the rotor head more stable but can anyone expound on that? What are the aerodynamic forces in action and what could happen if I just took it off?

What goes up must come down...and when it does it'll probably be expensive.

Depends on the heli, the bigger they are the better they tollerate not having a flybar without a stabilizer system.

It's mostly about inertia, the more spinning weight the more inertia, the more stable the heli.

Google Colin S Mills and read his rotor head articles if you want to go into detail.

Thats why flybarless helis with a device like a VBar are nuts in cyclic if you want them to be.

Think of the flybar as a buffer for the cyclic. Without it the blades would be directly attached directly to the swash and the heli would be VERY sensitive. The flybar is between the swash and the blades and tames things down.

The flybar gives the helo power steering on the flight controls in my opinion. With out it your inputs on the sticks would be very responsive "Twitchy" just my 2 cents on the subject.
