Ok, I feel like a complete retard for asking this but what exactly does the flybar do? I understand the rest of the mechanics of an RC heli but Im not sure about the flybar.

The paddles on the flybar actually command the rotor disk what to do. When you are manupulating the cyclic stick on the transmitter, you are actually making inputs to the flybar paddles. This in turn tells the rotor disk where to go.

Ok I understand now. Thanks guys. My only question is if the cyclic is too sensitive without it, why cant you just reduce the linkage ratio from the servos to the swashplate?
How well does a heli fly with a four blade head? Do they get real touchy?

The flybar is a steerable gyro,without it the machine becomes very unstable in FFF due to pitch up caused by the difference in lift on the advancing blade vs the retreating blade exceeding the ability of the system flapping to compensate. They are flyable but can do some interesting acrobatics with no pilot input
