The flybar and all its associated mechanical parts in the rotor head are no longer indispensable components of the helicopter. Now this entire system can be replaced by an electronic set-up, the Virtual Flybar System (V-Bar). By setting parameters in a software module, pilots can control and modify in a very simple manner rotor head properties, such as, for instance, Bell / Hiller ratio or paddle weight. Just as with a Heading Hold gyro for the tail rotor function, you can now determine the cyclic speed for aileron and elevator control, which is then directly controlled by an electronic system. In 3D flying, the use of the V-Bar system expands the flight envelope: Compared to conventional, mechanical, rotor heads, the V-Bar system reacts much quicker and with much more agility. It is less susceptible to unwanted effects from gusts of wind. Moreover, the undesired internal effects of a mechanical system are completely eliminated: The helicopter will respond to the input in the most exact way possible. Digital operation means maximal control and ultimate precision! Imagine your heli in straight-forward or backward flight: A pressure sensor will measure flight speed continuously and adjust elevator input to the swashplate automatically. For scale pilots, the V-Bar offers new ways of dealing with multi-blade rotor head systems, which are typically very difficult to control. The V-Bar system allows pilots to set the rotor head up in such a way that the helicopter will show a high degree of stability. As a result, novice pilots will succeed much quicker, even with scale models. (Note: V-Bar is not an autopilot!) A further highlight of the V-Bar system is the integrated Heading Hold tail rotor gyro. This gyro is characterized by precise stopping performance and continuous yaw rate of the tail even in windy conditions, thus complementing the V-Bar's performance. The set-up of the tail rotor gyro is also carried out in the V-Bar software module.
