1. General Information
VBar stands for „Virtual Flybar.“ (In German it is called "VStabi“, from
Virtual Stablizer Bar). The VBar simulates the behavior of the flybar
and all its associated mechanical parts, so that these parts can be
entirely be dispensed with.
The VBar is not an autopilot! An autopilot can steer or hold the heli in
a given position. This is not what the VBar does. Rather, the VBar
simulates the expected behavior of a conventional rotorhead (which
includes a flybar). With the VBar, control of the helicopter’s movements
remains fully with the pilot. Errors in controlling the helicopter will
inevitably lead to crashes. There are several advantages of the VBar,
compared to a conventional rotor head. We will mention just a few of
the important ones here. Firstly, as the digitally controlled rotor head
has fewer mechanical components, weight and air drag are reduced.
Secondly, by changing the settings in the VBar System, it is much
easier to adjust the heli’s performance to the pilot’s individual
requirements. In a multi-blade helicopter, a mechanical flybar cannot
be used at all, so that the digital rotor head can supply all the
advantages of a flybar head.
How does the V-Bar work?
VBar is an electronic unit which is placed between the receiver and
the servos. It reads and analyzes the receiver signals. In addition it
registers the helicopter‘s yaw rates along all three axes (elevator,
aileron, and rudder) by MEMS sensors. All measurements are entered
into a mathematical algorithm, which outputs the desired values to
be transferred to the servos.
