Knowledge base Vortex VX1 Fine tuning

Question #143
How can I make the helicopter flip and roll faster?

The easiest way to make the helicopter more agile is to load a more aerobatic preset using Setup::Style Wizard. You may also manually modify the parameters described below.

The Vortex operation is based on a sophisticated hybrid rotor control system that seamlessly combines a mathematically accurate flybar simulation with modern digital control algorithms. Understanding this concept is essential in order to fine tune the Vortex for your flying style.

Style - In traditional flybar systems the flybar is the limiting factor for the flip/roll rates of the helicopter. Similarly when the Style parameter is set near 0% (flybar simulation side) the helicopter will flip and roll slower as its flight behaviour is predominately controlled by the simulated flybar. Setting the Style to a higher percentage brings in more control authority via the digital stabilisation algorithms. The helicopter will achieve faster flip/roll rates, however at the same time it will start to feel more "robotic" in flight.

Paddle Response - This parameter is equivalent to controlling the weight of the paddles. If a traditional flybar system when the paddles are lighter we can achieve faster roll rates. Doubling the Paddle Response parameter has the same effect as halving the weight of the paddles. However lighter paddles also make the helicopter less stable in hover so you may consider using the Paddle Dynamic parameter instead.

Agility (aka Paddle Dynamic) - This parameter controls the weight of the simulated flybar paddles in response to cyclic stick. At neutral cyclic the paddles weight is controlled by Paddle Response but as the cyclic stick moves away from centre the paddles become lighter thus allowing stable hover but also faster roll rates. A higher percentage of Paddle Dynamic results to the simulated paddles becoming lighter.

Gain (aka Flybar Ratio) - Defines the mixing ratio between the simulated flybar and main blades. It can therefore also be seen as the rotor stabilisation gain. The default mixing ratio 46% means that the main blade pitch changes by 4.6° when the simulated flybar tilts 10°. As the flybar mixing has a significant effect on the the main blade pitch a higher gain also provides faster flip/roll rotations. However oscillations may start to appear if the value becomes too high.
