While a joystick feels more natural, it won't have the same deflections like a real heli stick. In most cases it is even less, which makes the heli in FGFS more difficult to control than the real thing. Usually the full control travel way of a real helicopter stick is between 6 inches and 11 inches depending on the helicopter. | While a joystick feels more natural, it won't have the same deflections like a real heli stick.

The deflections of a real heli stick can be also asymmetrical depending on the helicopter, while our joysticks always have symmetrical deflections. | The deflections of a real heli stick can be also asymmetrical depending on the helicopter, while our joysticks always have symmetrical deflections. | ||

That's the reason why on modern helicopters like the EC135 the attitude indicator is even mounted with a bank on the panel. | That's the reason why on modern helicopters like the EC135 the attitude indicator is even mounted with a bank on the panel. | ||

The following video demonstrates the ETL, or also called translational lift effect. The lift of the rotor will increase by passing a certain relative airspeed, usually about 20ktn. | The following video demonstrates the ETL, or also called translational lift effect.

'''Video: Hover Turns''' | |||
The following video shows how to turn the helicopter in a hover about a spot. | |||
This is quite difficult, as the helicopter tends to drift to the side due the tail rotor thrust. Not only that, the tail rotor is "stealing" power from or "giving" power to the main rotor. If you turn to the right with the BO 105 the helicopter will descend, turning to the left it will climb. | |||
