=== Control hardware ===
=== Control hardware ===
The parameters for FlightGear helicopters are not completely optimized and thus the performance between model and original may deviate. On the hardware side I recommend the use of a good [[joystick]]. A joystick without centering springs is recommended for cyclic control. You can achieve this with a normal joystick by removing or disabling the centring spring(s), or you could use a [[force feedback]] joystick with a disconnected voltage supply. Further, the joystick should have a “thrust controller” (throttle). For controlling the tail rotor you should have pedals or at least a twistable joystick; flying helicopters by keyboard is very difficult. ('''hint:''' Flightgear supports more than one joystick attached at the same time.)
'''Stick and Pitch control:'''


If using a mouse it's recommended to turn off auto-coordination:

You have to turn off auto-coordination, as you need full controls for the tail rotor:

* through command line or using [[FGo!]]: omit <tt>--enable-auto-coordination</tt> (which is the default).

'''Joystick vs Mouse'''
A mouse can be also used, but Joystick and mouse has both advantages and disadvantages.
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.
The deflections of a real heli stick can be also asymmetrical depending on the helicopter, while our joysticks always have symmetrical deflections.
The mouse won't feel natural, but you can change the control travel in mice.xml to your need. By decreasing the <factor> you can increase the control travel way and having less sensitive controls, which might improve the handling.
'''Keyboard'''
Flying helicopters by keyboard is not possible, as it won't provide sensitive enough control!
