Helicopter Controls
I broke into my old Logitech WingMan
Extreme 3D joystick and removed the
10k pots that controlled the rudder and
throttle. Using 1/8"  stereo jacks, I
soldered new wires to the circuit board
where the pots were connected. The
spring that returns the joystick to center
was also removed for more realism.
Then using external pots, I built the anti
torque pedals and collective as shown.  
Both the collective and pedals plug into
the joystick using standard audio cables.
The joystick base is a simple wood and
metal support that slides into the seat
bracket. Now flying Helicopters in FS is
much more realistic!
