Lets say you want to use a three position switch for the flaps on Channel 7:

1. Go to the Parameters and assign the the three position switch to channel 7.

2. Set the end points on channel 7 to only 50% of their initial value.

3. Install the flap servos setting the mid point on the flaps the neutral point on the servo. This is done mechanically by the length of the contorl rod between the servo and flap horn.

4. Go and set the channel 7 end points so that one end gives you full flap deflection and the other end gives no flap deflection for regular flying.

Now when the switch is in say the up position, there is no flap deflection; when in the center there is mid flap deflection, and in the down position there is full deflection. Use the servo reverse function to set which switch is no deflection and full deflection.
