S-34
Elevator-to-Flap mix is normally used to give several degrees
of down flap when up elevator is applied. This gives more pitch
authority than would elevator alone, and is commonly used
for slope racers to improve high-speed turns and in thermal
sailplanes to allow increased maneuverability for tight thermal
turns. An offset is available that allows the programming of
snap-flaps. With snap-flaps, no flap mixing occurs during small
to medium up elevator inputs, but at about offset point of up
elevator, the flaps are mixed to give down flaps, causing greater
up pitch authority.

To Access Elevator-to-Flap Mix
1. In Function Mode list, rotate the Selector until ELE
FLP M
is highlighted. Press the Selector to access the Elevator-to-
Flap mix menu.
2. Note that Elevator-to-Flap mix values are available for each
active flight mode and the Elevator-to-Flap values can be
independently adjusted up and down. Also the offset (the
stick position where the mixing changes from up to down)
can be adjusted. This offset allows the programming of
snap-flaps, a common sailplane function that gives greater
full up elevator pitch authority for tighter turns. If you
choose to program snap-flaps, the offset adjustment range
is -200 to +200. Negative values move the offset in the up
elevator direction. Switches are available at the bottom of
the screen that allow the selection of Pos0 or Pos1.
