TRVL. ADJ - TRAVEL ADJUST
Elevator-to-Flap Mix
S-21
Travel Adjust allows the independent adjustment of servo
travel for each direction of servo travel.
1. Highlight and select TRVL ADJ. in the FUNC.LIST to
obtain the Travel Adjust display.
2. Use the Selector to highlight and select each channel
and adjust the travel in each direction by rotating the
Selector. The direction of travel is changed by moving
the stick/switch/lever back and forth.
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 80% up elevator, the flaps
are mixed to give down flaps, causing greater up pitch
authority. For more detail on setting up snap-flaps, see
the setup guide on page S-66.
To access Elevator-to-flap mix, in Function Mode list,
rotate the Selector until
ELEFLP M is highlighted.
Press the Selector to access the Elevator-to-Flap mix
menu. Note that two elevator-to-flap mix values are
available,
Pos0 and Pos1 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.
Note: Position 1 always has priority over position
0. Press the LIST button to return to the Function
Mode screen.
