Sailplane- GLID Mode
The GLID mode is intended for multi-function sailplanes.
The program software was developed by some of the
world’s leading sailplane pilots and offers a level of
sophistication not found in any other sailplane system.
Up to 5 flight modes are available, each allowing virtually
every parameter to be individually adjusted. Active
flight mode digital trims allow in-flight adjustments of
camber, elevator, rudder and aileron. Trim settings are
automatically stored and recalled in each individual
flight mode. Following is a list of sailplane specific
programming menus and their primary functions:
SYSTEM MODE GLID FEATURES
• Trim Step–Allows the trim authority to be adjusted
or even turned off.
• Device Select–Flight modes, switch and lever
locations and functions are programmed
in this menu.
• Wing Type–Allows the selection of V-tail and dual
or single flap servos.
FUNCTION MODE GLID FEATURES
• Elevator-to-Flap–Allows two values of elevator-
to-flap mixing with independent up and down
adjustments. Offset allows snap flaps to be
programmed and the mix can be automatically
selected in any desired flight mode or via several
switch options.
• Aileron-to-Flap–Allows two values of aileron-
to-flap mixing with independent right and left
adjustment. This mix can be automatically selected
in any desired flight mode or via several switch
options.
• Aileron and Flap Differential–Separate differential
values (5) are available in each flight mode
including reverse differential (for landing). Aileron
and flap differentials are independently adjustable.
• Camber Adjust Delay–A delay of up to 2 seconds
can be programmed for each individual flight
mode such that when switching flight modes, the
camber and elevator presets transition smoothly. A
break-off delay allows an elevator stick position to
be used to override the delay, useful during launch
when switching from launch to cruise mode for a
zoom launch.
• Camber Mix–Allows individual up and down
flaperon and elevator values for each of the 5 flight
modes to be adjusted via the side lever.
• Aileron-to-Rudder Mix–Features separate right
and left mix values for each of the 5 available
flight modes.
• The Butterfly Menu–Provides 2 settings for flaps,
flaperons and elevator values operated using the
spoiler stick. Each value can be selected via flight
modes or several available switches.
• Flap Rate–Allows the flap camber up and down to
be adjusted independently in each of the 5 flight
modes via the side lever(s).
• Programmable Mix 1–Spoiler-to-elevator curve mix
allows non- linear elevator compensation when
landing flap (butterfly/ crow) is deployed. A
6-point adjustable curve allows precise elevator
input throughout flap travel avoiding unwanted
pitching during landings.
• 2 Timers–Are available and can be programmed as
count up or down, and are assignable to various
switches and buttons.
• Active Digital Flight Trims–Allow presets of
elevator, camber, rudder and aileron to be adjusted
in flight and are automatically stored and recalled
in each of the 5 flight modes.
Note
: The following section contains in-depth
details regarding each of the available programming
functions. If you’re just getting started, you’ll
likely find it easier (and we recommend) using the
programming guide for 6 servo sailplanes on page
S40. This step-by-step guide leads you through a
typical 6-servo sailplane and even gives the key-
strokes necessary to set up a sailplane, including
flight modes, butterfly and side lever camber
adjustment. We recommend referring to the section
below when a more in-depth understanding of a
specific programming feature is desired.
