S-20
A Flight Mode represents an aircraft configuration (camber
position, trim positions, Dual Rate/Expo settings, program
mixes, aileron differential value, etc.) that is programmed to
optimize the aircraft for a particular task. Up to 5 flight modes
are available in the 12X that include Launch, Cruise, Speed,
Thermal and Land.
The objective of programming Flight Modes is to provide
the ability to select a switch position to activate a collection
of settings that are optimized to perform a particular task.
For example, the launch mode is typically set up to give the
following:
• The flaps and flaperons are preset with positive camber to
give more lift during launch.
• An elevator preset trim position that gives the best climb is
programmed.
• A high rudder rate with reduced exponential to give
authoritative steering control on launch is desired, while
the elevator and aileron rates are set to give a medium
response.
• Aileron-to-rudder mix is turned off, as are landing flaps and
elevator-to-flap mix while camber adjustment of the side
lever is programmed to give proportional camber changes
to allow for last minute adjustments based on wind and
winch conditions.
• Aileron differential is set at 50%.
All these (and many more) programming parameters can be
selected by simply moving one switch. At the top of the launch
you prepare to zoom by switching to the cruise mode. A single
flip of the switch neutralizes the trailing edge while giving the
correct elevator trim for cruise. Rudder-to-elevator and elevator-
to-flap mixes automatically turn on the programmed values
and the aileron differential is now at a much higher 75% for
more coordinated thermal turns. At the flip of a single switch
you’re ready for a zoom launch and for hunting thermals! And
remember there are 3 more flight modes available. Once you
start using flight modes, you’ll wonder how you ever flew
without them.
Most of the functions found in the 12X that are switch
selectable, including Flaperon Mix, Servo Speed, Camber
system, Differential, Aileron to rudder mix, Elevator to flap mix,
Flap rate, Brake system, trims and programmable mixes, can be
assigned to one or more Flight Modes. This provides the ability
to have up to 5 completely different aircraft configurations that
are selectable in flight using switches.
Five Flight Modes are available in the 12X system. When 3
Flight Modes are activated, they are selected during flight by
using one of seven 3-position switches (Flight mode switch,
Motor switch, Butterfly switch, Rudder D/R switch, Elevator D/R
switch, Aux 2 switch, Aileron D/R switch or Inhibit). To activate
the 2 Extra flight modes (5 flight modes in total), the 4th and
5th flight modes are assigned to one of the following switches
( Flight Mode, Rudder D/R switch, Elevator D/R switch, Flap
Switch, Aux 2 switch, Aileron D/R switch, Inhibit). Flight mode
switches are selected and activated in the Device SEL function
in the System menu. Once Flight Modes are activated, the pilot
has a choice of using the Flight Mode switch to select up to
5 Dual Rates and Exponential settings for each of the primary
controls (ELEV, AILE, RUDD), or Dual Rates and Exponential
settings may continue to be controlled by the 3 individual Dual
Rate switches. All other functions that can be activated by a
switch can be assigned to 1 or more Flight Modes when Flight
Modes have been activated.
