These keys are used to
move through the items
in this menu.

stick operation blinks)

* The blinking item is what is being set
Step 8. Setting the exponential adjustments: Exponential
is used to reduce the control sensitivity around center while still
providing full control authority when the control stick is full
deflected. Because the Ultra Stick
™
has large recommended con-
trol throws, it’s a good idea to give expo a try, even if you’ve
never used it before, to prevent over-controlling. In Basic mode,
press the Mode key until the “EXP” function appears on the
screen. Pressing the Cursor key will allow access of the aileron,
elevator, rudder and AB (throttle) channels. Toggling the respec-
tive dual rate switch will allow one of two expo values to be
stored. It’s recommended that a -30% expo be programmed for
aileron, elevator and rudder as a good starting point. Later after
several test flights you can fine-tune the control feel to your liking.
These keys are used to move through the
two submenus in the ELE-FL function.
Flap travel due to
DOWN Elevator stick
Flap travel due to
UP Elevator stick
Allowed flap travel Range: -100 to +100%
Initially set to 50%
1. Turn the ELE-FL function ON or OFF by pressing the (+) key (“ON” or
“OFF” displayed). Turn off (INH) the function with the (-) key.
Flap UP and DOWN travel input.
Push the elevator stick in the direction
you want to adjust and set the desired
travel with the (+)/(-) keys.
Press the (+) and (-) keys simultaneously
to reset to 50%.

Step 9. Elevator-to-flap mixing: Press the Advance Menu
keys simultaneously to access the Advanced Menu mode. Next
press the Mode key until “ELE-FL” (elevator-to-flaps) appears on
the screen. Press the (+) key to activate elevator-to-flaps. With
flap switch C in the up position (ELE-FLP), press the Cursor key
until the value is blinking. Then use the (+) or (-) key while
holding the elevator stick in the desired up or down position to
change the values so that up elevator gives down flaps and
down flaps gives up elevator. A value of 35% in both directions
is a good place to start.
Note: If the flaps travel in the wrong direction when elevator
is applied, reverse the value using the (+) or (-) key.
E.G., +35% to -35%. The ELE-FLP switch is used to turn on/off
this function.
