As always, you will likely have to change all these values
somewhat when you get the model up into the air.
CUT (Engine Cut Function)
CAMB (Wing Camber)
This program allows you to initiate a mixing of the ailerons
with flaps or Flaperon to camber the trailing edge downward
or reflex it upwards.
Camber changes the airfoil to create more lift as you slow the
aircraft down for landing or to make a scale model fly more
slowly and realistically. You will also be able to set the travel of
the elevator on this menu screen to compensate for the model's
tendency to nose up when the flaps and ailerons droop down
together.
Setting up wing camber and elevator compensation
2) Start with the SW-3 switch in the middle position.
Now move it toward the front of the case and you'll notice
that the "Inh" symbol comes on and the "NOR" symbol in the
black box changes to "ST-2". Activate this switch position by
pushing both DATA buttons simultaneously.
Now we are ready to feed in values for the ailerons and
elevator (for pitch compensation) when you pull the switch
toward you. (You could, of course, choose to activate the
mode with the switch pushed all the way back (ST 1) if that is
more intuitive for you.)
3) Move back up one screen with the EDIT button to the CAMB
screen.
4) With the SW-3 in the middle, "NOR" position, check to be
sure that the values for channels 1, 2 and 6 all read 0%.
Now pull the switch toward you-"ST 2" appears instead of
"NOR"-and use a DATA button to set the downward travel
value for the right-hand aileron to 25% (+ or - depending on
your servo orientation.)
5) CURSOR over to channel 6 and set the left-hand aileron to
deflect 25% down as well.
6) To set a bit of downward compensation in the elevator travel
(we are assuming your airplane will likely nose upward when
the camber is activated), CURSOR over to channel 5 and set
15% of downward deflection.
1) To use the ailerons as flaperons to slightly droop down in
unison to camber the wing we first need to get into the FLT C
screen in order to put the flaperons action on the
three-position SW-3 "FLT Mode" switch on the upper
right-hand top of the transmitter case. Use the right-hand
EDIT button to move down to the FLT C screen.

CUT (Engine Cut function)
In this screen you can set the throttle's servo travel value
(you can also choose the direction in the program) so that you
can immediately cut off the motor when the engine is below
half throttle with a push of the "Eng Cut" button located on the
upper right-hand corner of the transmitter case.
Setting the engine cut function
1) In the "CUT" screen, un-inhibit the program by pushing both
DATA buttons-a percentage value comes up on the screen
(default is 0%).
2) Use either DATA button to change the value to a setting
(you can go positive or negative up to 75%) that moves your
throttle servo to the point where its pushrod fully closes the
motor's carburetor. (You activate the servo cut movement by
pushing the "ENG CUT" button on the upper right portion of
the transmitter case.)
3) Watch the servo movement on your model carefully:
You don't want to overdo the travel value or you'll stall the
servo (you'll probably hear it buzzing if its stalled-which
creates a drain on the on-board battery and a potential
over-heating problem for the servo).
