A -> R (Aileron-Rudder Mix)
A -> R (Aileron-Rudder mix)
This pre-programmed aileron-rudder mix allows you to slave a
certain amount of rudder movement with the movement of the
ailerons to gain automatically coordinated turns. In addition to
aileron differential, this mix reduces the yawing of the fuselage
when the ailerons bank the wing.
This mix is especially useful for making the turns of slower-flying
scale models appear more realistic.

Setting up a rudder-to-aileron mix
1) In the A-R screen, activate the function by pressing both
DATA buttons at once. The "Inh" symbol disappears and is
replaced with a percentage value (100% is the default).
2) Hold the right-hand joystick to the left, and use the - DATA
button to reduce the value to a reasonable mix to begin with,
say 25%.
3) You're not done yet, though-we have the same issue with
the stick we encountered in the end point adjustment (EPA)
screen.
If you move the aileron joystick to the right, the value goes
back to the default 100% setting. Hold the stick to the right
and reduce the value to 25% here as well.
4) Now watch the rudder move as you move the joystick right
and left-as the right wing's aileron moves up, the rudder
should swing about one-quarter of its travel to the right-and
to the left with left-hand stick travel.
The optimum value of the mix can only be determined by flying
the model: If the nose of the airplane yaws to the right when
you bank left, there is too little coupling-increase the rudder
travel value. If it veers to the left (with the bank) there is too
much
This program allows you to set a certain amount of
elevator-to-flap mixing so that the flaps (or flaperons if you've
activated this mix) move downward slightly when you pull back
on the elevator stick. This is a favorite mix for pylon racing and
3-D aerobatics as a downward flap movement combined with
up-elevator movement enables the plane to snap-turn more
quickly.
Setting up an Elevator-to-Flap mix
1) In the E-F screen, activate the function by pressing both
DATA buttons simultaneously. The "Inh" symbol disappears
and is replaced with a percentage value (100% is the default).
2) Now hold the right-hand joystick all the way back (for full up
elevator) and then, as you watch your model, change the
value to gain the amount of down-flap movement you want
at full up-elevator. You probably won't need more than 15%,
but only in-flight testing will tell you for sure.
3) Finally, push the stick forward and reduce the value to
0 %-you generally don't want the flaps going up when you
push the elevator stick forward.
CUT (Engine Cut Function)
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.
CAMB (Wing Camber)
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
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.

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).
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.
As always, you will likely have to change all these values
somewhat when you get the model up into the air.
