the throttle servo by pressing the Minus (–)
DATA INPUT
key. Verify the throttle stick
makes the servo move the carburetor opening
in the correct direction.
8. Now we’ll set the direction of the rudder
servo. When you move the left-hand stick
towards the CENTER of the transmitter (to
the right), the trailing edge or rear rudder
should move to the right. Check to make
sure!
If the rudder moves the wrong direction,
activate the opposite direction by pressing the
Minus (–)
DATA INPUT
key. Move the left-
hand stick left-and-right again and verify the
rudder moves the right direction.
9. If your model has retracts, set the correct
response direction when commanded by the
retract switch, using the same approach.
10. If you’re using a second aileron servo,
you’ll now set the left aileron servo direction
(otherwise skip this and the next step). This is
channel 6, and the ‘
6
’ should be flashing for
this command. When you move the right-
hand stick to the right, the aileron on the left
wing should move downwards. Check that
the left aileron moves the correct way! If it
does not, activate the opposite direction for
the aileron servo by pressing the
DATA INPUT
keys. Move the right-hand stick again and
verify the left aileron moves the proper
directions.
11. Go to the Flap Trim function (
FLTR
), and
input a percentage of zero (0). Then press the
CURSOR
key and activate the function. This
temporarily disables the flap knob so that you
can set aileron neutrals without regard to the
flap knob position. Later we’ll turn it back
on.
12. Now we will set the servo neutrals.
Center all the trims – you can tell when each
is centered because you’ll feel a small
indentation at the center. Once you have
centered all the trims, unscrew the screws
holding the servo arms onto the elevator,
aileron, and rudder (we’ll set the throttle
travel later). You will want to place the servo
arms on the output shaft so they are near
neutral — that is, about 90° to the servo case
sides or, if the servo is mounted sideways, 90°
to the pushrod (sideways mounting is not
recommended). This way you won't run out
of subtrim authority. Remove all the arms
that are in the way or interfere with your
pushrods.
Pushrod
Adjust the clevises on each servo pushrod to
get the position of each control to be as close
as you can to neutral (lined up with the
adjacent portion of wing or tail).
13. Now we’ll set all the subtrims to
electronically set the desired neutral locations.
To do so, get to the
STRM
menu by pressing
either
MODE SELECT
button repeatedly until it
appears.
Set the right aileron subtrim first. If the little
arrow is not pointing at channel 1, press the
one of the
CURSOR
buttons until it is (see
figure). Then, adjust the subtrim amount by
adding or subtracting with the
DATA INPUT
keys. When you have reached a place where
both ailerons match up with the fixed portion
of the wing, you are done. If you can’t get
