AIRCRAFT SETUP INSTRUCTIONS (GENERAL 120 CLASS STUNT PLANE)
The aircraft setup procedure presented below
uses a F3A-class model as an example. You may
use a similar procedure to set up your own model,
but your setting’s numbers and percentages will
probably be different.
1. Enter the Model Select menu (MODEL) by
pressing the two BASIC keys, then pressing one
of the MODE keys until “MODEL” appears.
Press the right (>)
key to get to the model
select function (SEL) and choose a vacant model
memory with the plus (+) and minus (–) keys.
Select it by pressing both the
keys at
once. The following instructions refer to
memory #5.
2. Press the right (>)
key twice to get to
the model name function (NAME, p. 37). Use
the
and
keys to spell out the
name that you wish to appear on the screen, one
letter at a time.
3. Enter the Parameter (PARA, p. 31) menu by
pressing the down MODE key twice. Use the
left (<)
key to select the model type
(TYP) function and verify that ACRO (aircraft) is
selected. (If it isn’t, select ACRO by pressing the
plus or minus
keys until it appears,
then pressing both
keys to select it.)
WARNING: selecting a different model type will
erase the settings in the model memory. BE
SURE you’re in the correct model memory before
selecting a new model type.
If necessary, go to the modulation (MOD, p.
34) menu to select the proper mode of
transmission (F is for FM/PPM transmission, and
C is for PCM). This should be set to match your
receiver. If you make a change, it won’t take
effect until you cycle the power off and on again.
4. Next, turn on the Flaperon function (FLPRON,
p. 45) in the Advance Menu.
To do this, press both ADVANCE buttons
simultaneously, then press the MODE button until
“FLPRON” appears in the display. Activate by
pressing the plus (+)
key (“ON” should
appear flashing in the display.
Connect the right aileron servo to receiver CH1
and the left aileron servo to receiver CH6.
Note that you can get differential by adjusting
the up and down motion of the two servos in the
FLPRON menu. If you don’t need the flap
effect, you can use the AI-DIFF menu (and plug
the servo into the receiver CH7 output.
5. Check that each servo moves the proper
direction. The aileron servos should move in
opposite directions for aileron stick motion, and
the same direction for flap control. If not, use the
Reversing function (REVERS, p. 30) in the Basic
Menu to set the proper throw directions for each
servo. Also check elevator, rudder, throttle, gear,
and any other servos.
6. Set the basic travels with the ATV function in
the Basic Menu (ATV, p. 26).
Aileron settings: the left and right aileron travel
should be limited to roughly 9/16” (14-15
mm). If necessary, adjust CH1 and CH6
with the ATV function. Choose a location on
the servo arm so that the throw is adjusted in
the 90-100% range.
Elevator setting: adjust the elevator travel to
roughly 9/16” (15 mm) with the ATV
function.
