Simple Transmitter Setup - Electric Airplane, 5-Channel Receiver (ACGL Menu)Simple Transmitter Setup - Electric Airplane, 5-Channel Receiver (ACGL Menu)
16. If the throttle stick operates the speed control the wrong
direction, move over to Channel 3 by pressing the Cursor
Right key. Now the 3 should be flashing in the display.
Activate the opposite direction for the throttle servo by
pressing the Active/Inhibit (Clear) key. Verify the throttle
stick makes the motor turn on and off in the correct direction.
17. If you are using Switch SW-1 for throttle on-off, check that
the switch operates the motor in the direction you would like.
The UP position should be used for motor ON, and DOWN
for motor OFF. If it does not, reverse CH3 using the REV
menu as described above.
18. Now we'll set the direction of the rudder servo, if used.
When you move the left-hand stick towards the CENTER
of the transmitter (to the right), the trailing edge, or rear of
the rudder should move to the right. Check to make sure!
If the rudder moves the wrong direction, move over to
Channel 4 by pressing the Cursor Right key. Now the '4'
should be flashing in the display. Activate the opposite
direction for the rudder servo by pressing the Active/
Inhibit (Clear) key. Move the left-hand stick left-and-right
again and verify the rudder moves the correct direction.
19. Now set the CH5 aileron servo direction (otherwise skip
this and the next step). This is channel 5, and the '5'
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 CH5 aileron
moves the correct way! If it does not, activate the opposite
direction using the above procedures. Move the right-hand
stick again and verify the CH5 aileron moves the proper
directions.
20. Before we set the servo neutrals, we need to be sure that
all the trims are centered. Press both Edit keys to get to the
main menu, where voltage and time are displayed. Press
the Up arrow until the word TRIM appears. By moving each
of the four trim levers around, you can see their positions,
and move them back to zero for the next step.
21. Once you have centered all the trims, unscrew the screws
holding the servo arms onto the elevator, ailerons, 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.
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).
Setting Subtrims. Now we'll adjust all the subtrims to
electronically set the desired neutral locations. To do so,
go back to the programming menu by pressing both Edit
keys, then press the Up or Down arrow key repeatedly until
STRM appears.
22. Set the subtrims for CH1 and CH5 ailerons, elevator, and
rudder following the instructions given in steps 25 - 32 in
the aerobatic setup instructions. Remember your second
aileron servo is plugged into CH5.
23. Servo EPA (End Point Adjustment). Set up the servo
travels for each channel following the instructions given in
steps 33 - 43 in the aerobatic setup instructions.
24. Dual Rates and Exponential Functions. You can use the
exponential function to make the aileron and elevator
responses less sensitive around neutral, so that your racer
reacts smoothly for mild control inputs, but reacts strongly
when you command a lot of stick. You can adjust the
amount in flight by flipping switches. Exponential functions
make the response slower around center and larger away
from center. You may also use dual rate to adjust the total
travels, but keep them linear.
Set up dual rates following the procedures given in steps
48 - 53 of the aerobatic aircraft setup instructions.
NOTE: if you set any of the dual rates to 0%, you will have ZERO
CONTROL and LOSE CONTROL OF YOUR AIRCRAFT when the
switch is in that position. DON'T DO IT!
25. Airbrake setup using CAMB. You can get airbrakes by
flipping a switch to raise both flaperons and add elevator to
maintain trim. This configuration increases the drag, making
the landing approach steeper to help make safe landings in
small fields.
With CAMB on, it is possible to lose some aileron
effectiveness. Be sure to test the landing settings at altitude
before trying it on a landing approach. You should spend
some time fine-adjusting the elevator travel so that there is
no trim change when CAMB is on.
26. Press one of the Up Down Edit buttons until the CAMB
window appears, as shown. Activate it using the CLEAR
button. The CAMB mode is OFF unless the FLT MODE
switch SW-4 is forward. (You can change this switch in the
SWITCH SELECT menu.)
27. Hit the Cursor Right key one time to get to the Ch1 preset
menu. Press the Data +Increase key to input a preset
value for the CH1 aileron. Start out with a moderate value
and increase it after you've seen how the model behaves.
34. Now, you'll define the mixing percentage. Notice that the
mixer starts with 100% on both sides, which is WAY too
much. Move the elevator stick down and press the Clear
button, zeroing the percentage. Move it up and repeat.
Now both sides are set to zero percent.
35. You'll probably want to input down flap for up elevator only.
Move the elevator stick up and press the Data +Increase
until you can see which way the elevator moves; if incorrect,
press the Data -Decrease key until the plus sign changes to
minus sign. You'll end up with a number for up elevator
direction, and zero for the down direction. Start with only
5-10% mixing on the UP side until you know how much you
need from actual test flying. Too much droop increases
drag and slows the model down.
36. Be sure you understand how to set the switch to turn PMX1
on and off, since you only want this on during racing. Later,
after you fly the model you may fine-tune the amount of
aileron travel for tighter turns.
Use the other mixer to set up the droop of the second
aileron, CH5, in the same way. In this mixer, master = CH2,
slave = CH5. Set the mixing percentages so that both
ailerons droop the same amount, or else your model will
roll when you pull elevator!
This introduction just scratches the surface of the
capabilities of your Optic system for a five-channel electric
model. Please read the manual so you'll know what other
features you can take advantage of. We hope you enjoy
using your Optic system!
28. Press the Cursor Right key to move the arrow over the
numeral 2. Now press the Data +Increase key to change
the percentage the elevator moves to. This should be set a
very small number, as it will affect the trim considerably.
Don't use too much or it could crash your model.
29. Press the Cursor Right key one more time, and you may
now input the second aileron's CH6 setting. Set it to match
the CH1 servo's travel.
30. If you want this airbrake function to be a proportional control
using the left slide lever, use the CROW menu instead of
the CAMB menu. See the setup instruction for more
information on the CROW menu.
31. Elevator->Flaperon Mixing: you may want to set up your
model so that when you pull elevator, the two ailerons
droop for tighter corners. This may be done with
Programmable mixers. You will use both of the
programmable mixers (PMX1, PMX2) for this feature.
For a little down flap when you pull elevator, set the master
channel to be elevator, and the slave to be aileron 1 (CH1).
32. To program this mixing, first get to the PMX1 window.
Press one of the Edit Up/Down keys until you see PMX1
displayed. Then press the Active/Inhibit (Clear) key to
activate it (a flashing ON or OFF will appear, depending on
the position of the selected ON-OFF switch, which turns
mixer #1 on and off).
33. Next, press the Cursor Right key once to select the master
channel (MAS flashes on and off), then press the Data
+Increase key until the little arrow moves over the
numeral 2, indicating CH2 (elevator) is the master channel.
Press the Cursor Right key once (SLV flashes on and off),
then press the Data +Increase key until the little arrow is
under the numeral 1, indicating CH1 (aileron 1) is the slave
channel.
