I. INTRODUCTION
Both the hardware and software for the
micropro 8000 transmitter havebeen developed
by Emulation Electronics, in conjunction with
Ace R/C, and is manufactured under license
agreement between the two parties. We would
like to thank Marty and Tom Hendrickson of
Emulation Electronics for their considerable
talents and total commitment to this project.
WARNING AND DISCLAIMER: Improper use
ofthis unitmaycause serious personal injuryto
yourself, to others, or result in properby damage.
The user is urged to read and understand the
information contained before operating the
equipment. Prudent and reasonable conduct
when operating this radio system is requested by
the manufacturer.
Ace R/C, Inc. assumes no responsibility for
accident, inJury, property damage, or death in-
curred as a result of any use of this equipment
whatsoever. The user accepts the responsibility
to comply with all safety requirements, includ-
ing, but not limited to, those established by all
federal, state, and local governmental agencies,
the regulations of the FCC (Federal Communica-
tions Commission) Part 95, and to abide by the
rules and recommendatlons of all non-govern-
mental bodies related to the use of this equip-
ment. including, but not lirnited to, those set
forth by the Academy of Model Aeronautics.
You are about to embark on an exciting
adventure in radio control technologr. The
micropro SOOO ls an R/C transmitter that pos-
sesses the awesome power of modern micropro-
cessor computer-controlled circuitry, coupled
wittr software that has been developed and re-
Ilned to apointwhereyou, the user, canharness
the power of the computer with ease, comfort,
and simplicity. You will soon flnd out this
transmitter is so advanced, it's simple.
With this system, you wlll not be intimidated
by the complodty and power you are about to
unleash at your fingertips: you will only enjoy
the advantages brougtrt to you by state-of-the-
art electronics and American ingenuity and
thought that has made Ace R/C a leader in R/C
since 1953. Don't be afraid to orplore all of the
possibilities of the micropro system. At every
step of the way, we have installed the capability
foryou to recalibrate or clearwhateveryou have
done so you can get back to 'square one" and
start over. Wtren dealingwith the programming
of the system, you can't "break" anSrthing, so
don't hesitate to ocperiment.
Poge #3

These instructions assume that you are an
erperienced R,/C'er and know the basic opera-
Uon of a typical radio control system. We will
only provide the speciflc tnformation necessary
for set-up and use of the micropro transmltter.
Nomenclature used will be for flxed wing air-
planes: if you are using the transmitter in some
other application, you will need to translate
accordi:e$y.
One thing we ask of you: PLE \SE READ THE
INSTRUCTIONS thoroughly before you pick up
the phone and call us with a question. Hope-
fully, all questions have been covered: but, it
may take a bit of reading and orperimenting on
your part.
II. GETTING TO KNOW
YOUR micropro
A. The Batteries: Charging and
Changing
Your micropro transmitter is equlpped with
rechargeable 8OO mah/9.6v (etght cell) ni-cd
batteries. Under normal operation, you can
orpect four to six hours of operation from the
batteries before needing recharging. If you have
purchased a transmitter by itself, a suitable
charger will need to be obtained to charge the
batterles and the furnished 0.10" pin charge
plug will need to be installed (Ace P/N CCO84).
Refer to Illustration I for hookup. Make sure you
malntaln proper polarity. Heat shrlnk tubtng ts
provided to insulate the solder connections.
Technically, the overnight charge rate for the
8OOmAhbatteries is SOma for 12- 14hours, but
there is some leeway here for successful charg-
ing. Most chargers furnlshed with a radio sys-
tem charges the transmitter at 5O ma (which
would be the case if you bouglrt a complete
system). At the standard 50 ma rate, you will
need to charge the batteries 24-36 hours for the
initial charge, and about 18-20 hours for all
subsequent charges. The transmitter should be
recharged after each flying session or, if the unit
hasn't been charged in over a week, it should be
recharged before use.
If you have a variable rate charger, you can
Poge #4
charge the batteries at the overnight charge rate
(8O ma) and ttrey will be fully charged in I2-I4
hours. (Charge 24 hours on thevery first charge
cycle.)
Note: at the overnight charge rate or less,
leaving the batteries on for a couple of days won't
hurt anything, so don't worry if you forget to
unplug batteries after the prescribed tJme.
If you want more lnformatlon on the care of
Ni-cd batterles, Ace has a 'Battery Baslcs'video
tape (Ace P/N SOG1 l) or written Ni-cd Data
Sheet (free, send a S,\SE) which orplains the
details of nt-cds including cycling. We manufac-
ture a whole line of nt-cd chargi:eg and rycling
equipment to fit any need. Call us for details.
Because of the multiple airplane memory
and the possible need for more operation than
the batteries can supply, your micropro has a
removable, replaceable, "quick-change" battery
pack.
To access this pack, as well as the RF Deck
(see next section), the transmltter has a snap{n
back. Just press lre on the stdes ofthe transmttter
and the back will easily come off. Do so, and
notice that the batteries are connector wired
with a three pin Deans connector palr and are
attached to the back with Velcro. To remove,
simply unplug and peel the pack off the back.
Additional battery packs are avallable from Ace
R/C (P/N 38K8OOM), or you can make up your
own serles wired 8 cell nt-cd packs with a Deans
3 pin female connector, heat shrtnk tubing or
electrical tape, and readily avatlable self-adhe-
sive Velcro. Please don't attempt to make up
your own packs unless you are con_fldent you
have the tools and capabilities to do so.
After you have installed a freshly charged
pack, carefully snap the back on, making sure
the pack and BOTH RF Deck connectors arc
securely plugged tn.
NOTE: this transmitter's memory ls 'non-
volatile"; that means that loss of battery power
through discharge or disconnection doesn't af-
fect anything so don't worry about losing your
set-ups by disconnecting the batteries, lt won't
happen.
B. The RF DecK
The portion of the micropro transmitter that
broadcasts the commands to the receiver ts the
RF Deck. It is on a specific frequency or channel
as indicated on frequency plate that is orposed
on the outside of the back. The crystal in the RF
deck is also liabeled with the frequency/channel.
The RF Deck is attached to the transmitter's
snap-onbackbymeans of two 2-56bolts, which
also hold the frequenry plate in pliace. TWo
WRE = POSITIVE (+)
CHARGE PLUG

Deans connectors (a two and three pin) make the
electrical connections. Wtren plugging these
connectors back in, make sure you observe the
proper polarity on the three pin connector; the
two pin connector has no polarity and doesn't
make any difference how it is plugged in.
Additional RF Decks are available from Ace
R/C. (P/N 11G9M)
C. The Two micropro Modes
Your micropro runs in two basic Modes:
RUN and CALibrate. You will have the trans-
mitter in the RUN Modewhenyou are flyingand
in the CAlibrate mode when you are setting up
the transmitter for a particular airplane. The
mode is determined by the RUN/CAL switch
located behind the antenna. For safety, this
switch is a locking type switch; the bat on the
switch has to be lifted to be able to switch
between ttre two modes.
D. The micropro LCD Display
The LCD digitat display on the front of the
transmitter is your communlcations link
throughout your micropro experience. It will tell
you all you need to know about using and setting
up this transmitter and will displayyour lnterac-
tions with the transmitter as you program its
powerful computer.
As we proceed through the instructlons, we
will show you how the display reacts to your
inputs.
III. THE RUN MODE
VOLTMETER & BAfi. TIMER AIRCRAFT SELECTED
ll,lU $3--ll ll 0:[0
MIX 1 MIX 2 MIX 3 FLIGHT TIMER
In the RUN mode, you have a ma:dmum of
eight channels of command available to you.
The normal four stick channels (three neutraliz-
lng and one racheted): Elevator (Ch. l), Aileron
(Ch. 2), Rudder (Ch. 3), and Throttle (Ch. a);
Channel 5, which is a two position switch nor-
mally used for retracts; Channel 6 and 7, which
are proportional levers, and Channel8, a three
position switch. If you are operating a seven
channel receiver, Channel8, when used with the
mixer function, can be used to give you presets
for various purposes which we'll cover later.
If for any reason, you wish the transmitter to
broadcast less than eight channels, it can be
changed to 4, 5, 6, or 7. If less than eight
channels are selected, the switches or levers that
normally control those functions are simply
ignored unless you use the unused channel as a
Mix'FROM" channel. Thatwillbe ocplained ttre
Special Functions section of the instructions.
Other features t]lat are available in the RUN
mode are:
A. Dual Rates
Dual rates allow the user to have two different
sensitivities on the three neutralDing stick
controls (Elevator/Aileron/Rudder.) Each pri-
mary control stick has a toggle switch associated
with it that allows the user to select eittrer rate.
The rates are determined by the endpoints that
are set in the C,Alibration routine.
The dual rate can be either less than, equal
to, or more than the normal rate, depending on
your preference. If exponential rate is enabled,
itwill be turned onwhen ttre switch is in the up
position.
B. Exponential Rates
THE EXPONENTIAL CURVE
E>rponential Rate ls exponential currring of
stick travel versus servo motion. On the three
neutralizing channels, exponential rate'soft-
ens' or desensitizes the stick around neutral.
Whenyou are flyingwith the exponential rate on.
movements of the stick around neutral will
result in little servo motion. With experience,
erponential rate makes it much easier to fly
smoothly when flytng sensitive airplanes.

Poge #5

Exponential rate on the throttle stick desen-
sitizes the stick at low throttle so stick movement
versus RPM response can be more of a one-to-
one relationship because most carburetors have
non-linear response.
The amount of oqponential rate is deter-
mined for each channel in the CAlibrate mode.
It can be set from "O" (which is ofO to "9' (whtch
is the most available). On the three neutralizing
channels, the Dual Rate switches serve double
duty and will engage or disengage o<ponenttal
rate. When the dual rate switch is in ttre up
position, ttre orponential rate curve you have
chosen is turned on. T?re endpoints of servo
travelwill remaln the same as theynormally are
for this switch position.
If exponential rate is enabled for throttle, lt is
always on.
C. Mixing
1. Universal Mixing
The micropro offers totally universal mldng.
You will ffnd when you get to Midng in the
calibration section of the iestructions, you can
program limifless midng capabtlities for any
imaginable requirement.
Up to twelve mldng tasks can be assigned to
mi:dng switches in order to have the capabilityof
turnlng the mixing tasks on or off. Essentially,
there are three mldng switches. "Mix I' and
*J&fixz" switches are accessible in normal opera-
tion and can be turned on and off as desired.
"Mix 3' is always ON. You will assign mfdng
tasks to *Mlx 3" that you never want to turn off
when you are flying. Up to four mldng tasks can
be assigned to each of the three switches for a
total of twelve.
(Note: tf you want to be able to turn'Mix 3"
on or off, it can be done by installing another
switch in the transmitter. Contact the factory for
details.)
The LCD Display wtll indicate the status of
ttre mixing switches. If an "M' appears in the
"Mix 1", "Mix 2", or "Mix 3" locatlons, that
particular switch ls on. You wlll note that the
'M' is always displayed for "Mix 3', indicating
that it is always on.
2. Pre-Programmed Mixing
As a short cut, there are ttrree mfidng func-
Uons that are pre-programmed in your micropro
that you can access. All of these are always on
and not affected by the mixing switches.
Aileron Differential: Thls feature allows you
to control the amount of up versus down travel
on each individual aileron in order to do away
with the adverse yaw caused by the ailerons
moving downward, particularly in $iders and
high winged powered planes.
V-Tail: This feature mixes elevator into rud-
der and ru dder back into elevator for a a/-Tailed"
airplane appltcation.
Elevon: The best orample of Elwon mi:dng is
a delta winged airplane tllat uses the two control
surf,aces at the rear or the wing for both pitch
(elevator) and roll (ailerons).
D. AutoTrim
AutoTrim allows you to trim ttre aircraft by
only using a push button switch and not removing
your hands from the sticks. AutoTflm is activated
by pushing theAUTO TRIM switch which moves
the servos in the same direction in which the
sticks are displaced from neutral. This movement
of the servos will be at a slow and controlled rate
(this is called slewtng) so there will be no quick
movement of the aircraft. AII three neutralizing
channels (Elerzator/Aileron/Rudder) are effected
by AutoTrim if their stick is displaced.
For gross trimming on the inittal fltght of a
new, out-of-trim model, displace tJe sticks as
necessary to fly the model 'straigf,rt and level'
and press the auto-trim swltch. .ds you continue
to fly the airplane straight and level with the
auto-trlm button pushed, you will notice ttrat
eventually, the sticks will be in ttre neutral
position as the airplane flys tn the desired atti-
tude.
After the plane is rougfily trimmed by this
method, the best way to "fine tune" the AutoTftm
is to start with the control in neutral, push tlre
ALIO TRIM switch, and then *bump" ttre re-
spective control a few times ln the direction you
want to move the servo to get it ireto a trimmed
position. Youwillbesurprisedathowquickly
this unique method of trimming will become
second nature to you while flying.
The amount of offset from neutral the
AutoTrim feature has created can be read and
ttren incorporated as a new neutral, or you can
mechanically trim the airplane with tts linkage
and return to the transmltter's normal neutral
by zeroing out the AutoTfim. We wtll explatn
either procedure in the CAlibrate secflon of the
manual.
The speed at which the servos "slew" can be
controlled. Also, if d esired, the AutoTf im feature
can be turned off. See the section on Changing
the AutoTfim Slew Speed in the CAlibrate secl
tion.
Poge #6

E. Manual Trim
BesidesAutoTFim, your micropro is equipped
with normal, manual trims for the four primary
stick channels: Elevator, Aileron, Rudder, and
Throtfle. The sensitivity of the trim levers is
programmable in the Servo Calibration menu of
the CAlibrate mode from Oo/o to 5oolo of the
normal throw and there are two options on the
throttle trim which will be discussed later.
As it comes, your micropro is set up in the
"cross-trim" configuration: i.e., elevator and ai-
leron trims are on the left side of the transmitter
and controlled byyour left hand and the rudder
and throttle trims are on the right side of the
transmitter and controlled by your right hand.
This allows you to trim the airplane without
removing your hand from the control stick.
Ifyou want a different mechanical configura-
tion for your trims, it is a simple matter of
swapping connectors. Remove the back from the
transmitter, unplug the RF Deck and batteries,
and set the back aside. Look at the upper left
hand corrrer of the encoder PC board and ob-
serve the four connectors that are plugged into
the board; these connectors arewlred to the trim
levers. Note that the PC board is marked -ELV,
AIL, RUD, and THT." If you want to convert to
"standard trim," simply swap ttre ELV and THT
connectors and the AIL and RUD connectors.
When ptugging them back in, make sure you
maintain ttre proper polarity: i.e., the red rvire
should always be on the left. There ls another
check for proper polarity. Look on the bottom of
the connector and observe the '1" stamped into
the plastic. When it is plugged in, the * 1" should
correspond wift the pin that is marked with a
small vertical line printed on the PC board.
Now reinstall the back, MAKING SURE you
plug BOTH connectors into the RF deck and the
battery pack is plugged in.
NOTE: ifyou have swapped the trims around,
you must perform the Set Joysticks routine.
(Section VII.)
F. Voltmeter
The LCD Display normally shows the voltage
of the micropro's eigfrt cell ni-cd battery pack,
depending on the state of charge ofthebatteries.
Normal operating voltage will be over I lV when
thebatteries are freshly charged and 9.6Vis tl.e
minimum operating voltage. When the voltme-
ter goes below 9.6V, the batteries are becoming
discharged, and a new pack needs to be installed
or the existing pack needs to be recharged.
When the batteries reach 9.6V, the voltmeter
display starts to blink andwhen thevoltage goes
down to a dangerous level, (9.4V) the audio
alarm sounds continuously to warn you to stop
operation immediately.
G. Battery Timer
You also have a Battery Timer that will tell
you how many minutes the transmitter has been
on since the last time the batterles were charged.
It is not automatic and has to be reset in the
Special Functions menu of the CAlibrate mode
whenyou rechargethebatteries in orderto do its
Job. Instructions will follow.
To display the Battery Timer, push the
AutoTrim button when the transmitter is in ttre
RIIN mode and all the stlcks are at rest ln
neutral. Now the display will show the Battery
Timer instead of the Voltmeter. It is shown in
minutes from OOO to 999. To return to the
Voltmeter mode, push the Auto-him button
again and the Voltmeter will be displayed.
H. Flight Timer
The micropro has a "count-up' or a'count-
down" flight timer which is displayed on the
LCD. You determine which conliguratlon in the
Special Functions menu of the CAlibrate mode.
To activate the flight timer in the RUN mode,
click the Option Switch once to start the clock,
again to stop the clock (display wiU blink), and
again to clear the clock.
In the "count-down" mode, theAudio Alarm
will alert you as you reach zero as follows: at one
minute, it will beep three times: at 3O seconds,
itwill beep twice; at 1O seconds, itwill beep once:
and, at 5 seconds, it w'ill beep each second until
it reaches zero.
l. Throttle Preset
When pushed and held, the throttle preset
button will move the throttle servo to a pre-
programmed setting. This feature is designed
primarilyto ldll tle engine upon command. Or,
it can take the throttle channel servo to any
setting desired for whatever purpose: for ex-
ample, it maybe a preset flap or spoiler position
for $iders. It is programmed in the CAlibrate
mode.
Poge #7

J. Setting Engine ldle in the RUN
Mode
A handy feature of the micropro is that you
can set the LO throttle endpoint while in the RUN
mode. With this feature, you can have the engine
running and easily set the engine's idle RPM
without having to go into the CALibrate mode.
To do so, while in the RUN mode, push and hold
the AutoTrlm button first and then the Throttle
Preset button, in that order. While still holding
both buttons down, 'slew" the throtfle servo
higher or lower using the elevator stlck. (Refer to
the CAL instructlons to deflne the "slewing'
technique; it will become automatlc as you learn
to use the micropro.) CAUTION: this process
must be done while the plane is on the ground
and while someone is holding the airplane be-
cause all the other functions are deactivated
while using this feature. Be sure to depress the
switches i:r the proper order: Iirst ttre AutoTflm
and then ttre Throttle Preset button; when you
release them, the transmttter will return to the
normal run mode with only the throttle servo LO
endpoint being affected, nothing else.
To summarize:
1. Push and hold AUTO TRIM.
2. Then push and hold PRESET.
3. Slew throttle servo with ELEVATOR
STICK.
4. Release both buttons, keeping the
throttle stick at idle.
K. Throttle Trim Options
In the Special Functions menu of the GAL
mode, you can determine which of two options
are turned on for the throttle trim function; they
are elther:
l. The'T" (throtfle trtm) option, which causes
the throttle trim lever to be effectlve only while
the ttrottle stick is in the LO throttle position.
That way, the HI throttle endpoint settlng stays
the same, no matter what the throttle trlm lever
position is.
2. Or, the *N" (normal trim) mode, whtch
allows the throttle trim lever to be effective
throughout the entire throttle stick movement.
L. Eight Aircraft Memory
The micropro 8OO0 has ttre conslderable
ability to program eight different aircraft: AIl of
the flight parameters for a particular airplane
are stored away in memory, and are recalled by
the SELECTAIRCRAFT# menu in the CAlibrate
mode. When in the RUN mode, the aircraft
Poge #8
number selected is displayed on the LCD.
M. The Audio Alarm
The micropro 8OO0 is equipped with an audio
alarm which "beeps" when certain things hap-
pen.
One, when you switch from the RIIN mode into
the CALibrate mode, the alarm will beep three
times to tell you that you are gotng lnto a
different mode. Also, if the transmltter is in the
GAlibrate modewhenyou turn it on, itwill beep
three times to warn you that you are not in the
proper mode to fly with the transmitter.
TWo, whenthebatteries reach a dangerously
low voltage level (9.4V), the alarm emlts a con-
stant beep and operation should be ceased as
soon as possible.
Three, in the countdown mode, the Audio
Alarm gives an alert of when the countdown is
reaching the end. It will beep three times when
the timer reaches one minute, turice at 3O sec-
onds, once at lO seconds and once every second
from 5 seconds to zero.
IV. THE CALIBRATE MODE
All the programming is done ln the CALibrate
mode. You enterthe CAlibrate modebymoving
the RIIN/CAL switch to CAL. As a safety mea-
sure, you will have to ltft the swttch lever to get it
to move. Whenyou go into the CAlmodewtth the
transmitter on, the Audio Alarm will beep three
times. If you are alreadytn tl e CALmodewhen
you turn the transmitter on, the alarm will also
beep three times.
A menu system will verbally guide you through
the calibratlon procedure by displaylng your
actions on the LCD, making the setup easy.
You wlll be learnlng three basic moves which
wlll be almost all you need to know to unleash the
power of your micropro:
-Topagethrough the menu leftand right, you
move ttre aileron stick left and right.
A
I
-T
++L
-To move deeper into or out of the
structure, you click the option button.

'GL[CK'
-To increase or decrease ttre calibration val-
ues, you move the elevator stick up or down.
Another aid to calibration of the micropro is
the Flow Chart. This Flow Chart is your road map
to the micropro system. It guides you to a par-
ticular point in the CAlibrate mode where you
might want to go; or, it will tell you how to get out
of a particular spot if you are lost. Once you gain
famitiarity with the system, you will ffnd that if
you need to refer to the instmctions at all, you
will only need to look at the Flow Chart.
In the process of set-up, you can have the
receiver in the airplane turned on and actually
watch the servos react to your inputs. Thatway,
you can correlate actual servo motion to what
you will see displayed.
Another feature of this transmitter that is a
help in set-up, is the ability to, upon command,
move all ttre servos to their center of travel, no
matter what. That simplifles things when you are
mechanically setting up a given airplane.
A. Glossary of Terms:
ABSOLUTE MDilNG: Available only when the
"FROM" mixing channel is a neutralizing chan-
nel. It causes the'TO" channel to be affected in
the same direction by the "FROM" channel, no
matter which way the *FROM" channel stick is
deflected from neutral.
DIGITAL PULSE METER (DPM): The display of
the actual pulse width being transmitted to the
receiver measured in milliseconds. The width of
the pulse determines servo posiUon. Normal
operation is 1.5O ms neutral I O.O5 ms. The
micropro will not transmit beyond O.8O and 2. 1O
ms.
"FROM" CFIANNEL: The channel that provides
the input from which mixing occurs. Also known
as the "master" channel.
PAGE RIGHT OR LEFT: Move the aileron stick off
neutral to the right or left and return to neutral.
This will change the menu page displayed to the
tr
ELV
next page either right or left.
SLEU/UP ORDOWN: Move the elevator stick off
neutral upwards or downward and hold. The
number being displayed will increase or decrease
until the stick is returned to neutral.
SLEWING SERVOS: When the computer "slews"
a servo, it moves in a smooth, slow manner that
prwents abrupt adjustments.
'TO" CFIANNEL: The channel that gets mixed to
by the stick input of the "FROM" channel. Also
known as the "slave" channel.
TOGGLE RIGFII OR LEFT: Move the aileron or
the rudder stlck off neutral either right or left and
return to neutral. This will cause a particular
item on the display to change to the next item.
TOGGLE UP ORDOWN: Move the elevator stick
offneutral eitherupward or downward and return
to neutral. This will cause a particular item on
the display to change to ttre next item.
ZERO MIX POINT: The "FROM' channel's posi-
tion when no mixing occurs. It is in neutral on
the three neutralizing channels. On the non-
neutralizing channels, it can be set for either the
upward, downward, or middle position of the
switch or lever. It is selected by pushing the
AI-[O TRIM button in the SET MDilNG VALUE
menu.
B. Selecting the Aircraft
We use ttris procedure to select the aircraft
(# I through #8) for the purposes of flying it in the
RUN mode or setting it up in the CAlibrate mode.
It will serve as your first exercise in using the
micropro's powerful features; refer to the FIow
Chart as you progress.
Begin by turning the transmitter on and
switch into the CALmode. The followingwill be
displayed:
$ELEII HIFCHHFT S
You are at kvel One in the menu structure
and on Page One.
Now, using ttre aileron stick, "Page Right"
ttrrough this level of the menu. To do this, simply
move the aileron stick to the right and return to
neutral. Note that the displayhas changed to the
next page in the menu. Repeat again and again
Poge #9

until you come back to SELECT AIRCRAFT#.
Nowf6r exercise, "Page Left" throu$h this level of
the menu. To do thls, move ttre aileron stick to
ttre left and return to neutral. Repeat until you
return to SELECT AIRCRAFT#. Visualize this
level of the menu as a continuous loop that you
can move right or left in by using the aileron s tick.
You have just learned one of the basics of
micropro operationt
Now, learn the second basic by clicking the
OPTION button while the display reads SELECT
AIRCRAFT# whichwill moveyou deeper into the
menu structure which we call Level TWo.
The display reads:
HIHIHHFT l'l|Jll = I
C. Calibrating the Servos
1. Setting Neutrals, Normal and Dual
Rate Endpoints, and Trim 7o
The second page in Level One of the menu
structure lets you set up ttre servos for each ofthe
transmitter's eight channels. Ttre parameters
are: both endpoints of servo travel (including the
dual rate switch settings): the neutral position:
and, the sensitivity of the manual trim lever for
the four stick channels. What is traditionally
known as "servo reversing" is performed when
you set endpoints. We rvill cover each one in
detail.
Go into the CAL mode and SELECT AIR-
CRAFT # appears. Page Rigltt to:
IHL I EHHTE 5ERUO5
Click the OPTION button to move to Ievel Tlvo
and the following wtll appear:
ELEUHTOH
Now, with the aileron stick, Page Right and
Left through LwelTWo of the CALIBRATE SERVO
menu page to familiarize yourself with this tevel.
Note that we cover all eight channels, plus a
"SAVE NEW VALUES', an "EXIT TFIIS MENU",
and an'INITIALIZE SERVO" function. We will
cover each of these tn detail.
Note: If you want to odt this level of the menu
for any reason, you c€ul do so two ways. One,
page to the E)flTTHIS MENU function and click
the option button; you will move back up to Level
One of the menu. The other way is to simply
switch the RUN/CAL switch back to RIIN.
Return to:
You will now learn the third basic of calibration
which is to "Slew' the displayed value up or
down. To do this, move the elevator stick upward
from neutral and hold. Watch the AIRCRAFT
NUM increase in value up to 8 and then loop
around to I and continue to increase. Release
the sttck to neutral and note that the number
stays the same. Now move the stick downward
and hold, watching the number decrease in
value. It too, continues to loop around until you
neutralize the stick.
With the desired aircraft number displayed,
click the OPTION button to move back upward in
the menu stmcture to Level One and watch the
display read once again:
SELECT HIHIHHFT S
InJust a few minutes, you have just learned
almost alt you need to know about the calibration
procedure for your micropro! Easy, wasnt it?
The same basic moves will serve you throughout
the micropro experience.
In orderto retum to the RUNmode, slmply
swttch back to the RUN mode whlle ln Itvel
One of the menu structure and you are ready
for operatlon.
