Using the Manual
It is NOT recommended that you read it cover to cover unless you have trouble falling asleep at night.
However, the manual will be a fine resource on the methods and programming details of the Aurora.
As you use the radio, use this manual!
The Aurora manual is divided into seven distinct sections;
1. Introductory material that is mandatory reading. This is where you will learn detailed
information that will be invaluable to successful Aurora programming.
2. Airplane/Glider quick start guide.
3. Heli quick start guide.
4. System menu programming common to all ACRO, GLID and HELI models.
5. Model menu programming common to ACRO, GLID and HELI models.
Additional menus and switch selection process
6. Model menu programming for ACRO and GLID models.
7. Model menu programming specific to HELI models.
Warning, Caution, Note and Tip Boxes
Throughout the manual you will see important information inside a labeled box. Take care to note this information.
Here’s a sample;
Quick Set-up Guides
We recommend that you read the introductory information in section one, then jump right into one of the quick start
guides and start programming. After following along with the quick start guide you will have a “feel” for the way the
Aurora’s programming architecture has been laid out. We encourage you to set-up a few aircraft before you fly the Aurora.
It will be time well spent and help smooth your passage along the programming learning curve.
Aurora Software Architecture Explained.
Unlike prior Hitec radios, the Aurora features “open” software architecture. Any function can be controlled by almost any
switch, slider, gimbal stick or button. To ease your way through the programming, many of the traditional channel choices
and control functions are used by default, until you get to the more sophisticated set-ups. By the time you graduate to
programming complicated models, you’ll be well schooled in programming your Aurora.
As you add more functional choices to a models programming, you may be called upon to tell the Aurora what switch
you would like to use for activating functions like retracts, gyros, dual and exponential rates, flight conditions and mixing
functions.
The Aurora is a powerful computer. Anyone who has used a computer will acknowledge the only way to really become
proficient with any software program is to use it. We at Hitec encourage you to invest several hours in setting-up various
airframes before you ever use the Aurora.
Take the time to familiarize yourself with the programming architecture. The flow of the programming will literally pull
you through the set-up process. You will find with a little practice, that within a short time you will master the Aurora’s
capabilities.
Steps for Aurora Programming Success
Many of you have owned or used earlier model Hitec transmitters. Here are seven “new” Hitec transmitter
features that set the Aurora apart from all other Hitec products.
1. Signal Protocol
Your Aurora can transmit three different signals, 72MHz FM, QPCM and 2.4GHz.
1. Using Hitecs AFHSS 2.4GHz module to link with Hitec Optima AFHSS 2.4GHz receivers.
2. Use the SPECTRA PRO, 72MHz frequency synthesizer module to fly any brand of 72MHz receiver, on any channel.
3. Select the Hitec QPCM signal option when using the SPECTRA PRO module to use the QPCM receiver on any channel.
2. Touch Screen Programming
Look at me, no buttons! Just press the icon or word on the screen to easily flow through the Aurora programming.
3. 72MHz Synthesizer
Use the new SPECTRA PRO module in your Aurora and select any of the fifty 72MHz channels through the Aurora software.
No more taking the module in and out of the radio to change your frequency.
4. Battery Management
The Aurora arrives with a six cell NiMH battery and 110V or 220V charger. It does have the option of using a six cell NiCd,
NiMH pack, or a 2 cell Li-Po battery. Using a Li-Po entails removing the battery from the transmitter for charging with an
appropriate charger.
5. Gimbals
Feel the silky smooth action of the new four ball bearing supported gimbals in the Aurora 9. These new gimbals were
created to give you the smoothest action demanded by the highest performance aircraft.
6. Switch Assignments
During the model programming steps you will be asked to select what stick, switch or slider controls the features you want
to use with your model. This gives you unlimited flexibility to choose the most comfortable and practical way for you to use
the Aurora.
7. Channel and Control Assignments
The Aurora will automatically select the channel and control assignments based on the model you have. There is the option
to change them if you wish, allowing you a wider choice of receivers that can be used with the Aurora.

Flying models can be dangerous if proper safety precautions are not followed. Here are a few critical safety
suggestions to keep you and others safe.
Are you experienced?
Flying models is not an intuitive process. Most accomplished model pilots were taught by another modeler. We encourage
you to seek help during your early flight experiences and if required, during the building and gear installation process. Unlike
some other hobbies, model airplane flying has evolved into a social event. There are approximately 2,500 model aircraft clubs
in America. Friendship and help could be right around the corner. Ask your local hobby shop about clubs in your area.
Where to Fly
Having enough land for your own model airport is rare. Most of us fly at club administrated model fields. The local ball field
can be tempting but rarely has the space needed and your liability is high should you damage property or hurt an innocent
person. We recommend you fly at a sanctioned model aircraft field.
Join the AMA
In America, the Academy of Model Aeronautics (AMA) is an organization of model enthusiasts that provide resources and
insurance to modelers. The AMA also lobbies the Government concerning legislation that impact modelers.

Fundamental Guidelines for Safe Flying
1. Don’t fly over people or personal property.
2. Make sure you do a range and pre-flight check on your aircraft.
3. Check for others flying on your frequency. (No need with 2.4GHz)
4. Know your batteries condition. Keep them charged.
5. The equipment we use in the R/C hobby is sensitive electronic gear. Have receivers checked after a crash before using
them in another aircraft.
6. Use the Fail-Safe function in AFHSS and QPCM mode to lower the throttle in case of a signal “lock-out”.
7. Don’t fly alone.

Transmitter Battery InformationAurora Transmitter Warnings
In flight warnings
Lower the throttle to proceed.
Turn the mixes off to proceed.
Your Aurora transmitter is supplied with a rechargeable, 6 cell, AA size, 2000mAh Nickel Metal Hydride(NiMH)
Eneloop battery pack with a nominal voltage of 7.2V.
Charging
The preferred charging method is to use the supplied CG-S45 overnight wall charger. Plug it into the port as shown in the
diagram. Note the red “charging in process light” on the CG-S45 overnight wall charger. This light will turn green when
charging is complete. Normal procedure is to charge overnight before flying the next day.
Do not install a Li-Po in the Aurora and then try and charge it with the supplied CG-XX overnight wall charger.
The CG-XX was created for NiMH cells only! Certain major damage is sure to occur.
Caution
The battery can be removed from the radio and charged with a “quick” charger.
The recommended charge rate should be no more than 2 Amps.
Power Meter
There are two ways to review the battery voltage on the Aurora home screen. A “direct voltage read out”, and a “percentage
of available power” graph can be displayed by touching the power icon on the main menu.
The Li-Po Option
The nominal voltage of a two cell Li-Po or Lithium Polymer battery pack is 7.4V. The user has the option to power the Aurora with a 2S
Li-Po but accepts full responsibility to do so safely. To use a Li-Po transmitter battery safely, you must remove the battery from the
transmitter case for charging, and reinstall it after charging.

Solid red and blue LEDs indicator that the receiver is linked with the module.
c. Turn off receiver.
d. Turn off transmitter.
e. Turn on transmitter, red LED is solid, blue LED is blinking.
f. Turn on receiver, red LED is solid, after a moment, the blue LED will also come on, and the module emits one long beep.
g. You should now have control over the model as the transmitter and receiver are bound in Scan Mode.
Each system and module / receiver set is paired at the factory for your convenience. Use the following Linking (ID-Setting)
sequence as you add Optima receivers into other aircraft to be controlled by your Aurora.
Note
- Binding must be done within 15ft. (5m) of the transmitter and receiver.
- Transmitter and receiver need to be at least 18in. (45cm) from each other to binding properly.
- In the ScanMode, if the transmitter or receiver has been shut off or disconnected for more than one second,
both module and receiver need to re-boot (turn the power off, and back on).
Note
To turn the system on and off, use the following sequence at all times
Turning On -Turn on the transmitter, select “transmit”, then turn on the receiver.
Turning Off -Turn off the receiver, then turn off the transmitter.
Warning
Always do a pre-flight function check
Before the engine or motor is started, turn on the system as explained above. Then make sure all the servos and control surfaces are
working properly. If any control surface is not moving properly, do not fly the aircraft until the problem is solved.
Range Check
Do a complete range check as described on page 20 before each flying session to confirm the radio system is working properly.
Your Hitec AFHSS system uses a communication protocol that links and binds the Optima receiver to your Aurora transmitter. Once their
ID is set, no other transmitter can interfere with your receiver during its operation. In the case of multiple model memory transmitters like
the Aurora, you can bind or link as many Optima receivers to your transmitter as necessary.
Normal Mode
- In this mode the receiver/transmitter uses the frequencies which selected at the time it was initially set-up.
- After the initial set-up, the everyday start-up is quicker in the Normal Mode. In 90% of cases the Normal Mode is preferred by users.
- In the Normal mode, if the transmitter or receiver loses power, then power is restored, the system will re-link and function normally.
- The factory default setup is Normal Mode.
Scan Mode
- In ScanMode the receiver/transmitter will scan all available channels every time you turn it on. It will then choose the cleanest
frequencies to use. ScanMode is preferable to use when flying in a crowded 2.4GHz environment.
- While in ScanMode if the transmitter loses power it will not rebind to the receiver, if the receiver loses power it will take longer
to re-bind than when in Normal Mode.
- In all cases the ScanMode binding function will take longer than in Normal Mode when you boot-up the system.
Changing from Normal Mode to Scan Mode
a. Turn on transmitter, then the receiver.
b. After linking and you have control over the model, press the button on the module for 6 seconds, you will hear one beep
followed by two beeps then release the button.
c. The module will now switch to ScanMode noted by the red and blue LED and one beep.
d. Turn off the transmitter and receiver.
e. Turn the system back on and wait for the system to boot and you have control over the model in ScanMode.

Set-up and Use of the Hitec 2.4GHz System
Scan Mode and Normal Mode Selection
Hitecs Spectra 2.4GHz module and Optima series receivers have two different operational modes to choose from,
“Normal” or ScanMode.
There are available 2.4GHz channels that can be used by your Hitec AFHSS 2.4 system. The following will explain
how Normal Mode and ScanMode use the channels.
FAIL-SAFE and Hold Mode
If you use the FAIL-SAFE function, and set it up properly, should the receiver signal somehow be interrupted or
interference were to occur, the servos will move to your pre-set FAIL-SAFE point you previously stored in the
receiver during the FAIL-SAFE set-up process.
If FAIL-SAFE has not been activated, the signal is switched off after the HOLD period of 1 sec. This means that the
servos become “soft” and remain in their last commanded position under no load (this may equate to full-throttle!),
until a valid signal is picked up again.
In the interests of safety, we recommend that FAIL-SAFE should always be activated, and the FAIL-SAFE settings
should be selected so as to bring the model to a non-critical situation (e.g. motor idle / electric motor OFF,
control surfaces neutral, airbrakes extended, aero-tow release open, etc).

Telemetry System
Currently there are two direct feedback telemetry functions available in your Hitec 2.4 system. Plans are to have many more
devices available in the future. Check the Hitec web site at www.hitecrcd.com for more up-to-date information.
I. Low Battery Warning
The 2.4 system will automatically recognize the receiver battery voltage among 4 and 5 cell NiMH or Nicad packs and 2S Li-Po/Io/Fe
batteries packs.
- When battery level is high (4 cell > 4.5V, 5 cell > 5.6V): The red module LED glows constantly.
- When battery level is low (4 cell < 4.5V, 5 cell < 5.6 V): blue LED glows constantly and the red LED will blink fast.
You will hear a continuous loud beep from the module as a low receiver battery warning. Upon hearing the alarm, we advise you to
land at once.
SPC (Supplementary Power Connection) System
Hitecs exclusive optional receiver power system allows you to directly power the receiver from the main motor power battery of
an electric powered aircraft. Up to 35 Volts can be fed directly into the receiver to power JUST THE RECEIVER FUNCTION. It will not
power the servos. Almost all servos will burn-up if more than 6 Volts are used over a short period of time.
Note; some Hitec servos are rated to be used at 7.4Volts. You will still need to supply power for your servos with a four or
five cell NiMH receiver battery, 2 cell Li-Po and regulator set-up, or a commercially available BEC. The SPC system was partially
created to be integrated into future Hitec telemetry system devices. Check the Hitec web site for more information on the availability
of telemetry systems in the future.

Set-up and Use of the Hitec 2.4GHz System
FAIL-SAFE Setup
a. Switch on the transmitter, then the receiver, wait for the system to boot and you have control over the model.
b. Press and hold the receiver function button for 6 seconds, release the button. After 2 more seconds both red and blue
LEDs blink rapidly.
c. From the moment you release the button, the receiver will count 5 seconds during that time move all the transmitter sticks
and other controls to the desired FAIL-SAFE positions (e.g. motor idle, control surfaces neutral), and hold them there.
d. After 5 seconds the system will save the FAIL-SAFE position. Relax all the control sticks.
e. Turn off the receiver, then the transmitter.
f. Turn on the system to use it. FAIL-SAFE is now activated.
Testing the FAIL-SAFE Setting
a. Move the sticks to positions other than the FAIL-SAFE settings, and then switch off the transmitter. The servos should now
move to the FAIL-SAFE positions previously stored, after the HOLD period (1 sec.) has elapsed.
How to turn FAIL-SAFE Off and reactivate the Hold Mode
a. Switch on the transmitter, then the receiver. Wait for the system to boot and you have control over the model.
b. Press and hold the receiver function button for 6 seconds and release it. After 2 seconds the red and blue LEDs will blink rapidly.
c. Immediately press the button and release it.
d. FAIL-SAFE Mode is now deactivated and HOLD mode is activated.
e. Turn the transmitter off, then the receiver off.
f. Turn the system back on to use it.
Range Check Function
It is critical that before each flight session you perform a range check that confirms the signal between the receiver and transmitter is
appropriate. Unlike the FM/PPM or PCM signal radios, 2.4GHz systems use a fixed shorter, stubby transmitter antenna so the traditional
method of range checking your system by lowering the transmitter antenna will not work.
We instead use a power-down mode to reduce the transmitter signal strength. Once the power-down mode is activated it runs for about
90 seconds, shortening the effective range 100 feet (30 m). During this power-down mode that you should walk away from the secured
aircraft carrying the transmitter to a distance of approx. 30 meters, testing the effective range.
How to use Power-Down
a. Press the button on the module for 3 seconds, then both the blue and red LEDs will turn on with single beep sound. Release the
button. The 90-second countdown starts from the time the button released.
b. Walk away from the secured aircraft carrying the transmitter to a distance of approx. 100 feet (30 m), testing the effective range.
c. To exit the power-down mode before the 90 seconds, press the button again to escape.
Set-up and Use of the Hitec 2.4GHz System
- If FAIL-SAFE is deactivated, the FAIL-SAFE position settings are also deleted!
- The FAIL-SAFE settings should be checked every time before you run the engine/motor.
Warning
If you are unable to accomplish a successful range check of 90 feet, DO NOT ATTEMPT TO FLY.
