Spektrum SPMAR9300 User Manual

Feeder Antennas

The AR9300 incorporates feeder antennas, which are designed to be easily mounted through the fuselage in carbon airplanes. The main receiver has two 8-inch feeder antennas and the remote receiver has one. Each feeder antenna includes a coaxial portion (which can be thought of as an extension) and an exposed 31mm tip antenna. The last 31mm is the active portion of the antenna.

Step 1. Identifying the Types of Carbon Aircraft

While some sailplanes are full carbon construction, most only use carbon in areas that require extra strength. Many of the latest sailplanes are constructed with 2.4GHz-friendly fuselages meaning that the forward section of the fuselage is constructed from non-conductive materials like ﬁberglass and Kevlar that don’t affect the RF signal. The ﬁrst step in a proper installation is identifying the type of aircraft which will fall into one of three categories below.

A. Full Carbon

All components of the airplane including the entire fuselage, the wing and tail are constructed of carbon ﬁber or have a carbon ﬁber weave throughout the aircraft.

This type of aircraft will require that all antennas be installed externally.

B. 2.4GHz Friendly Fuselage with Carbon Wing

The section forward of the wing is constructed of nonconductive materials like ﬁberglass, Kevlar, etc. but the wing and possibly the tail section have carbon or carbon weave construction.

Antennas in the nose of this type of aircraft can be installed internally while an antenna installed behind the wing must be mounted externally.

C. 2.4GHz Friendly Fuselage with Molded Non-Carbon Wing

The section forward of the wing and the wing itself is constructed of non-conductive materials like ﬁberglass, Kevlar, etc. The wing may, however, contain a carbon spar, which is an insigniﬁcant volume of carbon to have an effect. The tail section can be either carbon, carbon weave or ﬁberglass construction.

All antenna can be mounted internally forward of the wing in this type of aircraft.

Step 2. Determining Antenna Mounting Positions

After determining the type of aircraft from the list above, use the above illustrations as a guideline as to where the feeder antennas should be mounted. The goal is to mount the antennas in a location such that at least two will always be in the RF visual line of sight of the transmitter (i.e. not blocked by carbon ﬁber structures) in all attitudes. This can easily be visualized by having a helper stand about 20 feet away and rotate the airplane in all attitudes conﬁrming that in all positions there is a direct line between you and at least two receiver antennas that aren’t blocked by carbon ﬁber structure.

Note: If you have a full carbon sailplane, it is highly recommended that an optional fourth receiver with feeder antenna be installed. Carbon Fuselage Remote (SPM9546)

AR9300 User Guide

Spektrum’s AR9300 9-channel receiver is designed for carbon fiber aircraft installations.

Receiver Installation in Aircraft

Airplanes with signiﬁcant carbon ﬁber construction can create an RF shielding effect, reducing range. The AR9300 is designed to overcome these critical RF issues in carbon airplanes by outﬁtting the aircraft with external antennas when necessary at speciﬁc points that will ensure secure RF coverage.

Step 3. Installing the Receivers

Install the Main receiver in the normal position recommended by the airplanes’ manufacturer, noting that the data/bind port should be easily accessible as a ﬂight log will be used to conﬁrm RF link performance. Double-sided tape or foam can be used to secure the main receiver in place. Using double-sided servo tape mount the remote receiver(s) within 3 inches from where you intend on having the antennas exit the fuselage.

Step 4. Mounting the Antennas

Three 2.4GHz Antenna Exit Guides (SPM6824) antenna mounts (with tubes) are included to make external mounting easy. To install the antenna mount, drill a 1/8-inch hole in the desired antenna mounting position; then, using a hobby knife slot the hole as shown.

Insert the tube in the mount; then using medium CA, glue the mount and tube in place in the fuselage. Trim the tube to length inside the fuselage if necessary. Now slide the feeder antenna through the tube until the 31mm tip completely exits the mount. Using a drop of CA, glue the antenna to the mount making sure that the 31mm active portion of the antenna tip is fully exposed.

Note: If the antenna is to be mounted internally (in the front of a 2.4GHz friendly fuselage) the coax can be taped into position. Be sure the 31mm tip is located at least 2 inches from any signiﬁcant carbon structure and from the battery.

Step 5. Plugging in the Servo Leads

Plug the servo leads into the appropriate servo ports in the receiver noting the polarity of the servo connector. Note that the signal wire (orange for JR servos) faces toward the center of the receiver. Consult your radio’s manual for speciﬁc detail as to which servo plugs connect into which servo port channel.

Step 6. Binding the Receiver

Binding

The AR9300 must be bound to the transmitter before it will operate. Binding is the process of teaching the receiver the speciﬁc code of the transmitter so it will only connect to that speciﬁc transmitter.

1. To bind an AR9300 to a DSM2 transmitter, insert the bind plug in the BATT/BIND port on the receiver.

2. Power the receiver. Note that the LED on the receiver should be ﬂashing, indicating that the receiver

is in bind mode and ready to be bound to the transmitter.

3. Move the sticks and switches on the transmitter to the desired failsafe positions (normally mid ﬂap for dethermalizing).

4. Follow the procedures of your speciﬁc transmitter to enter Bind Mode, the system will connect within a few seconds. Once connected, the LED on the receiver will go solid indicating the system is connected.

5. Remove the bind plug from the BATT/BIND port on the receiver before you power off the transmitter and store it in a convenient place.

IMPORTANT: Remove the bind plug to prevent the system from entering bind mode the next time the power is turned on.

Step 7. Radio Setup and Programming

Following the instructions in your radio manual, program your airplane.

Step 8. Rebinding the Receiver

After you’ve programmed your model, it’s important to rebind the system so the true failsafe control surface positions are set.

Step 9. Ground Range Testing and Verification with Flight Log

Advanced Range Testing Using a Flight Log

In airplanes that have signiﬁcant carbon ﬁber construction it is imperative to ﬁrst do a ground range check using a ﬂight log. This ground range check will conﬁrm that the internal and remote receivers

are operating optimally and that the antennas are properly mounted in a position that will give positive RF coverage in all attitudes. This Advanced Range Check allows the RF performance of each receiver and the positions of each antenna to be veriﬁed and to optimize the locations of the antennas.

Advanced Range Test

1. Plug a Flight Log (SPM9540) into the data port in the AR9300. If the port is being used for the battery, a Y-harness can be used or plug the battery into any other unused port.

2. Turn on the system (Tx and Rx).

3. Advance the Flight Log until F- frame losses are displayed by pressing the button on the Flight Log.

3. Have a helper hold your aircraft while observing the Flight Log data.

4. Standing 30 paces away from the model, face the model with the transmitter in your normal ﬂying position and put your transmitter into range test mode. This causes reduced power output from the transmitter.

5. Have your helper position the model covering all orientations (nose up, nose down, nose toward the Tx, nose away from the Tx, etc.) while your helper watches the Flight Log noting any correlation between the aircraft’s orientation and frame losses. Do this for one minute. The timer on the transmitter can be used here.

6. After one minute release the range test button and read the data from the Flight Log. A successful installation will yield the following:

0 - holds, less than 20 Frame Losses

It’s common to see high values on individual receivers as the carbon structure can block the signal in various orientations. What is important is that at least two receivers are receiving well at all times. If more than 20 frame losses or any holds occur redo the test noting the aircraft orientation when the fades and holds occur. This will allow you to change and optimize the antenna position(s) to a better location.

Step 10. Short Test Flight Verication with Flight Log

When the system tests successfully as directed above, it’s time for a short near test flight. This first flight should be close (less than 500 ft and about five minutes). After the flight, land your aircraft nearby (less than 60 ft away)* and check the Flight Log data. Again a successful flight will result in 0 holds and less than 20 Frame losses. Extend the flight distance and times checking the Flight Log data after every flight until you are confident with the results. Many pilots choose to mount the Flight Log in the airplane making data checking convenient. *If the sailplane is landed more than 60 feet from the transmitter the system may experience higher than normal frame losses and holds. This is because the antennas are within inches of the ground and the signal can be blocked by the ground causing RF link degradation. Note that when landing more than 60 feet from yourself, high flight log values are normal.

Important: Y-Harnesses and Servo Extensions

When using a Y-harness or servo extensions in your installation, it’s important to use standard nonampliﬁed Y-harnesses and servo extensions as this can/will cause the servos to operate erratically or not function at all. Ampliﬁed Y-harnesses were developed several years ago to boost the signal for some older PCM systems and should not be used with Spektrum equipment. Note that when converting an existing model to Spektrum be certain that all ampliﬁed Y-harnesses and/or servo extensions are replaced with conventional non-ampliﬁed versions.

Preset Failsafe

The AR9300 features Preset failsafe only. Preset Failsafe is ideal for sailplanes, allowing the aircraft to automatically dethermalize if signal is lost. With Preset Failsafe, when signal is lost all channels go to their preset failsafe positions (normally mid ﬂap) preventing a ﬂyaway.

• Prevents yaways should the signal be lost

• Eliminates the possibility of over-driving servos

Receiver Power Only

• When the receiver only is turned on (no transmitter signal is present), all channels have no output

signal, to avoid overdriving the servos and linkages.

Note: Some analog servos may drift slightly during power-up even though no signal is present. This is normal.

Shown using a separate receiver pack. (Battery can be plugged into any open port.)

When binding through an ESC, the ESC’s lead must be plugged into the port operating the motor, typically the gear or AUX2 channel. The servo monitor is helpful in determining which channel is being used.

Flight Log (SPM9540 Optional)

The Flight Log is compatible with the AR9300. The Flight Log displays overall RF link performance as well as the individual internal and external receiver link data. Additionally it displays receiver voltage.

Using the Flight Log

After a ﬂight and before turning off the receiver or transmitter, plug the Flight Log into the Data port on the AR9300. The screen will automatically display voltage e.g. 6v2= 6.2 volts.

Note:

When the voltage reaches 4.8 volts or less, the screen will ﬂash indicating low voltage.

Press the button to display the following information: A – Antenna fades on internal antenna A B – Antenna fades on internal antenna B L – Antenna fades on the left external antenna R – Antenna fades on the right external antenna F – Frame loss H – Holds

Note:

– – – (three dashed lines) will appear if the antenna is not attached

Antenna fades—represents the loss of a bit of information on that speciﬁc antenna. In a carbon aircraft it’s not uncommon to have antenna fades maxed out. This is due to the fact that individual antennas may be blocked at times during ﬂight by carbon structure. What’s important is that at least two antennas are receiving good information at all times.

Frame loss—represents simultaneous antenna fades on all attached receivers. If the RF link is performing optimally, frame losses per ﬂight should be less than 20 in a ﬁve minute ﬂight. A hold occurs when 45 consecutive frame losses occur. This takes about one second. If a hold occurs during a ﬂight, it’s important to evaluate the system, moving the antennas to different locations and/or checking to be sure the transmitter and receivers are all working correctly.

Note: The Flight Log can be plugged in, attached and left in the model using double-sided tape.

Mounting the Flight Log conveniently inside the fusalage is recommended.

Tips on Using Spektrum 2.4GHz

ModelMatch™

Some Spektrum and JR transmitters offer a patent pending feature called ModelMatch. ModelMatch prevents the possibility of operating a model using the wrong model memory, potentially preventing a crash. With ModelMatch each model memory has its own unique code (GUID) and during the binding process the code is programmed into the receiver. Later, when the system is turned on, the receiver will only connect to the transmitter if the corresponding model memory is programmed on screen.

Note: If at any time you turn on the system and it fails to connect, check to be sure the correct model

memory is selected in the transmitter. Please note that the Spektrum Aircraft Modules do not have ModelMatch.

While your DSM equipped 2.4GHz system is intuitive to operate, functioning nearly identically to 72MHz systems, following are a few common questions from customers.

1. Q: Which do I turn on rst, the transmitter or the receiver? A: If the receiver is turned on ﬁrst —no servo outputs are present so all servos remain in their position

and if an Electronic Speed Control is being used, it won’t arm. When the transmitter is then turned on the transmitter scans the 2.4GHz band and acquires two open channels. Then the receiver that was previously bound to the transmitter scans the band and ﬁnds the GUID (Globally Unique Identiﬁer code) stored during binding. The system then connects and operates normally. If the transmitter is turned on ﬁrst—the transmitter scans the 2.4GHz band and acquires two open channels. The receiver scans the 2.4GHz band looking for the previously stored GUID and when it locates the speciﬁc GUID code and conﬁrms uncorrupted repeatable packet information, the system connects and normal operation takes place. Typically this takes 2 to 6 seconds.

2. Q: Sometimes the system takes longer to connect and sometimes it doesn’t connect at all?

A: In order for the system to connect (after the receiver is bound) the receiver must receive a large number

of consecutive uninterrupted perfect packets from the transmitter in order to connect. This process is purposely critical of the environment ensuring that it’s safe to ﬂy when the system does connect. If the transmitter is too close to the receiver (less than 4 ft.) or if the transmitter is located near metal objects

(metal Tx case, the bed of a truck, the top of a metal work bench, etc.) connection will take longer and in some cases connection will not occur as the system is receiving reﬂected 2.4GHz energy from itself and is interpreting this as unfriendly noise. Moving the system away from metal objects or moving the transmitter away from the receiver and powering the system again will cause a connection to occur. This only happens during the initial connection. Once connected the system is locked in and should a loss of signal occur (failsafe) the system connects immediately (4ms) when signal is regained.

3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is that correct?

A: All DSM receivers have an operational voltage range of 3.5 to 9.6 volts. With most systems this

is not a problem as in fact most servos cease to operate at around 3.8 volts. When using multiple high-current draw servos with a single or inadequate battery/power source, heavy momentary loads can cause the voltage to dip below this 3.5-volt threshold thus causing the entire system (servos and receiver) to brown out. When the voltage drops below the low voltage threshold (3.5 volts), the DSM receiver must reboot (go through the startup process of scanning the band and ﬁnding the transmitter) and this can take several seconds. Please read the receiver power requirement section as this explains how to test for and prevent this occurrence.

4. Q: Sometimes my receiver loses its bind and won’t connect requiring rebinding. What happens if the bind is lost in ight?

A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand that

during the binding process the receiver not only learns the GUID (code) of the transmitter but the transmitter learns and stores the type of receiver that it’s bound to. If the transmitter is placed into bind mode, the transmitter looks for the binding protocol signal from a receiver. If no signal is present, the transmitter no longer has the correct information to connect to a speciﬁc receiver and in essence the transmitter has been “unbound” from the receiver. We’ve had several DX7 customers that use transmitter stands or trays that unknowingly depress the bind button and the system is then turned on losing the necessary information to allow the connection to take place. We’ve also had DX7 customers that didn’t fully understand the range test process and pushed the bind button before turning on the transmitter also causing the system to “lose its bind.”

After Connection

• When the transmitter is turned on and after the receiver connects to the transmitter, normal control

of all channels occurs.

• After the system makes a connection, if loss of signal occurs Preset Failsafe drives all servos to their

preset failsafe positions set during binding.

Receiver Power System Requirements

Inadequate power systems that are unable to provide the necessary minimum voltage to the receiver during ﬂight have become the number one cause of in-ﬂight failures. Some of the power system components that affect the ability to properly deliver adequate power include

• Receiver battery pack (number of cells, capacity, cell type, state of charge)

• The switch harness, battery leads, servo leads, regulators etc.

The AR9300 has a minimum operational voltage of 3.5 volts; it is highly recommended the power system be tested per the guidelines below.

Recommended Power System Test Guidelines

If a questionable power system is being used (e.g. small or old battery that may not support highcurrent draw, etc.), it is recommended that a voltmeter be used to perform the following tests.

Note: The Spektrum Flight Log (SPM9540) is the perfect tool to perform the test below.

Plug the Flight Log into an open channel port in the receiver and with the system on, load the

control surfaces (apply pressure with your hand) while monitoring the voltage at the receiver. The voltage should remain above 4.8 volts even when all servos are heavily loaded.

Note: The latest generations of Nickel-Metal Hydride batteries incorporate a new chemistry

mandated to be more environmentally friendly. These batteries when charged with peak detection fast chargers have tendencies to false peak (not fully charge) repeatedly. These include all brands of NiMH batteries. If using NiMH packs, be especially cautious when charging, making absolutely sure that the battery is fully charged. It is recommended to use a charger that can display total charge capacity. Note the number of mAh put into a discharged pack to verify it has been charged to full capacity.

QuickConnect™ With Brownout Detection

Your AR9300 features QuickConnect with Brownout Detection.

• Should an interruption of power occur (brownout), the system will reconnect immediately when

power is restored (QuickConnect).

• The LED on the receiver will ash slowly indicating a power interruption (brownout) has occurred.

• Brownouts can be caused by an inadequate power supply (weak battery or regulator), a loose

connector, a bad switch, an inadequate BEC when using an electronic speed controller, etc.

• Brownouts occur when the receiver voltage drops below 3.5 volts thus interrupting control as the

servos and receiver require a minimum of 3.5 volts to operate.

How QuickConnect With Brownout Detection Works

• When the receiver voltage drops below 3.5 volts the system drops out (ceases to operate).

• When power is restored the receiver immediately attempts to reconnect to the last two frequencies

that it was connected to.

• If the two frequencies are present (the transmitter was left on), the system reconnects typically in

about 4/100 of a second.

QuickConnect with Brownout Detection is designed to allow you to ﬂy safely through most shortduration power interruptions; however, the root cause of these interruptions must be corrected before the next ﬂight to prevent catastrophic safety issues.

Note: If a brownout occurs in ﬂight it is vital that the cause of the brownout be determined and corrected.
