Optional location 2 4GHz Friendly Fuselage with Molded Non Carbon Wing 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 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 fus
3. 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 non amplified 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 e Prevents flyaways should the signal be lost e Eliminates the possibility of over driving servos Receiver Power Only e 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 th

7. ace 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 th
8. d 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 e Should an interruption of power occur brownout the system will reconnect immediately when power is restored QuickConnect e The LED on the receiver will flash slowly indicating a power interruption brownout has occurred e 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 e 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 e When the receiver voltage drops below 3 5 volts the system drops out ceases to op
9. d 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
10. 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 tur
