Special note for 2.4GHz FHSS radio system setupReceiver ’s Antenna installationSince the 2.4GHz have different characteristics than that of the conventional frequencies,please read this section carefully to enjoy safe ﬂight with the 2.4GHz system.The MR-600 has two antennas. These antennas have a diversity function to decrease thechance of a receiving error.The wavelength of the 2.4GHz is much shorter than that of the conventional frequencies,it is very susceptible to loss of signal which results in a receiving error. In order to avoidthis phenomenon, the MR-600 adopted a diversity antenna system.To obtain the best results of the diversity function, please refer to the followinginstructions;1. The two antennas must be kept as straight aspossible. Otherwise it will reduce the effectiverange.2. The two antennas should be placed at 90 degreesto each other. This is not a critical ﬁgure, but themost important thing is to keep the antennas awayfrom each other as much as possible. Larger models can have large metal objectsthat can attenuate the RF signal. In this case the antennas should be placed at bothsides of the model. Then the best RF signal condition is obtained at any ﬂying attitude.3. The antennas must be kept away from conductive materials, such as metal and carbonby at least a half inch. The coaxial part of the antennas does not need to follow theseguidelines, but do not bend it in a small radius.4. Keep the antennas away from the motor, ESC, and other noise sources as muchas possible.* The two antennas should be placed at90 degrees to each other.* The main purpose of the photodemonstrates how the antenna shouldbe placed. For actual installation thereceiver must be wrapped with asponge or placed with floating materialto protect it from vibration.eThe receiver contains precision electronic parts. It is the most delicate radiocomponent on-board the model and should be protected from vibration,shock and temperature extremes. To protect the receiver, wrap it in R/C foamrubber or other vibration-absorbing material. If appropriate, waterproof thereceiver by placing it in a plastic bag and closing the open end with a rubberband before wrapping it in foam. If moisture enters the receiver, intermittentoperation or a failure may result. Wrapping the receiver in a plastic bag alsoprotects it from fuel and exhaust residue which, in some models, can work itsway into the fuselage.

Transmitter antenna1. The transmitter antenna is adjustableso please make sure that the antenna isnever pointed directly at the modelwhen ﬂying as this creates a weak signalfor the receiver.2. Keep the antenna perpendicular to thetransmitter's face to create a better RFcondition for the receiver. Of coursethis depends on how you hold thetransmitter, but in most cases, adjustingthe transmitter antenna so that it is perpendicular to the face will give the bestresults. Please adjust the transmitter antenna to the way you hold the transmitter.3. NEVER grip the antenna when ﬂying as this degrades RF quality.FCC Compliance StatementThis equipment has been tested and found to comply with the limits for a ClassB digital device, pursuant to Part 15 of the FCC Rules.

Fail Safe Setup , Continue...4. To confirm that fail safe is working properly, the ESC will go in to the neutral position and the vehicle will not move when you shut off the transmitter. See page 5 and check the Fail Safe function working properly. You do not need to repeat this procedure each time you run.5. To confirm that fail safe is working properly, full brake should automatically be applied when you shut off the transmitter. See page 5 and check the Fail Safe function working properly. You do not need to repeat this procedure each time you run.Turn off receiver first, then turn off transmitter.Binding SetupFail Safe SetupProgramming a receiver to recognize the code of only one specitic transmitter.The fail safe system has been setup at the factory,but you should becomefamiliar with the function of the fail safe and check the operation before running. When fail safe is operating,the red LED will continuously flash.1. Place the transmitter and the receiver close to each other (within one meter). Turn the power switch on the transmitter to the ON position.2. Press and hold the receiver setup button,then turn the power switch to the ON position. The receiver LED will flash quickly. Release the setup button after 1 second.3. Press and hold the binding button on the transmitter for 1 second until the LED on the receiver is continuously lit.1. Turn the power switch to the ON position on the transmitter. Press the setup button on the receiver then release. LED will flash.2. Leave throttle trigger in neutral position, and press the setup button. The LED will flash quickly.Once the receiver LED remains lit, then release the setup button on the receiver.3. Hold full brake on the transmitter, and press the setup button. The LED will flash quickly. Release full brake on the transmitter once the receiver LED remains lit, then release the setup button on the receiver.If you change transmitters or add a receiver, you must re-bind before operating your vehicle.The fail safe can not completely protect your car.Any new binding of transmitter & receiver will clear the presetfail safe.

The transmitter has a individual randomize ID that is created in the factory, Even it isalmost have no chance to meet the same ID transmitter in the same fly field,he transmitter has an ID set up function.You can go back to the original factory set ID by hin case it doeshappen. Tolding the “PDM” when turn on thetransmitter, without press the “PDM” bottom, turn it off and on again to get back theoriginal ID.Change the transmitter IDRange check the radioA range check must be performed before the first flight of a new model. It is not necessaryto do a range check before every flight (but is not a bad idea to perform a range checkbefore the first flight of each day). A range check is the final opportunity to reveal anyradio malfunctions, and to be certain the system has adequate operational range.1. There is "Power Down Mode" build in for doing a ground range check To activate the"Power Down Mode" by pressing the “PDM” button on the right upper panel of thetransmitter. The Green LED will turn off to indicate the PDM is working. During thismode, the RF power is reduced so the range test can be performed.2. Walk away from the model while simultaneously operating the controls. Have anassistant stand by the model and signal what the controls are doing to confirm thatthey operate correctly. You should be able to walk 30 - 50 paces approximately fromthe model without losing control.3. If everything operates correctly, return to the model. The "Power Down Mode"continues for 60 seconds and after that the power will go back to the normal level.To exit the "Power Down Mode" before the 60 seconds, press the "PDM" key again.4. NEVER start flying when the "Power Down Mode" is active.

Transmitter Operation and Movement of Each ServoBefore making any adjustments, learn the operation of the transmitter and themovement of each servo. (In the following descriptions, the transmitter is assumedto be in the standby state.)AILERON OPERA TIONWhen the aileron stick is moved to theright, the right aileron is raised and the leftaileron is lowered, relative to the directionof flight, and the plane turns to the right.When the aileron stick is moved to the left,the ailerons move in the opposite direction.To level the plane, the aileron stick mustbe moved in the opposite direction.When the aileron stick is tilted and held,the plane will roll.ELEVATOR OPERA TIONWhen the elevator stick is pulled back, thetail elevator is raised and the tail of theplane is forced down, the air flow appliedto the wings is changed, the lifting force isincreased, and the plane climbs (UP opera-tion). When the elevator stick is pushedforward, the elevator is lowered, the tail ofthe plane is forced up, the air flow appliedto the wings is changed, the lifting force isdecreased, and the plane dives (DOWNoperation).THROTTLE OPERA TIONWhen the throttle stick is pulled back, theengine throttle lever arm moves to theSLOW (low speed) side. When the throttlestick is pushed forward, the throttle leverarm moves to the HIGH (high speed) side.RUDDER OPERA TIONWhen the rudder stick is moved to theright, the rudder moves to the right and thenose points to the right, relative to thedirection of flight. When the rudder stick ismoved to the left, the rudder moves to theleft and the nose points to the left and thedirection of travel of the plane changes.Elevator(ch2)Aileron(ch1)Thr ottle(ch3)Right(Viewed from the rear)Engine throttle lever movesto the high speed side.Engine throttle lever movesto the low speed side.Left RightDown(Mode 1) (Mode 2)UpHighLow(Mode 1) (Mode 2)LeftLeft LightRightDown DownUp UpHigh HighLow LowLeft

This section describes the installation method and adjustment method after installa-tion when installing the receiver, servos, etc. to the plane.ConnectionsConnection example is shown below.ADJUSTMENT AND INSTALLATIONConnection ExampleReceiverMR-600Aileron(CH1)Elevator(CH2)Thr ottle(CH3)Rudder(CH4)Receiver switchReceiver battery holder*Insert four batteries.*When using 5 or more servos,use the nicd battery sold separately.*The number of servos dependson the set.

WARNINGConnector ConnectionInsert the receiver, servo, andbattery connectors fully andfirmly.If vibration, etc. causes a connector towork loose during flight, the plane maycrash.Receiver Vibrationpr oofing/ Waterpr oofingVibrationproof the receiver bywrapping it in sponge rubber orsome such material. If the re-ceiver may get wet, waterproofit by placing it in a plastic bag.If the receiver is subjected to strong vibra-tion and shock, or gets wet, it may operateerroneously and cause a crash.Receiver AntennaDo not cut or bundle the re-ceiver antenna. Also, do notbundle the antenna togetherwith the servo lead wires.Cutting or bundling the receiver antennawill lower the receiver sensitivity andshorten the flight range and cause a crash.<Antenna installation>For aircraft, attach the antenna to the top ofthe tail.Servo Thr owOperate each servo horn overits full stroke and adjust so thatthe pushrod does not bind or isnot too loose.Unreasonable force applied to the servohorn will adversely affect the servo anddrain the battery quickly.Servo InstallationInstall the servos to the servomount, etc. through a rubbergrommet. Also install the servosso that the servo case does notdirectly touch the servo mountor other parts of the fuselage.Power Switch InstallationWhen installing a receiver power switch to thefuselage, cut a rectangular hole somewhatlarger than the full stroke of the switch knoband install the switch so it moves smoothlyfrom ON to OFF.Also install the switch where it will not comeinto direct contact with engine oil, dust, etc.Generally, install the switch to the fuselage atthe side opposite the muffler exhaust.

The operating dir ection, neutral position, and steering angle of each servo ar e adjusted.CAUTIONThe basic linkage and adjustments of the fuselage conform to the fuse-lage design drawings and kit instruction manual. Be sure that the centerof gravity is at the prescribed position.Adjustment Pr ocedur eBefore making any adjustments, setall the SERVO REVERSER switcheson the front of the transmitter to thelower (NOR) position. (Switch theswitches with a small screwdriver,etc.)Turn on the transmitter and receiverpower switches and make the follow-ing adjustments:1Check the dir ection of opera-tion of each servo.If a servo operates in the wrong direction,switch its SERVO REVERSER switch. (Thedirection of operation can be changed withoutchanging the linkage.)*Note that the direction of the aileron servo iseasily mistaken. (Page 10)2Check the aileron, elevator ,and rudder neutral adjustmentand left-right (up-down) thr ow.Check that when trimmed to the center, theservo horn is perpendicular to the servo andcheck the neutral position of the fuselagecontrol surfaces (aileron, elevator, rudder,etc.). If the neutral position has changed, resetit by adjusting the length of the rod with thelinkage rod adjuster.When the throw is unsuitable (different fromsteering angle specified by the kit instructionmanual), adjust it by changing the servo hornand each control surface horn rod .3Check the engine thr ottle(speed adjustment) linkage.Change the servo horn installation positionand hole position so that the throttle is openedfully when the throttle stick is set to HIGH(forward) and is closed fully when the throttlestick and throttle trim are set for maximumslow (backward position and lower position,respectively).4After all the linkages havebeen connected, recheck theoperating dir ection, thr ow, etc.*Before flight, adjust the aircraft in accor-dance with the kit and engine instructionmanuals.5Fly the plane and trim eachservo.Adjustments
