3Safety PrecautionsRunning (Sailing) Safety PrecautionsWarningConduct TestsPrior to operation always perform a range test.Even one abnormality in the R/C system may cause loss of control.[Range Test Procedure]Have a friend hold the model, or place on a stand where the wheels or prop can notcome in contact with any object. Collapse the transmitter antenna and operate from adistance of about 100 feet. Be sure to check the movement of each servo to make sureit follows the movement of the steering wheel and throttle trigger. If the servos do notfollow the commands from the transmitter or any type of interference is detected, DoNot operate the model.Fully extend the transmitter antenna.If the transmitter antenna is not fully extended, range will be reduced and control maybe lost.ProhibitedDo not operate two or more models on the same frequency at the same time.Operation of two or more models on the same frequency at the same time will causeinterference and loss of control of both models.AM, FM and PCM are different methods of modulation. Nonetheless the same fre-quency can not be used at the same point in time, regardless of the signal format.Do not operate outdoors on rainy daysNever operate in the rain or run through puddles.The transmitter, receiver, batteries and most servos, and speed controls are not wa-terproof. Contact with any type of moisture or immersion in water or snow will causedamage along with possible loss of control. Should any type of moisture enter anycomponent of the system, immediately stop using the R/C system and return it to ourservice center for inspection.ProhibitedDo not operate when visibility is limited.Should you lose sight of the model, a collision or other dangerous situation may occur.ProhibitedDo not operate near people or roads.Do not operate near high tension power lines or communication broadcasting anten-nas.Prior to the operation of any model be sure the area you plan to use is safe. Be awareof all objects that may be in the path of your model. Do not operate the model wherepeople or any type of moveable object could stray in the path of your model. Controlloss due to interference, component failure, loss of sight or low battery voltage couldresult in serious injury to yourself and others as well as damage to your model.ProhibitedDo not operate your R/C system within 1 mile of another site where radio control activ-ity may occur.Interference from other R/C systems will cause loss of control.
4Safety PrecautionsProhibitedDo not operate when you are tired, not feeling well or under the influence of alcohol ordrugs.Your judgment is impaired and could result in a dangerous situation that may causeserious injury to yourself and others.Before you turn on the power switch on the transmitter, always check to see that thetrigger is at the neutral position. Always turn the transmitter on first, then the receiver.When you turn the system off, always turn the receiver off first and then the transmit-ter. This step is very important. Always follow this procedure.If this procedure is not followed, injury to yourself and others as well as loss of controlcould occur.Adjustment NoteMake all adjustments to the radio control system with engine not running, or the elec-tric motor disconnected.If the engine is running or the motor is connected while adjustments are made, themodel may run out of control.Remove the main battery source from electric powered models when they are notbeing used.Should you accidentally leave the receiver switch on, the model could run out of control.CautionDo not touchDo not touch the engine, motor, speed control or any part of the model that will gener-ate heat while running.Touching hot parts will result in serious burns.Storage and Disposal Safety PrecautionsWarning(When using a Ni-cad battery to power your system)At the end of a day's operation, store the system with Ni-cad battery discharged. Besure to recharge the system before it is used again.You should fully discharge your system's batteries periodically to prevent a conditioncalled "memory". For example, if you only make two runs in a day or you regularly usea small amount of battery's capacity, the memory effect can reduce the actual capacityeven if the battery is charged for the recommended amount of time.ProhibitedDo not throw a Ni-cad battery into a fire. Do not disassemble or attempt to repair a Ni-cad battery pack.Overheating, damage and acid leakage may lead to burns, loss of eye sight as well asnumerous other types of injuries. The electrolyte in Ni-cad batteries is a strong alkali.Should you get even the smallest amount of the electrolyte in your eyes, Do Not rub,wash immediately with water, and seek medical attention at once. The electrolyte cancause blindness. If electrolyte comes in contact with your skin or clothes, wash withwater immediately.
5Safety PrecautionsOther Safety PrecautionsCautionWhen operating two or more models at the same time, have a third person act as aspotter. They will be in charge of safety and you should follow their instructions.Beginners should receive instructions regarding safety and operation from an experi-enced modeler.Use genuine Futaba parts only.Always use only genuine Futaba receivers, servos, and electronic speed controls,along with other optional parts and components.Futaba will not be held responsible for damages caused by other than genuine Futabaparts and components. Use only genuine Futaba parts and components listed in theinstruction manual and catalog.(When using a Ni-cad battery to power your system)ProhibitedDo not short circuit the Ni-cad battery terminals.Short circuiting the terminals will lead to sparks and overheating and could cause a fireand burns as well.CautionProhibitedDo not store your R/C system where it will be exposed to the following conditions.• Extreme heat or coldness• Exposed to direct sunlight• Where humidity is high• Where vibration is prevalent• Where dust is prevalent• Where there is steam and condensation• Where the system would be exposed to engine exhaustStoring your R/C system under adverse conditions could cause deformation and nu-merous other problems with operation.(When using a Ni-cad battery to power your system)CautionWhen disposing Ni-cad batteries, cover any exposed contacts with some type of insu-lation to prevent short circuit.Improper disposal could cause fire.

Payvery close attention to the polaritymarkings and reinsert accordingly.4Slide the battery cover back onto thecase.Check:Turn the power switch on the trans-mitter to the ON position. Check thebattery voltage display on the LCDscreen.If the voltage is low, check the batter-ies for insufficient contact in the caseor incorrect battery polarity.CautionAlways be sure you reinsert the bat-teries in the correct polarity order.If the batteries are loaded incorrectly , thetransmitter may be damaged.When the transmitter will not beused for any short or long period oftime, always remove the batteries.If the batteries do happen to leak , clean thebattery case and contacts thoroughly. Makesure the contacts are free of corrosion.Low Battery Alarm:If the transmitter battery voltagedrops below 8.5V an alarm will soundand "LOW" will be displayed on theLCD screen.The low battery alarm is meant to be asafety feature only. Do NOT operateyour radio below 9V. Always shutyour radio off as soon as possible af-ter the low battery warning tone toavoid loss of control.
9Assembly / AdjustmentAssembly / AdjustmentReceiver and Servo ConnectionAs you connect the receiver, servos and other components, do so in accordance with the"Assembly Precautions".Connections when a E.S.C. MC230CR or MC330CR are used.Steering ServoThrottle ServoReceiverReceiverPower SwitchTo Receiver BatterySteering ServoE.S.C.Power SwitchConnects to MotorConnects to BatteryGas Powered ModelAssembly PrecautionsWarningCheckCheck the receiver, servos, and battery connectors, to be sure they are firmly con-nected.If a connector is not fully inserted, vibration may cause the connector to work loosewhile the model is operating. This will result in loss of control.CheckOperate each servo horn over its full stroke and check to see that the linkage does notbind or is not too loose.Excessive force applied to the servo horn by binding or poor installation may lead toservo problems and result in loss of control.
10Assembly / AdjustmentInstall electronic speed control heat sinks as well as other components that conductelectricity so they can not come in contact with aluminum, carbon fiber or other mate-rials that conduct electricity.If, for example, the speed control came loose while the model was running andtouched an aluminum chassis, a short circuit may occur that would cause irreparabledamage to the system as well as loss of control.Installation NoteNoise suppression capacitors should be installed on almost all motors.If the proper capacitors are not installed, high frequency noise will reduce range andcause loss of control along with various other problems.Installation NoteInspect all linkage installations and any point where metal could come in contact withother metal parts. Make sure these parts do not touch other metal parts under vibra-tion.Should a linkage or other metal parts come in contact with other metal parts undervibration, the high frequency noise generated by this contact will cause interferenceand possible loss of control.CautionDisassembly ProhibitedDo Not disassemble any part of this system that is not specified in the instructionmanual.Futaba will not be responsible for any damage due to improper disassembly of anypart of the radio control system.ProhibitedThe receiver antenna may seem long. Do not cut or alter from the original length.If the receiver antenna length is altered, the receiver will be adversely effected. Thereceiver will become considerably more susceptible to interference and high fre-quency noise which will result in loss of range and control.Installation Note(Electric Cars and Boats)Isolate the receiver from vibration by attaching to the chassis or mounting plate withthick double sided tape.(Gas Powered Cars and Boats)Isolate the receiver from vibration by wrapping it in foam rubber or similar type cush-ioning material. Protect the unit from water damage by placing it in a plastic bag orwaterproof radio box.The receiver contains precision electronic parts. These parts are vulnerable to vibra-tion and shock. Any contact with moisture (water or condensation) may cause receivermalfunction and loss of control.Installation NoteKeep all devises that omit high frequency noise, such as motors, batteries, and wiringthat handles heavy current loads, at least 1/2 inch away from the receiver and thereceiver antenna.High frequency noise will cause a decrease in operating range and could cause loss ofcontrol.Use genuine Futaba parts only.Use only genuine Futaba crystal sets as specified in this instruction manual.The use of other than Futaba crystal sets will result in decrease of range as well asloss of control. There are separate crystals for the Transmitter and Receiver. Thereare also crystal sets for AM, FM and Dual Conversion FM. Use only single conversionAM crystal sets with this system.Changing crystals in 72-75 MHz transmitter is illegal. However, 27 MHz is allowable.(For U.S.A.)
