Running (Sailing) Preparations Safety Precautions
(When using a Ni-cad battery to power your system) (Charging)
When using a Ni-cad battery to power your system, always charge and check the battery voltage prior to operation. Should the battery discharge below the minimum voltage level, control will be lost.
(When using a Ni-cad battery to power your system)
When the charger is not in use, disconnect from the outlet. To prevent accidents, overheating and short circuits
Running (Sailing) Safety Precautions
Do 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 cause interference and loss of control of both models. AM, FM and PCM are different methods of modulation. Nonetheless the same frequency can not be used at the same point in time, regardless of the signal format. Never operate in the rain or run through puddles. The transmitter, receiver, batteries and most servos, and speed controls are not waterproof. Contact with any type of moisture or immersion in water or snow will cause damage along with possible loss of control. Should any type of moisture enter any component of the system immediately stop using the R/C system and return to our service center for inspection. Do not operate when visibility is limited. Should you loss sight of the model a collision or other dangerous situation may occur. Do not operate near people or roads. Do not operate near high tension power lines or communication broadcasting antennas. Prior to the operation of any model be sure the area you plan to use is safe. Be aware of all object that may be in the path of your model. Do not operate the model where people or any type of moveable object could stray in the path of your model. Control loss due to interference, component failure, loss of sight or low battery voltage could result in serious injury to yourself and others as well as damage to your model. Do not Operate your R/C system within 1 mile of another site where radio control activity may occur. Interference from other R/C systems will cause loss of control. Do not operate when you are tired, not feeling well or under the influence of alcohol or drugs. Your judgement is impaired and could result in a dangerous situation that may cause serious injury to yourself and others.

(Conduct Tests)

Prior to operation always preform 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 not come in contact with any object. Collapse the transmitter antenna and operate from a distance of about 10 yards. Be sure to check the movement of each servo to make sure they follow the movement of the steering and throttle stick. If the servos do not follow the commands from the transmitter or any type of interference is detected, Do Not operate the model. Fully extend the transmitter antenna. If the transmitter antenna is not fully extended range will be reduced and control may be lost.

SAFETY PRECAUTIONS 3

Before you turn on the power switch on the transmitter, always check to see that the stick 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 then the transmitter. 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 control could occur.

(Adjustment Note)

Make all adjustments to the radio control system with engine not running, or the electric motor disconnected. If the engine is running or the motor is connected while adjustments are made the model may run out of control. Remove the main battery source from electric powered models when they are not being used. Should you accidently leave the receiver switch on the model could run out of control.

SAFETY PRECAUTIONS 4

Do not touch the engine, motor, speed control or any part of the model that will generate heat while running. Touching hot parts will result in serious burns.
Storage and Disposal Safety Precautions
Do 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 as numerous 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, seek medical attention at once. The electrolyte can cause blindness. If electrolyte comes in contact with your skin or clothes, wash with water immediately.
At the end of a days operation store the system with Ni-cad battery discharged. Be sure to recharge the system before it is used again. You should fully discharge your systems batteries periodicity to prevent a condition called "memory effect". For example if you only make two run in a day or you regularly use a small amount of the batteries capacity, the memory effect can reduce the actual capacity even if the battery is charged for the recommended amount of time.

Do 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 exhaust Storing your R/C system under adverse conditions could cause deformation and numerous other problems with operation.
When disposing Ni-cad batteries, cover any exposed contacts with some type of insulation to prevent short circuit. Improper disposal could cause fire. *Special Note! Some states require special handling when Ni-cad batteries are disposed. Contact the State Agency responsible for recycling hazardous waste for the procedures in your state.

Other Safety Precautions

Do not short circuit the Ni-cad battery terminals. Short circuiting the terminals will lead to sparks and overheating and could cause a fire and burns as well. When operating two or more models at the same time, have a third person act as a spotter. They will be in charge of safety and you should follow their instructions. Beginners should receive instructions regarding safety and operation from an experienced modeler. Always use only genuine Futaba receiver, servos, electronic speed controls along with other optional parts and components. Futaba will not be held responsible for damages caused by other than genuine Futaba parts and components. Use only genuine Futaba parts and components listed in the instruction manual and catalog.

(BATT) To receiver battery
Connect the battery in accordance with instructions provided with model you are installing this system in. Use the R2-BSS-N battery holder (Supplied with systems sold with 2 servos only) to match your application. If your model has a mechanical type speed control (Servo Driven for electric powered models) inspect this component for a power supply regulator or voltage dropping Diode. These device's will cause a voltage drop to the receiver. Be sure to remove them prior to installation in your model.

ASSEMBLY / ADJUSTMENT 9

Assembly Precautions
Do not cut or alter from the original length. If the receiver antenna length is altered, the receiver will be adversely effected. The receiver will become considerably more susceptible to interference and high frequency noise which will result in loss of range and control. Check the receiver, servos, and battery connectors, to be sure they are firmly connected. If a connector is not fully inserted, vibration may cause the connector to work loose while the model is operating. This will result in loss of control. Operate each servo horn over its full stroke and check to see that the linkage does not bind or is not too loose. Excessive force applied to the servo horn by binding or poor installation may lead to servo problems and cause result in loss of control. (Electric Car's and Boat's) Isolate the receiver from vibration by attaching to the chassis or mounting plate with thick double sided tape. (Gas Powered Car's and Boat's) Isolate the receiver from vibration by wrapping it in foam rubber or similar type cushioning material. Protect the unit from water damage by placing it in a plastic bag or waterproof radio box. The receiver contains precision electronic parts. These parts are vulnerable to vibration and shock. Any contact with moisture (water or condensation) may cause receiver malfunction and loss of control. Keep all devices that may omit high frequency noise, such as motor's, batteries, and wiring that handle heavy current loads, at least 1/2 inch away from the receiver and receiver antenna. High frequency noise will cause a decrease in operating range and could cause loss of control. Use only genuine Futaba crystal set's as specified in this instruction manual. The use of other than Futaba crystal set's will result in decrease of range as well as loss of control. There are separate crystal's for the Transmitter and Receiver, there are also crystal set's for AM, FM and Dual Conversion FM. Use only single conversion AM crystal set's with this system. Changing crystals in 75 MHz transmitter is illegal, however 27 MHz is allowable. (For U.S.A.) Install electronic speed control heat sinks as well as other components that conduct electricity so they can not come in contact with aluminum, carbon fiber or other materials that conduct electricity. If for example the speed control came loose while the model was running and touched an aluminum chassis a short circuit may occur that would cause irreparable damage to the system as well as loss of control.

Noise suppression capacitors should be installed on almost all motors. If the proper capacitors are not installed, high frequency noise will reduce range and cause loss of control along with various other problems. Inspect all linkage installations and any point where metal could come in contact with other metal parts. Make sure these parts do not touch other metal parts under vibration. Should a linkage or other metal parts come in contact with other metal parts under vibration the high frequency noise generated by this contact will cause interference and possible loss of control.
Do Not disassemble any part of this system that is not specified in the instruction manual. Futaba will not be responsible for any damage due to improper disassembly of any part of the radio control system.

DESCRIPTION OF FUNCTIONS

Steering Trim
Steering neutral adjustments can be made by moving the Steering trim to the left or right.

Racers Tip

When you install a servo always check to be sure the servo is at its neutral position. Adjust the servo horn hole position and linkage so both are parallel. When a servo saver is used place it as close to center position as possible. Be sure the steering trim on the transmitter is at the neutral position.

Servo Saver

Trim Operation and Maximum Travel
Changing the trim can effect the overall settings, when adjustments are made with the trims recheck your installation for maximum servo travel.

Parallel

When Trim Usage is Extreme
If it takes most of your trim movement to get a servo to the neutral position, reposition the servo horn or servo saver on the servo and inspect your linkage installation.

Direct Servo Saver Horn

Throttle Trim
Throttle neutral adjustments can be made moving the throttle trim to the up or down.
When using a electronic speed control set the throttle trim to neutral and make adjustments to the speed control. On a gas powered model set the trim to neutral and adjust the linkage to the point where the carburetor is fully closed in accordance with the engine instruction manual.
Trim Operation and Travel
Trim adjustments will effect the overall servo travel, check the brake side (backward) movement when changes are made.

Carburetor Fully Closed

When Trim Movement is Extreme
If you use most of the trim movement to get the servo to the neutral position , recenter the servo horn closer to the neutral position and inspect your throttle linkage.
