＜Introduction ＞
Ni-MH/Ni-Cd Battery
󾻫Charge the batteries! (See Charging the Ni-Cd batteries, for details.) Always recharge the transmitter and
receiver batteries before each ying session. A low battery will soon die potentially, causing loss of control
and a crash. When you begin your ying session, reset your 8FG’s built-in timer, and during the session
pay attention to the duration of usage.
󾻫Stop ying long before your batteries become low on charge. Do not rely on your radio’s low battery
warning systems, intended only as a precaution, to tell you when to recharge. Always check your
transmitter and receiver batteries prior to each ight.
Where to Fly
We recommend that you y at a recognized model airplane ying eld. You can nd model clubs and elds
by asking your nearest hobby dealer, or in the US by contacting the Academy of Model Aeronautics.
You can also contact the national Academy of Model Aeronautics (AMA), which has more than 2,500
chartered clubs across the country. Through any one of them, instructor training programs and insured
newcomer training are available. Contact the AMA at the address or toll-free phone number below.

Ni-MH/Ni-Cd Battery Safety and Handling instructions
IMPORTANT!
Use only the Futaba special charger included with this set or other chargers approved by Futaba to
charge the Ni-MH batteries in the 8FG transmitter and Ni-Cd batteries included with this set.
It is important to understand the operating characteristics of Ni-MH/Ni-Cd batteries.Always read the
specications printed on the label of your Ni-MH/Ni-Cd battery and charger prior to use. Failure to follow the
proceeding precautions can quickly result in severe, permanent damage to the batteries and its surroundings and
possibly result in a FIRE!
IMPORTANT PRECAUTIONS
󾻭Do not attempt to disassemble Ni-MH/Ni-Cd packs or cells.
󾻭Do not allow Ni-MH/Ni-Cd cells to come in contact with moisture or water at any time.
󾻫Always provide adequate ventilation around Ni-MH/Ni-Cd batteries during charge, discharge, while in
use, and during storage.
󾻭Do not leave a Ni-MH/Ni-Cd battery unattended at any time while being charged or discharged.
󾻭Do not attempt to charge Ni-MH/Ni-Cd batteries with a charger that is NOT designed for Ni-MH/Ni-Cd
batteries, as permanent damage to the battery and charger could result.
󾻫Always charge Ni-MH/Ni-Cd batteries in a reproof location. Do not charge or discharge Ni-MH/Ni-Cd
batteries on carpet, a cluttered workbench, near paper, plastic, vinyl, leather or wood, or inside an R/C
model or full-sized automobile! Monitor the charge area with a smoke or re alarm.
󾻭Do not charge Ni-MH/Ni-Cd batteries at currents greater than the “1C” rating of the battery (“C” equals
the rated capacity of the battery).
󾻭Do not allow Ni-MH/Ni-Cd cells to overheat at any time! Cells which reach greater than 140 degrees
Fahrenheit (60°C) should be placed in a reproof location.
󾻫Ni-MH/Ni-Cd cells will not charge fully when too cold or show full charge.
󾻫It is normal for the batteries to become warm during charging, but if the charger or battery becomes
excessively hot disconnect the battery from the charger immediately!! Always inspect a battery which has
previously overheated for potential damage, and do not re-use if you suspect it has been damaged in any
way.
󾻭Do not use a Ni-MH/Ni-Cd battery if you suspect physical damage has occurred to the pack. Carefully
inspect the battery for even the smallest of dents, cracks, splits, punctures or damage to the wiring and
connectors. DO NOT allow the battery’s internal electrolyte to get into eyes or on skin—wash affected
areas immediately if they come in contact with the electrolyte. If in doubt, place the battery in a re-proof
location for at least 30 minutes.
󾻭Do not store batteries near an open ame or heater.
󾻭Do not discharge Ni-MH/Ni-Cd batteries at currents which exceed the discharge current rating of the
battery.
󾻫Always store Ni-MH/Ni-Cd cells/packs in a secure location away from children.
󾻭Never remove the SD card or turn off power while
entering data.
󾻭Never store the SD card where it may be subject
to strong static electricity or magnetic elds.
󾻭Do not expose the SD card to direct sunlight,
excessive humidity or corrosive environments.
󾻭Do not expose the SD card to dirt, moisture, water
or uids of any kind.
󾻫Always hold the SD card by the edges during
installation and removal.
󾻫Be certain to insert the SD card in the correct
direction.

＜Introduction ＞
At the ying eld
To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:
1. Pull throttle stick to idle position, or otherwise disarm your motor/engine.
2. Turn on the transmitter power and allow your transmitter to reach its home screen.
3. Conrm the proper model memory has been selected.
4. Turn on your receiver power.
5. Test all controls. If a servo operates abnormally, don’t attempt to y until you determine the cause of the
problem.
Test to ensure that the FailSafe settings are correct after adjusting them. Turn the transmitter off and
conrm the proper surface/throttle movements. Turn the transmitter back on.
6. Start your engine.
7. Complete a full range check.
8. After ying, bring your throttle stick to idle position, engage any kill switches or otherwise disarm your
motor/engine.
9. Turn off receiver power.
10. Turn off transmitter power.
If you do not turn on your system in this order, you may damage your servos or control surfaces, ood your
engine, or in the case of electric-powered or gasoline-powered models, the engine may unexpectedly turn on
and cause a severe injury.
󾻫While you are getting ready to y, if you place your transmitter on the ground, be sure that the wind
won't tip it over. If it is knocked over, the throttle stick may be accidentally moved, causing the engine to
speed up. Also, damage to your transmitter may occur.
󾻫In order to maintain complete control of your aircraft it is important that it remains visible at all times.
Flying behind large objects such as buildings, grain bins, etc. is not suggested. Doing so may result in the
reduction of the quality of the radio frequency link to the model.
󾻭Do not grasp the transmitter's antenna during ight. Doing so may degrade the quality of the radio
frequency transmission.
󾻫As with all radio frequency transmissions, the strongest area of signal transmission is from the sides of the
transmitter's antenna. As such, the antenna should not be pointed directly at the model. If your ying style
creates this situation, easily move the antenna to correct this situation.
󾻭Don’t y in the rain! Water or moisture may enter the transmitter through the antenna or stick openings
and cause erratic operation or loss of control. If you must y in wet weather during a contest, be sure to
cover your transmitter with a plastic bag or waterproof barrier. Never y if lightning is expected.
