FUTABA 6k Instruction Manual page 10

Never fly on a rainy day, when the wind is
strong, and at night.
■ Water could lead to failure or improper functionality
and poor control of the aircraft which could lead to a
crash.
Never turn the power switch on and off during
flight or while the engine or motor is running.
■ Operation will become impossible and the aircraft will
crash. Even if the power switch is turned on, operation
will not begin until transmitter and receiver internal
processing is complete.
Do not start the engine or motor while wearing
the neck strap.
■ The neck strap may become entangled with the
rotating propeller, rotor, etc. and cause a serious injury.
Do not fly when you are physically impaired as
it could pose a safety hazard to yourself or others.
Do not fly at the following places:
■ Near another radio control flying field.
■ Near or above people.
■ Near homes, schools, hospitals or other places where
people congregate.
■ Near high voltage lines, high structures, or
communication facilities.
When setting the transmitter on the ground
during flight preparations, do not stand it upright.
■ The transmitter may tip over, the sticks may move and
the propeller or rotor may rotate unexpectedly and cause
injury.
Do not touch the engine, motor, or FET amp
during and immediately after use.
■ These items may become hot during use.
For safety, fly so that the aircraft is visible at all
times.
■ Flying behind buildings or other large structures
will not only cause you to lose sight of the aircraft, but
also degrade the RF link performance and cause loss of
control.
From the standpoint of safety, always set the
fail safe function.
■ In particular, normally set the throttle channel to idle.
For a helicopter, set the throttle channel to maintain a
hover.
When flying, always return the transmitter
setup screen to the Home screen.
■ Erroneous input during flight is extremely dangerous.

Always check the remaining capacity of the
transmitter and receiver batteries before each
flying session prior to flight.
■ Low battery capacity will cause loss of control and a
crash.
Always check operation of each control surface
and perform a range test before each flying
session. Also, when using the trainer function,
check the operation of both the teacher and
student transmitter.
■ Even one transmitter setting or aircraft abnormality
cause a crash.
Before turning on the transmitter:
1. Always move the transmitter throttle stick position to
the minimum (idle) position.
2. Turn on the transmitter first and then the receiver.
When turning off the transmitter's power
switch. After the engine or motor has stopped
(state in which it will not rotate again):
1. Turn off the receiver power switch.
2. Then turn off the transmitter power switch.
■ If the power switch is turned on/off in the opposite
order, the propeller may rotate unexpectedly and cause a
serious injury.
■ Also always observe the above order when setting the
fail safe function.
■ Maximum low throttle: Direction in which the engine
or motor runs at the slowest speed or stops.
When adjusting the transmitter, stop the
engine except when necessary. In the case of
a motor, disconnect the wiring and to allow it
to continue operation. When doing so, please
exercise extreme caution. Ensure that the aircraft
is secured and that it will not come into contact
with anything or anyone. Ensure that the motor
will not rotate prior to making any adjustments.
■ Unexpected high speed rotation of the engine may
cause a serious injury.
