PRECAUTIONS

󾾝WARNING

Failure to follow these safety precautions may

result in severe injury to yourself and others.

s2EADTHROUGHTHE ENTIRE MANUALBEFOREOPERAT-

ing this product.

BEFORE EACH FLIGHT:

￸Always check the transmitter and receiver bat-

tery voltage to ensure they have enough remain-

ing capacity to complete the ﬂight.

￸Always exit programming mode before at-

tempting to ﬂy the model.

￸Only use the CGY750 with a 2.4GHz system

such as the Futaba FASST™ system, or a PCM

system. Use with an FM system is strongly dis-

couraged since interference can cause serious

operational problems.

Gyro operating precautions:

Gyro

￺The CGY750 requires 5-10 seconds to ini-

tialize when the power is turned on. Do not

move the helicopter and do not move the tail

rotor, aileron and elevator sticks during this

initialization or the gyro may not initialize

properly. Once the initialization process has

been completed the swash servos and tail

servo will move several times indicating that

the CGY750 is now ready for ﬂight.

￸Verify that the gyros are operating and com-

pensating in the correct direction before each

ﬂight. If the compensation direction is incorrect

on any axis the model will become incontrollable

after take off.

￸Verify that the gyro is operating in the desired

mode.

PRECAUTIONS

￸Verify that the gyro mounting pads are in good

condition.

￸Verify that the gyro wires are not contacting

the frame of the helicopter.

￸The servo type parameters within the CGY750

must match the type of servo you are using. In-

correct setting may damage the CGY750 or the

servos, possibly resulting in a loss of control dur-

ing ﬂight.

￸Always ensure that there is some slack in

the gyro cables to help maximize performance.

Always use the supplied gyro mounting pads to

attach the gyro to the helicopter mechanics. Do

not use a strap that encompasses the CGY750

sensor. This may affect the overall performance of

the gyro.

￸Always allow the gyro to adjust to the sur-

rounding environmental temperature before ﬂight.

A large temperature change during use will cause

drift and other operational issues.

￺The gyro sensor and control box have a elec-

troconductive coating. Do not allow any power

leads or other wiring to come into contact with

these items.

￸If you are switching between Normal Mode

and AVCS Mode in flight, please keep in mind

that you must have the gyro re-learn the center

position after making a trim change within the

transmitter. To memorize the new center position

simply ﬂip the gain switch on the transmitter three

times between Normal Mode and AVCS Mode

(NormaltAVCStNormaltAVCS) within one

second. The servo will center indicating that the

new center position has been memorized.

￸When operating the gyro in AVCS Mode, all

compensation and revolution mixing must be dis-

PRECAUTIONS

abled and any tail rotor or swash offsets for ﬂight

modes must be disabled.

￸When the CGY750 is operated in AVCS mode

the tail rotor or swash servos will not center when

tail rotor, aileron or rudder stick is released. This

is normal operation for AVCS mode. The servos

may also move to the extent while the model is

being carried out to the ﬂight line. Before take off,

you must visually center the tail rotor pitch slider

and level the swash plate by using the transmitter

control sticks. You can also center the servos by

moving the tail rotor stick full left, then full right,

back to full left and then allow the stick to center

within one second; similarly for aileron and eleva-

tor servos.

￺Do not drop the CGY750 sensor onto a hard

surface or subject the CGY750 sensor to a strong

shock as this may damage the sensor.

￸Always use the supplied mounting pads or

the Futaba replacement mounting pads available

from your local hobby dealer.

Governor operating precautions:

Governor

￸When the throttle servo is connected to the

CGY750 the battery failsafe function within the

CGY750 must be setup and enabled.

￸Throttle fail safe function (transmitter setting):

Use the fail safe function for the channel that

turns the governor on and off to set the fail safe

position to the point at which the governor is

turned off. With this setting, when the system en-

ters the fail safe state, the governor will be turned

off and the receiver throttle signal (fail safe posi-

tion preset) will be output directly.

￸When using the condition hold function on the

PRECAUTIONS

transmitter, always set the throttle servo maxi-

mum operating point to less than the point at

which the governor is activated. If this is not done

the governor may activate while in condition hold.

￸While preparing for ﬂight or starting the engine

always ensure the throttle remains below the gov-

ernor activation point and do not select any ﬂight

modes that may activate the governor.

￸If you prefer to activate the governor while the

model is still on the ground always ensure that

you have at least -5 degrees of pitch in the model

before activating the governor. This is necessary

to prevent an unexpected lift off as the governor

activates and the head speed increases to the

DESIRED20-

￸0ERIODICALLY CHECK THE 20- SENSOR OUTPUT TO

ensure proper governor operation. Due to the

high level of vibration and centrifugal forces the

magnet may come loose or the sensor alignment

may change. Verify that the magnet and sensor

are properly mounted every 10th ﬂight.
