Hobbywing Technology G3 Advance Gyro User Manual

User Manual of Gyro
【FEATURES】
1. This Gyro uses advanced MEMS (Micro Electro Mechanical Systems) angular rate
sensor and AVCS (Angular Vector Control System) algorithm. It is a super performance,
compact, light weight gyro developed for model helicopter.
2. Built-in temperature compensation provides high-precision direction control ability to
eliminate the drift caused by environment temperature changing.
3. Dual working mode: Normal Mode and Head-Lock Mode, switched by the sensitivity
value of the GAIN channel of your transmitter.
4. The program process is completely digitalized to make the gyro more reliable. Each
programmable value is adjusted by a "SET" button without any analog component such
as trimming potentiometer.
5. Compatible with standard (333Hz) and narrow band (560Hz) digital servos.
【SPECIFICATION】
1. Dimension: 26mm * 24mm * 9mm
2. Weight: 12g (wires and connectors included)
Operating voltage DC 4.5-6.5V, operating current ≈ 50mA, maximum current <100mA
3.
4. Servo: Standard digital servos (frequency 333Hz), servo neutral point: 1520us
Narrow band digital servos (frequency 560Hz), servo neutral point: 760us
This gyro cannot work with analog servo!
【WIRING】
1. Connect the rudder servo lead to the
female connector on the gyro.
2. There are 2 male leads coming from
the gyro, the lead with black, red
and white wires is plugged into the
Rudder channel of your receiver,
and the lead with one single orange
wire is plugged into the Gain
channel of your receiver.
For Futaba receiver, Rudder
channel is located in channel 4 (CH4)
and Gain in channel 5 (CH5).
For JR receiver, Rudder channel is located in channel 3 (CH3) and Gain channel in
AUX2.
For other remote control systems, please read their user manuals for reference.
【GYRO INSTALLATION】
Please install the gyro
close to the centre of
fuselage and keep
away from vibration.
Please don't install the
gyro close to heat
generation sources, or
strong electromagnetic
interference sources, or high vibration sources such as motor, speed controller, etc.
VER: HW-100-G3 ADV-20111228
To isolate the vibration to the gyro, a soft foam pad should be attached on the bottom of the
gyro. If helicopter tail drifts during flight, please check the vibration source of fuselage and
install the metal plate (package included) for high frequency vibration isolation purpose.
【SPECIAL HINTS FOR INSTALLATION ON NITRO-POWERED HELICOPTER】
Please Install and handle with care. If tail drifts, please use the following methods for trouble
shooting.
1. Install the steel plate, and try difference thickness of foam tape pads. In general, using
thinner foam pads can provide better performance.
2. Carefully fasten the gyro wires to avoid extra vibrations affect gyro performance.
3. After the above operations, run the engine under idle speed and touch the gyro case to
test vibration. If no obvious vibration conducted to gyro, which means the installation is
successful.
【START TO USE】
1. Turn on transmitter and ensure the output
signal is in good condition.
2. Set the GAIN value above
transmitter to select Head-Lock Mode.
3. Keep the rudder stick at neutral position,
and then power on the gyro (That means
connecting the battery pack to the speed
controller to supply the receiver, then the
gyro gets its power supply from the receiver).
Don't move the rudder stick or the helicopter
until the initialization process is completed.
Gyro cannot work properly if it is not initialized with Head-Lock Mode.
4. Some old transmitters (such as Futaba FF7S, FF6S and T6XHS, etc) haven't the gyro
sensitivity switching function, in such
a case, the gyro sensitivity setting is
performed by adjusting the ATV of
the GAIN channel, and the mode
switching of Head-Lock Mode and
Normal Mode is performed by the
switch position.
The figure is an example
sensitivity setting with a T6XHS
transmitter. In the hovering flight,
(That is: Head-Lock Mode), the gyro
sensitivity is set to 72%, and in the
Idle-up flight (That is: Normal Mode),
the gyro sensitivity is set to 54%.
The Head-Lock Mode and Normal
Mode are switched by the CH5 switch position.
Please always keep in mind that when the sensitivity switching is performed with
the ATV setting, the Head-Lock Mode cannot be used at both side (that means forward
position and backward position) of the CH5 switch for hovering and Idle-up flight.
