DETRUM GY48V Instruction Manual

GY48V is a gyro with dual rate and head lock function, which is designed for helicopters planes&cars especially.
GY48V adopts AVCS (Angular Vector Control System ), which makes the function lock more outstanding and steady.
AVCS system: since rudder trim changes caused by wind and other meteorological changes, and varieties of the helicopter
attitude changes are automatically cancelled, tail rudder operation becomes easy, making it perfect for 3D flight.

GY48V specification:

Digital proportional R/C system
Dimensions(mm): 28*28*20
Operating voltage: 4.8V ~ 6V
Operating temperature:-10°c~ +45°c
Operating current: 80mA

Functions:

Minimizes changes in an aircraft's attitude by wind etc.
Angular acceleration commands used.
Sensor vibration proofing.
Simple sensitivity adjustment.

Digital servo mode switch. When using a digital servo, please set the switch to the on position. While using the normal one, set it to the off
position, the servo will be destroyed.
Switch control direction of the gyro, it must be switched correctly according to the rotation direction of the main rotor on the helicopter and the
direction of the rudder linkage.
Adjust operation speed of rudder control signal. If using slower speed rudder, please turn the knob clockwise to increase delay time, then you
can stop tracing. If using high speed digital servo, please turn the knob anticlockwise to the position of "0" .
Adjust operation speed of rudder control signal. If using slower speed rudder, please turn the knob clockwise to increase delay time, then you
can stop tracing. If using high speed digital servo, please turn the knob anticlockwise to the position of "60
Connect to the receiver rudder channel(CH4)
Connect to the receiver sensitivity switching channel(normally Ch5). This connector can be simultancously used to switch the sensitivity of
gyro between the AVCS and normal modes. Since this connector is a single line, do not pull it forcefully.
Connect to the rudder servo.

Gyro operation state
Indicate that data is being initialized after you turn
on the power.
Indicate that the gyro is operating in the AVCS mode.
Indicate that the power is off, or the gyro is operating
in the normal mode.
Indicate that the gyro has not received any signal of
rudder operation from the transmitter, the rudder
servo cannot operate at this time.
Indicate that open power in the normal mode, but gyro
can't initialize the data correctly at that time, please
switch the gyro sensitivity switch to the AVCS mode,
and close the power of transmitter, then open it again,
when in AVCS mode, rudder control signal currently
received is different from neutral signal in the gyro.
It happens in the following circumstances:
the rudder stick is operating,
the neutral position of tail rudder is moving,
and you have to readjust and set it.
