Operation in AVCS mode

If the rudder stick is operated or the helicopter is moved when the

helicopter was stopped during operation in the AVCS mode, the servo

will not return to the neutral position even if the rudder stick is re-

turned to the neutral position, and when the rudder stick is moved, the

rudder servo controls operation until the tail reaches the maximum

point. This is caused by addition of an integration function as an

AVCS mode operation and is not an abnormality. In actual ight, the

gyro constantly monitors movement of the tail and controls the servo

so that movement of the tail is stopped.

AVCS mode servo neutral position check method;

If the rudder stick or the helicopter was moved in the AVCS mode, the servo

will not return to its original neutral position. When the power is turned on,

the servo will return to the neutral position. The servo neutral position can

also be checked by the following method.

Neutral

position

Move the rudder stick 3 times to its full stroke to the left

and check method right at an internal of within 1 second

and immediately return the rudder stick to the neutral

position. The servo moves to the neutral position about 1

second later.

NORMAL mode sends control signals to the rudder servo only

when the tail of the helicopter moves. When the tail stops mov-

ing, the control signal from the gyro becomes zero. Conversely,

the AVCS mode continues to send control signals to the servo

even when the tail of the helicopter stops moving. The following

sequentially describes the NORMAL mode and the AVCS mode.

Operation of NORMAL mode

Basic operation is described by considering the case when the

helicopter is hovering under cross-wind conditions. With a nor-

mal mode, when the helicopter encounters a cross-wind, the

force of the cross-wind causes the tail of the helicopter to drift.

When the tail drifts, the gyro generates a control signal that stops

the drift. When the tail stops drifting, the control signal from the

gyro becomes zero. If the cross-wind continues to cause the tail

to drift in this state, the "stop" operation is repeated until the tail

faces into the winds. This is called the "weathervane" effect.

Operation of AVCS mode

Conversely, with an AVCS mode, when the helicopter encoun-

ters a cross-wind and the tail drifts, a control signal from the gyro

stops the drift. At the same time, the gyro computes the drift an-

gle and constantly outputs a control signal that resists the cross-

wind. Therefore, drifting of the tail can be stopped even if the

cross-wind continues to effect the helicopter. In other words, the

gyro itself automatically corrects(auto trim) changes in helicopter

tail trim by cross-wind. Considering operation of an AVCS mode,

when the tail of the helicopter rotates, the servo also rotates in

accordance with the angle of rotation of the tail. When the tail

stops rotating, the servo judges that it has stopped in that posi-

tion. This is the auto trim function.

What is S.BUS?

Unlike conventional radio systems, the S.BUS system uses

data communication to transmit control signals from a

receiver to a servo, gyro, or other S.BUS compatible device.

This data includes commands such as “move the channel 3

servo to 15 degrees, move the channel 5 servo to 30 degrees”

to multiple devices. The S.BUS devices execute only those

commands for their own set channel. For this reason, it can

be used by connecting multiple servos to the same signal

line.

* Set the channel at the S.BUS servos by using an SBC-1 channel changer or a CIU-2 USB serial interface.

Can also be used together with conventional servos. However, conventional servos cannot be used by the S.BUS output.

When using servos with a remote battery pack, use S.BUS Hub with Cable (2-way/remote battery pack use).

Please refer to the instruction manual of S.BUS Hub with Cable (2-way/remote battery pack use) for the connection method.

󾛹

Please turn on the power supply of the transmitter rst without fail, and, next, turn on the receiver if you use

S.BUS

. Moreover, please use it

after it conrms the operation without fail. Otherwise, the

S.BUS

communication cannot be judged and it is likely to malfunction.

󾛹

The wiring for the

S. BUS

servo is replaced at power supply OFF. If you replace the wiring in power supply ON,

S. BUS

communications

cannot be judged, and it seems to malfunction.
