SPEKTRUM DX8 • RADIO INSTRUCTION MANUAL

Move the programmed master channel while observing the slave channel. The
slave channel should move accordingly.

Offset

The Offset function establishes the point at which the two mix rates converge.
Typically, this rate is center or 0%. If an offset is needed (normally not in a
helicopter), do the following.

Programming an Offset

Rotate the roller to highlight Offset then press. Rotate the roller to adjust the value.
Po and negative - values shift the offset in either direction. Press the roller
to accept.

Trim Include

The trim include function applies trim to the slave channel when the selected
master channel has trim (throttle, aileron, elevator and rudder). Typically this
is used when more than one channel operates a primary control surface (dual
aileron servos, etc.) With trim include activated, the master channel’s trim affects
the slave channel’s trim as well.

Activating Trim Include

Rotate the roller to highlight Trim then press. Press the roller to toggle between
INH and ACT.

GYRO

Use the Gyro function to program and adjust gyro gain. You can program up to
four gyro gain values to be selected from a variety of switches including the flight
mode switch. You can adjust gyro gain values in .5% increments allowing for
precise gain adjustments. Also, you can program the channel the gyro gain is
controlling. The DX8 displays gyro gain values as N for Normal gain and a T for
tail lock (heading hold). The percentage values are the true gain values in each
mode.

To Activate the Gyro Gain Function

With the transmitter on and the main or telemetry screen displayed, press the
roller. The Function list displays.

Rotate the roller to highlight Gyro then press to access that screen.

To Select a Switch

The Gyro function defaults to Inhibit. To activate the Gyro function, highlight
Inhibit, then press the roller to access the switch function. Rotate the roller to
access the desired gyro control switch. Press the roller to access the Gyro gain
screen.

Assigning a Channel- (Output)

You can assign the receiver channel the gyro gain is plugged into in this screen.
The governor and the gyro must use two different channels. A channel used by
the governor function does not appear in the Gyro list.
Highlight Ch: (channel) then press to access the gyro channel function. Select the
desired channel to plug the gyro gain into, normally the Gear channel is used.

Adjusting the Rate values

Rotate the roller to select the desired gain value then press. Select the gain value.
Any time a T displays, the gyro is in tail lock (Heading Lock). If an N displays, the
gyro is in normal mode.

Repeat this for all desired gain values.

TIMER

The DX8 Timer function allows you to program a Count Down timer or Stop
Watch (count up timer) to display on the main screen. An alarm sounds when
the programmed time is reached. You can program the timer to start using the
trainer switch, the left or right trimmers or automatically when throttle is raised
above a preprogrammed position. Also, an internal timer that shows run time for
a specific model displays on the main screen.

To Access the Timer Screen

With the transmitter on and the main or telemetry screen displayed, press the
roller. The Function list displays.
Rotate the roller to highlight Timer then press.
