Spektrum DX8 Manual

Spektrum DX8 - DLG Setup in Sailplane mode

Sailplane mode has been made available since April 2013. If you have not updated their firmware,

please visit http: www.spektrumrc.com to get the firmware and setup instruction. This instruction set is

mainly used for setting up a Discus Launch Glider (DLG) with flaperons using a Spektrum DX8 on any

6ch receivers.

Note: Setup may differ according to each pilot's preference and below is a setup to start.

System Setup Page (switch x on with Roller Switch pressed down)

Switch Select Setup

The Trainer Bind button is on the left of the aerial. The Trainer Bind button will be used for my launch

preset. For the pushbutton to function as the preset, you need to assign them to an Aux. I assigned

Aux2.

Note: You need to set "Aux2:lnh” before you can set "Trainer: Aux2"

Flight Mode Setup

I only have 3 flight modes:

Launch

Cruise

Thermal

If this is the case, select "2 or 3 Flight Modes" and assign your preferred switch (I use F Mode)

Now the System Setup is completed. Press back button to exit Setup to Main Panel.

Set Reverse so that your servos travel in the direction you require

Dual rate (D/R) and Expo

The throws are adjusted based on feel. If you have unsteady thumbs use lots of Expo on all controls. Set

them according to your flying style.

Differential

UP Aileron is set to move more by proportion to the Down Aileron on the other side.

Set to On and vary the % to get the amount of Differential you need to avoid asymmetric Aileron

behaviour.

Camber Presets

Flight modes are pretty subjective. Some models have different preference. Different settings are used

on different models and you take time trimming these settings out on the field. In general, the starting

settings on this particular model are:

Launch mode - Reflex -1.5mm, elevator -0.75mm

Cruise mode - Camber 0mm, elevator 0mm

Thermal mode - Camber +2.5mm, elevator +1mm

Flight modes settings can be done in the "Camber Presets" page. Initial settings are shown in the photo

below. Do note that the Elev % numbers are adjusted at the field.

Launch Preset

At launch, to rotate the DLG up use some elevator up input using the bind button. Launch preset is setup

in the "Mixing" menu.

Select an available mix and assign AX2 to mix with ELE. The rate is adjusted at the field according to

your preference.

Reminder: The Aux2 button was assigned earlier (see Switch Select Setup). Air Brakes)

Air brakes are activated using the throttle stick (down position).

While in the Camber System page, position the flight mode switch at Launch position (position 0). Select

input as "Spoiler Stick". Position the throttle stick to where you want to activate the airbrakes. Adjust the

Aileron rates according to your preference.

Select Cruise mode using F-mode switch (position 1). Repeat adjustment similar to Launch mode

Select Thermal mode using F-mode switch (position 2). Repeat adjustment similar to Launch mode

Note: Offset settings depends how your aileron servo horns are mechanically setup. Adjust accordingly.

Do try playing around with the rates as it may differ from model to model.

Flap/Elevator Mix

After the flaperons have been setup, the elevator needs to compensate to prevent the DLG from

ballooning up when the air brakes are activated. In the Mixing menu, go into Flp>Ele mix to setup the

elevator compensation. The settings below should be good enough to start with final values should be

done at the field.
