ETHOS Operating System
Create the model
Step 1: First go to System Settings, then click Model Select to select
the model type.
Step 2: Configure the model channel and create the model name.
Model Setup Procedure-Internal Module
Step 1:
Touch the screen or use the navigation keys to enter the RF system menu.
Choose the INT MODULE. Then turn ON INTERNAL RF, select the OUTSIDE or INSIDE
ANTENNA. Set the Mode for TANDEM X18 internal RF corresponding to your
receiver (ACCESS, ACCST D16).
Step 2: Set the Channel Range
The TANDEM RF module supports 24 channels, the channel range is configurable,
and it needs to be double checked before use.
Step 3: Set the Receiver Number
The system will assign you the receiver a number automatically, when you
create a new model, and this can be easily changed. The range of the Model ID
is 00-63, with the default number being 01. Once the receiver is set to the
desired number and is bound to the TANDEM X18, the bind procedure will not
need to be repeated unless the receiver number is changed. At this point, set
the receiving number to your preferred number and repeat the binding operation
Step 4 : Registration
In ACCESS model, select the STATE [Register] into Registration status on radio
side. Then Press the F/S button
and power on your receiver, and select the “RX Name XX” and [REGISTER] to
complete the Registration process then power down the receiver.
Step 5: Automatic binding (Smart Match )
Move the cursor to Rx1[BIND],and select it, power your receiver, select the
RX, and complete the process, the
system will confirm “Bind succeed”. (Pressing the “F/S” button is not required
in ACCESS to Bind. Please refer to the receivers manual for details).
Step 6: Set Failsafe mode
There are 3 failsafe modes when enable: No Pulse, Hold, Custom
- No Pulse: on loss of signal the receiver produces no pulses on any channel. To use this type, select it in the menu and wait 9 seconds for the failsafe to take effect.
- Hold: the receiver continues to output the last positions before signal was lost. To use this type, select it in the menu and wait 9 seconds for the failsafe to take effect.
- Custom: pre-set to required positions on lost signal. Move the cursor to the failsafe mode of channel and press Encoder, then choose the Custom mode. Move the cursor to the channel you want to set failsafe on, and press Encoder.
Then rotate the Encoder to set your failsafe for each channel and short press Encoder to finish the setting. Wait 9 seconds before the failsafe takes effect.
Notice:
- When failsafe is disabled on TANDEM X18 side, the failsafe set on receiver side will be used.
- SBUS/F.Port/FBUS port does not support the No Pulse failsafe mode and always outputs. Set “Hold” or “Custom” for SBUS port.
Step 7: Range
Range refers to TANDEM X18 range check mode. A pre-flight range check should
be done before each flying session. Move the cursor to “Set”, scroll the
Encoder to select “RANGE” mode and press Encoder. In range check mode, the
effective distance will be decreased to 1/30. Press the Encoder again, turn to
normal state.
Model Setup for TANDEM X18 External RF Module
The external RF module can be powered on or off by software. The setup process
is the same as that for the internal RF. External modules should be closed
when not in use.

FLYING SAFETY
Warning
To ensure the safety of yourself and others, please observe the following
precautions.
Have regular maintenance performed. Although your TANDEM X18 protects the
model memories with non volatile EEPROM memory (which does not require
periodic replacement) and of a battery, it still should have regular check-ups
for wear and tear. We recommend sending your system to your Foskey Service
Center annually during your non-flying-season for a complete check-up and
service.
Battery
Using a fully charged battery (DC 6.5~8.4V). A low battery will soon die,
causing loss of control and a crash. When
you begin your flying session, reset your transmitter’s built-in timer, and
during the session pay attention to the
duration of usage. Also, if your model used a separate receiver battery, make
sure it is fully charged before each flying session.
Stop flying long before your batteries become over discharged. Do not rely on your radio’s low battery warning systems, intended only as a precaution, to tell you when to recharge. Always check your transmitter and receiver batteries prior to each flight.
Where to Fly
We recommend that you fly at a recognized model airplane flying field. You can
find model clubs and fields by asking your nearest hobby dealer.
Always pay particular attention to the flying field’s rules, as well as the presence and location of spectators, the wind direction, and any obstacles on the field. Be very careful flying in areas near power lines, tall buildings, or communication facilities as there may be radio interference in their vicinity
At the flying field
To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:
- Pull throttle stick to idle position, or otherwise disarm your motor/engine.
- Turn on the transmitter power and allow your transmitter to reach its home screen.
- Confirm the proper model memory has been selected.
- Turn on your receiver power.
- Test all controls. If a servo operates abnormally, don’t attempt to fly until you determine the cause of the problem.
- Start your engine.
- Complete a full range check.
- After flying, bring the throttle stick to idle position, engage any kill switches or otherwise disarm your motor/engine.
If you do not turn on your system on and off in this order, you may damage your servos or control surfaces, flood your engine, or in the case of electric-powered or gasoline-powered models, the engine may unexpectedly turn on and cause a severe injury.
Make sure your transmitter can’t tip it over. If it is knocked over, the throttle stick may be accidentally moved, causing the engine to speed up. Also, damage to your transmitter may occur.
In order to maintain complete control of your aircraft it is important that it remains visible at all times. Flying behind large objects such as buildings, grain bins, etc. must be avoided. Doing so may interrupt the radio frequency link to the model, resulting in loss of control.
Do not grasp the transmitter’s antenna during flight. Doing so may degrade the quality of the radio frequency transmission and could result in loss of control.
As with all radio frequency transmissions, the strongest area of signal transmission is from the sides of the transmitter’s antenna. As such, the antenna should not be pointed directly at the model. If your flying style creates this situation, easily move the antenna to correct this situation.
Don’t fly in the rain! Water or moisture may enter the transmitter through the antenna or stick openings and cause erratic operation or loss of control. If you must fly in wet weather during a contest, be sure to cover your transmitter with a plastic bag or waterproof barrier. Never fly if lightning is expected.
