Operating system ECOS

Creating a model

1. Open the Model select menu, select a free slot and follow to Create model.
2. Select the type of model.
3. Rename and configure the newly created model.

Model setting - internal RF module

Select the model, open the Edit model menu page 2/10. Switch on the internal RF module by switching the „Mode“ menu to the required protocol ACCESS or ACCST D16.

Channel range

The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model (CH1–8, CH1–16 or CH1–24). Further channel settings are located in the Outputs menu on page 5/10.

Receiver ID

The option RxNum automatically assigns the receiver ID upon activating the internal RF module. You can set the same ID for another model if the same receiver and receiver setup can be applied to that model. The RxNum can be set from 00 to 63, with the default being 00.

Registration and pairing

Before you can start using your transmitter, you must first register the desired receiver.

Protocol ACCESS

1. Begin the registration process by selecting [Reg] in the Module option.
2. A window will appear with the message "Waiting...."
3. Hold down the pairing button on the receiver and turn it on. Wait for the registration to complete
4. The Registration ID and User ID can be set at this stage.
5. You can choose a custom name for the receiver.
6. Press the [Enter] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
7. Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.

• Reg. ID: This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models, including receivers, between them using the Smart Share function.
• RX name: the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. RR6R1 is for CH1–8 or RX4R2 is for CH9–16 or RX4R3 is for CH17–24.
• UID: is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually 0 for CH1–8, 1 for CH9–16 and 2 for CH17–24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.

Caution: Do not pair with an electric motor connected or with a combustion engine running.

Binding Binding a receiver allows the receiver registered in phase 1 to be paired with the transmitters. The receiver will now communicate with this transmitter only unless you bind it with another transmitter.

1. Select a receiver slot and press [Bnd]
2. Turn on the receiver
3. The receiver will pop up.
4. Select the receiver and wait for the automatic binding to finish.

• The receiver will only be controlled by the transmitter it is bound to. Other transmitters in its vicinity will not affect its operation.
• The name of the receiver will now be displayed in the selected slot.
• The receiver is now ready for use.
• If a redundant connection is required, repeat for receiver slots 2 and 3.

Protocol ACCST D16

The ACCST D16 protocol doesn't use the registration system, only the pairing system.

1. Turn off the power to the receiver.
2. Fill in receiver ID, and press [Bnd]. A pop-up window will appear with a selection of channels. Select your preferred channel range to start the pairing process.
3. Turn on the receiver while holding the pairing button.
4. Select your receiver.
5. Switch off the transmitter and receiver.
6. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter.

• The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
• The name of the receiver will now be displayed in the selected slot.
• The receiver is now ready for use.

You don't have to repeat the pairing process unless the receiver is replaced.

Fail-safe emergency rates

When Fail-safe is enabled, 4 modes are available: Hold, Custom, No pulses and Receiver.

• Hold: the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
• Custom: the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.
• No pulses: when the signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
• Receiver: when the signal is lost, the fail-safe mode set in your receiver is applied.

Note: If the failsafe is not set, the model will always work with the last working status before the signal is lost. That could cause potential damage.

When the failsafe is disabled on the RF module side, the failsafe set on the receiver side will be applied.

S.BUS port does not support the failsafe setting in No Pulses mode and always outputs a signal. Always set "Hold" or "Custom" mode for the SBUS port.

Range check

A pre-flight range check should be performed before each flight, in case the signal loss is caused by the reflection of the signal by the nearby metal fence or concrete, and the shading of the signal by buildings or trees during the actual flight. Under normal circumstances, in Range Check mode, the RSSI at 150 m is about 45–50.

1. Place the model at least 60 cm above the ground on a non-metal surface (such as a wooden bench). The receiver's antenna should be in a vertical position.
2. Open the "Edit model" menu, then scroll to the "Module" section and press [Rng]. In Range Check mode, the effective transmission distance is decreased to 1/30.

Conclusion

Principles of safe operation

Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.

• Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
• Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.

• Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialisation processes are completed.
• Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
• Never fly in range check mode. In this mode, the transmitter operates at reduced power, and a crash could occur.
• Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
• Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
• If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
• Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
• For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
• Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
• Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
• At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
• Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
• Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
• When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.
