Arcus E 2.2 ARF No. 2568

Dear customer,
Congratulations on your choice of a model aircraft from the robe  Modell sport range. Many thanks for placing your trust in us.
The model can be ready for the air when you have completed just a few simple procedures. Please read right through these instructions and the separate information sheets before attempting to assemble and fly the model, as this will  make it much easier to complete the tasks required.
Please study the illustrations and the brief instructions to obtain a clear understanding of the individual stages of construction.
All directions, such as “right-hand”, are as seen from the tail of the model, looking forward.
We constantly strive to update our products to reflect the latest developments. You can find details of technical improvements and revised documentation on the Internet by calling up the appropriate product description at our website:
www.robbe.com.
The full-size
The self-launching Arcus E is the first two-seat electric-powered glider to enter series production.
The model
Our model of the Arcus E closes the gap between moulded EPO foam gliders intended for beginners and the larger scale gliders of wood or GRP construction.
The Arcus E 2.2 gives the advanced model glider pilot the opportunity to exploit the numerous technical features of large models – such as retractable power unit, airbrakes and retractable wheel – in a low-cost model. At the same time this elegant scale glider retains the advantage of the robust EPO foam wing and  fuselage.

Radio control system
For this model you require a radio control system with at least six channels. We particularly recommend 2.4 GHz systems. The receiving system is powered by the speed controller’s integral BEC system.
Before you check the model’s working systems, set the control surfaces to neutral from the transmitter (transmitter sticks and trims central). When you wish to fly the model always move the throttle stick to the “motor stopped” position before switching the transmitter on. Only then connect the battery.
To switch off, first disconnect the flight pack from the speed controller, and only then switch the transmitter off.
When installing or setting up the receiving system components, including the speed controller, be sure to read and observe the instructions supplied with them.
Colour scheme
No painting is required.
Power system
A brushless out runner motor is factory-installed. The propeller is already fitted. The motor is connected to the speed controller, ready for use, and the controller is correctly set up at the factory. Prior to flying the model all you have to do is connect the Lipoid flight battery and the receiver, and check the servo travels – especially the end-points – for the model’s various auxiliary working systems.
Read right through the safety notes for the Lipoid battery, and the instructions supplied with the battery charger, before using these items for the first time.

– Wiring diagram for control functions, retractable power unit, airbrakes and retractable undercarriage (the stated channel assignment is correct for robe Futaba receivers)

1. Connect the servos to the receiver.
2. Connect the mixer to the speed controller.

Checking the working systems:

Motor and retractable power unit:
The model is fitted with a retractable power unit. The power unit extends from the fuselage for the powered phase of flight, allowing the model to climb to height.
The motor and the retractable power unit are controlled by the mixer fitted to the model.
The mixer module is connected between the speed controller, the retractable power unit servo and the receiver. 1.2 Checking the retractable power unit:
Move the throttle stick to the Idle end-point, then switch the transmitter on.
Locate the switch (channel 7) for the folding motor auxiliary function, and set it to NORMAL.
Connect the flight battery: the LED on the mixer starts to light up, and the power unit extends.
The speed controller emits a beep to indicate that it is switching to operating mode.
The LED on the mixer flashes if the throttle function is not at the Idle end- point, or if the trim is not at 24%.

1. Fig. 11 – 1.1 Retractable power unit mixer module:
   Typical settings, using a Futaba RC system as an example:
   – Complete the basic settings – such as mode, switch assignment etc. – as described in the instructions supplied with your RC system.
   – Set channel 3 to servo reverse.
   – Set the throttle stick to Motor Off, and the trim to +24%.
   1.3 Normal mode operation:
   The motor starts running when the throttle stick is advanced.
   The retractable power unit remains extended.
   1.4 Auto mode operation:
   Move the throttle stick to the Idle end-point, then move the auxiliary function switch to the Auto position.
   If you now slowly move the throttle stick to the “advance throttle” position, the power unit extends and the motor starts running. Moving the throttle stick back to the Idle position causes the motor to switch off, and the propeller is braked by the stopper.
   Note: on the ground, without any airflow over the propeller, you may find that the propeller does not stop in the correct position. In this case set the propeller to the vertical position with a screwdriver. The  power unit retracts after a delay of three seconds.
   If the motor fails to extend to the correct position, adjust the trim pots on the mixer module.
   – Reverse the direction of rotation of the auxiliary channel for the retractable undercarriage.
   – Connect the speed controller, the retractable power unit servo and the receiver to the mixer; the diagram shows the appropriate sockets.
   – Install the mixer module in the fuselage again.

2. Retractable undercarriage and airbrakes:
   The undercarriage is operated using channel 5. Check the end-points of the retract servo, and adjust the servo travel if necessary.
   The airbrakes are controlled by channel 6. Once again, adjust the end-points if necessary. 2.1 Centre of Gravity:
   Fix the battery in the fuselage in the appropriate position (Fig.12). Do not connect the battery at this stage. Install the wings and the tail plane.

Fig. 13
Control surface travels

Test-flying
Ensure that all the control surfaces are at neutral (centre), and check their direction of travel (sense).
The Centre of Gravity should not deviate from the stated point by more than 5 mm.
Wait for a day with little wind for the initial test-flights. The wind speed should not exceed 10 km/hr.
The Arcus E 2.2 is equipped with airbrakes which are used to reduce the model’s speed.
Check the effect of the airbrakes at a safe height with the motor switched off before using them on the landing approach.
Checking the working systems, setting up the control surfaces
– Charge the flight battery.
– Switch the transmitter on, and move the throttle stick to the “motor off” end-point.
– Give the flight battery a full charge, apply Velcro (hook and-loop) tape to the pack, place it in the fuselage, and connect it. Wait for the speed controller to emit a series of beeps.
– Place the canopy on the model.
– Check the channel assignment of the control surfaces, and swap over the connectors at the receiver if necessary.
– Check the neutral position of the control surfaces. If necessary, loosen the clamping screws in the pushrod connectors, set the control surfaces to centre, then re-tighten the screws.
– Check the direction of rotation of the servos.
– When you move the aileron stick to the right (a), the righthand aileron (a) should rise, the left-hand aileron (b) fall.
– Pull the elevator stick back towards you (c), and the rear edge of both elevators should rise (c).
– If any of the control surface functions works the wrong way round, correct it using your transmitter’s servo reverse facility for that channel.
– Check that all the linkages are firmly fixed, but free-moving.
– Check in particular that the clamping screws in the swivel pushrod connectors are properly tight.
– The travels are measured at the inboard end of the control surfaces.
– The stated control travels are just a guide for the first few flights. The final settings should be selected to suit the individual pilot’s flying style.
– The Expo settings should also be adjusted to suit the pilot’s preference.

Flying notes

• Read the sections in the Safety Notes entitled “Routine pre-flight checks” and “Flying the model” before attempting to fly the aero plane for the first time.
• For your initial test-flights please wait for a day with no more than a gentle breeze.
• A good flying site consists of a large, flat, open grassy field, devoid of obstacles such as trees, fences, high-tension overhead cables etc.
• Repeat the check of all the working systems.
• Ask an experienced modelling friend to hand-launch the aircraft for you. He should be capable of giving the aero plane a reasonably strong, flat launch.
• The model must always be launched directly into any wind.
• With the motor running at full-throttle, give the aero plane a firm launch directly into any breeze, with the fuselage and wings level.
• Keep the Arcus E flying straight and level at first; don’t initiate a turn while it is still close to the ground.
• Adjust the control surface trims if necessary, so that the model flies straight with a reasonable rate of climb “hands off”.
• Check the model’s response to control commands. You may need to increase or reduce the control surface travels after the first landing.
• Check the glider’s stalling speed at a safe height.
• Keep the model’s speed well above the stall  for the landing approach.
• Always switch off the motor before the model touches down.
• If you needed to adjust the trims during the test-flight, correct the length of the appropriate pushrod once the model is back on the ground,  then return the transmitter trims to centre so that full trim travel is available to both sides of neutral for subsequent flights.

Specification – 20 A speed controller:

Caution: the speed controller is not protected against reverse polarity. Connecting a battery to the controller’s terminals with reversed polarity will instantly ruin the unit.
VERY IMPORTANT: since different transmitters feature different throttle settings, we strongly advise you to use the “Throttle range set-up function” to calibrate the throttle range.
Setting the Full-Throttle and Stop positions:
(if the transmitter is new, the throttle range should always be calibrated)
Switch transmitter on, move throttle stick to full-throttle position.
Connect battery to speed controller.
You will hear the special beep sequence “123”. This means that the battery voltage is in the green zone.
This is followed by two longer beeps which confirm that the controller has correctly read in the upper limit of the throttle range.
The throttle stick must be moved to your preferred Stop position with two seconds; this is confirmed with a long beep.
This set-up procedure is concluded with an audible signal which indicates the brake setting.
(1 x short beep = brake off; 2 x short beep = brake on).
The speed controller is now ready for use.
NOTE:
If you do not move the throttle stick during the set-up phase, the motor will not run. In this case you must repeat the procedure. Using the controller for the first time:
Move the throttle stick to the Stop position, then switch the transmitter on.
Connect the flight battery to the speed controller:
you will hear the special sound sequence “123”, followed by a longer beep and the selected brake setting.
The speed controller is now ready for use.
Protective functions

1. Start-up guard: if the motor does not start within two seconds of the throttle command, the speed controller switches off the output voltage. If this should happen, you MUST move the throttle stick fully back before the motor will start. Failure to start may be due to any of the following reasons: the connection between speed controller and motor is intermittent; the propeller or the motor is jammed; the gearbox is damaged, etc.
2. Overheating guard: if the controller’s temperature rises above 110°C, the unit reduces the output voltage.
3. Throttle signal failure protection: if the throttle signal is absent for one second, the controller reduces the output voltage. If a further failure occurs for two seconds, the controller switches off the output voltage completely.

Description of functions

The speed controller is set up at the factory to suit the Arcus E 2.2.
