3. INITIAL STEPS a) Installation notes The four mounting holes in the base plate of the PowerBox Royal SRS are fitted with rubber grommets as standard. The Royal SRS should be mounted on a surface which is not subject to serious vibration, using the retaining screws supplied in the set. Although all PowerBox products are designed to be highly resistant to vibration, you should still avoid attaching the backer to thin GRP or CFRP surfaces.
c) Setting the receiving system to be used The first requirement is to define the receiving system. If this setting is not selected, the subsequent functions, settings and assistants only work in a restricted manner. Switch the PowerBox on as described above. Hold the SET Button pressed in for a few seconds, and the menu system appears.
Jeti Duplex: Connect two R-Sat2 satellites or REX receivers directly to RX1 and RX2. The receivers are bound in two-way mode. The following settings must be carried out: - Serial output: UDI Primary settings: - Signal speed: 10 ms - PPM settings: Direct - Failsafe: Inactive (if two receivers are in use; otherwise any setting) Visit us in our support forum for more and more detailed information how to connect receivers.
f) Channel assignment, output side As already mentioned, the outputs of the PowerBox Royal SRS can be assigned in any way, without restriction. This means that particular functions or channels can be assigned to any of the 24 outputs. The menu point where this is carried out is entitled OUTPUT MAPPING: This menu displays a graphic image of the outputs. You can use the cursor to move through the outputs in order to select the one you wish to assign.
The following set-up facilities are provided: - FUNCTION: » DIRECT 1…18: Depending on your radio control system, you can output channels 1 – 18 (Futaba) directly, i.e. as they arrive from the transmitter. Example: the right-hand landing flap is programmed to channel 9 at your transmitter, and you want to connect the landing flap servo to output D. Move the cursor to the OUTPUT D field, and confirm your choice with the SET button. Set DIRECT 9 under FUNCTION.
Default output assignments: Note: - After a Reset the fields outlined in green are assigned as shown below: - Fields outlined in red are assigned as shown below, but only if the Sequencer Assistant has been used: A Direct 5 / VALVE sequencer M free B R.H. wheel door N Direct 10 C L.H.
Before you carry out the fine-tuning flight we strongly recommend that you run through the TESTFLY ASSISTANT on the ground several times, to familiarise yourself with the sequence of operations and the way it works. It is also extremely helpful to have a fellow-modeller by your side during the set-up flight, as he will be able to follow the flow-chart, and keep track of the adjustment sequence.
The next step is to define the input channels: the Assistant automatically detects the channels when you operate them at the transmitter. Move the three-position switch on your transmitter. The Assistant does not accept your chosen switch until you have selected all three flight modes. Press the SET button when you have made your choice. Here again all you have to do is move the slider or rotary knob in order to inform the iGyro of the gain channel.
Now move the rudder stick. In this case the Assistant should only detect two channels if two gyro channels are used to control two separate rudders. Select your transmitter’s Servo Monitor to check the setting. Press the SET button when you have made your choice. This message instructs you to move to the next screen display and assign the outputs. Press the SET button twice when you have made your choice.
At this point you are requested to swing the model’s tail to left or right: the rudder should immediately deflect in response to this movement. Here again: if the rudder does not respond, briefly jerk the model’s tail once to left or right, so that the sensor switches to the correct axis. Now hold the model’s tail far enough to left or right to cause the bar to move to full deflection, and wait until the rudder jumps back to the neutral position. This concludes the procedure.
Testfly Assistant Another reminder at this point: please run through this Assistant several times on the ground to ensure that you are familiar with the sequence of operations. We have included small tick-boxes next to each individual step. If you have a friend to help you during the flying stage, he can tick the corresponding box when each stage is completed. If you are not absolutely sure of the status of the Assistant, there is no reason why you should not land the model, check, then fly again.
The iGyro now again waits until you switch back to FM2 or FM3, and the gain adjuster is returned to 0%. once those requirements are met, gyro gain for elevator can be adjusted in flight. Again fly the model straight and level, and carry out a slow pass. Advance the gain adjuster until the model just starts to oscillate around the elevator (pitch) axis, then reduce the gain setting slightly. If you wish, you can fly several circuits to check that the setting is correct.
The iGyro now waits again until you switch back to FM2 or FM3, and the gain adjuster is returned to 0%. The next step rudder gain in Heading mode can be adjusted once those requirements are met. The procedure for setting rudder gain in Heading mode is identical to the preceding method. However, if you are not satisfied with the setting after the first pass, initiate a turn using very gentle rudder in addition to aileron, as this suppresses Heading mode for rudder.
h) Using the Door Sequencer Assistant The Setup Assistant significantly simplifies the set-up procedure for the door sequencer function. The Setup Assistant is not a second door sequencer; instead its purpose is to define the Tasks in the door sequencer to match your requirements, i.e. the information you enter. Because of this it is also possible at any time to expand or alter the retract or wheel door functions after you have completed the Setup Assistant procedure.
The purpose of this menu is to set up the way the door sequencer operates.
The undercarriage should now retract. If not, hold button I pressed in until the valve is triggered, and the undercarriage retracts. Press the SET button to move on to the next stage of the procedure. Connect the nosewheel door servo to output F. Press the SET button to close the nosewheel door; repeat the procedure in the next set-up screen to open the door. In the next series of steps the second nosewheel door and the rear wheel doors are set up.
4. SERVO-MATCH FUNCTION The Servo-Match function provides the facility for adjusting the centre position and end-points of the servos connected to the backer. If you have a model aircraft with more than one servo per control surface, this makes it possible to set up multiple servos to move to identical positions at identical times.
The following examples illustrate the correct procedure for the Servo-Match function: a) Fine-tuning multiple servos to operate on a single control surface (in this case the aileron of the right-hand wing) - Disconnect the linkages to the - as yet unmatched - servos, to avoid them being subjected to severe forces during the adjustment procedure. - Assign multiple outputs to the appropriate socket in the OUTPUT MAPPING menu. In this example: output G and output H - GY-AILERON A.
- Now set the appropriate end-point using button I or II before concluding the procedure with the SET button. - Move the transmitter switch to the “retracted” position, then press the SET button again. - Now set the corresponding end-point with button I or II, and conclude the procedure by pressing the SET button. - Both landing flaps will now move synchronously. 5. CHANNEL ASSIGNMENT, INPUT SIDE Modern SRS bus technology makes it possible to assign any channel to any function without restriction.
Procedure for setting up the Fail-Safe function: access the OUTPUT MAPPING menu and set the appropriate outputs to fail-safe as shown above. Now leave the OUTPUT MAPPING menu and select the RX/TX Settings menu, where you will find the TEACH FAILSAFE POSITIONS menu point.
As can be seen from the diagram, gyro gain is suppressed proportionally with increasing stick travel. This reduces the tendency for the iGyro to counteract intentional control commands. b) Speed-dependent gain control The PowerBox Royal SRS can be connected to an optional GPS sensor with the purpose of passing speed data to the gyro. The GPS Sensor supplies data regarding the model’s speed to the iGyro at a rate of twice per second.
mode switch is only needed in order to switch Heading mode on and off for the rudder. In the case of the rudder, Heading mode is only required for particular manoeuvres - such as slow rolls and knife-edge flight - and should be switched off again after the manoeuvre by changing the Flight Mode. When a model is negotiating a normal turn, Heading mode for the rudder has an unwanted effect, because the model’s tail tries to maintain the aircraft’s previous direction, and counteracts the pilot’s commands.
The model must initially be trimmed without the iGyro, or with the iGyro switched off, and must be set up to fly straight and level. If you subsequently make adjustments to the model’s trim, you will need to re-start the set-up procedure, or carry out a zero calibration of the iGyro. This action teaches the iGyro a new centre, so that the Heading mode can work properly. More on this later. At least one channel is required for setting gyro gain in flight.
Note: if your model features other superimposed functions - such as camber-changing flaps and ailerons - then you should be aware that the iGyro will not operate in Heading mode when the flaps are deployed. In this case the gyro system only operates in Normal mode, since the transmitter control is no longer at the centre position which the system “learned” when it was switched on. The direction of gyro effect is of no importance when the gyro is switched off. Test-fly the model now in Flight Mode 1, i.e.
up, the left aileron down. If the control surfaces respond in the opposite direction, you must reverse the direction of gyro effect by setting the DIRECTION point to REVERSE. Ensure that both ailerons move in the correct direction; if your model has two aileron channels, AILERON-B must also be set correctly.
VIII) After the flight there are two possible methods of disabling the assigned gain adjusters: 1) Access the GYRO SETTINGS menu, briefly select the two menu points GAIN NORMAL and GAIN HEADING using the SET button, then release the button again. If you have two separate aileron channels, repeat this procedure for AILERON-A and AILERON-B. 2) Access the INPUT MAPPING menu, and set the assignment for NORMAL GAIN and HEADING GAIN to 0 using the SensorSwitch.
With the model on the ground, select the GYRO SETTINGS menu and enter the values manually. After the flight the menu will look approximately like this - but naturally with the gain values which you have found to be correct during your test-flight: Disable the gain adjuster for Normal mode by moving the cursor to GAIN NORMAL, and pressing the SET button twice. Use the SensorSwitch to set the GAIN HEADING value for flight mode 2 to 0%.
h) Boost The default value for this function is 0. It ranks as one of the iGyro’s “expert functions”, and its basic purpose is to provide better stabilisation for models which are very unresponsive. In extremely windy conditions this function may also provide a better corrective effect. The fundamental effect of the iGyro’s Boost function is to produce a brief but very pronounced compensatory action right at the onset of any external influence.
8. MANUAL DOOR SEQUENCER INSTALLATION Select the DOORSEQUENCER point in the Main menu, and you will see this screen display: The PowerBox door sequencer is an in-house development which offers unprecedented facilities for the programmed movement of wheel doors. Right at the outset it is important to understand that the system opens up entirely new possibilities.
Intelligent programming aid: If you wish to set up multiple tasks in order to move the wheel doors to several positions, it should be obvious that the new task’s initial positional value and start time are determined by the previous position and time for the servo concerned. This is carried out automatically, helping to speed up the programming procedure, and eliminates the need for you to note down the servo’s previous position and stop time.
Note: if you wish simply to switch servos or valves on or off, you must always enter a time difference in the sequence, as the door sequencer needs a small amount of time to carry out its calculations. The following is an example for a retract valve: The time lag of 0.1 s is sufficient, and is virtually unnoticeable in practice. Important: the first START POSITION at UP » DOWN must always coincide exactly with the last STOP POSITION of DOWN » UP.
However, until now there has always been one drawback: if a short-circuit occurs in one servo, this blocks the bus lead, and all the servos connected to it stop working.
12. RESET, UPDATE, SAVE AND RESTORE The Royal SRS offers numerous facilities for resetting individual ranges without affecting other settings. For example, it is possible to reset Output Mapping without affecting the iGyro settings. All the Reset options can be found in the RESET/UPDATE menu: In the interests of safety, the software generates a confirmation query when you select one of the Reset options; the intention is to avoid accidental erasure of data.
