    3. INITIAL STEPS a) Installation notes The four mounting holes in the base plate of the PowerBox Royal SRS are fitted with rubber grom- mets 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.

  • Page 8: C) Setting The Receiving System To Be Used

    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.

    7.4 V for regulator pair A, and 5.9 V for regulator pair B. This feature makes it possible to connect a mixture of HV servos and normal servos to the PowerBox Royal SRS. The markings A (red) and B (black) on the case cover indicate which outputs are assigned to range A, and which to range B.

  • Page 10: F) Channel Assignment, Output Side

    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 out- puts. The menu point where this is carried out is entitled OUTPUT MAPPING: This menu displays a graphic image of the outputs.
  • Page 11 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.

  • Page 12: G) Using The Igyro Assistant

    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: Direct 5 / VALVE sequencer free R.H.
  • Page 13 Before you carry out the fine-tuning flight we strongly recommend that you run through the TEST- FLY 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.
  • Page 14 Note: many model jets and warbirds utilise a large number of functions, and you can quite ea- sily “run out of channels”. However, the Royal SRS provides the complete remedy: use just one channel at the transmitter for each of the functions ailerons, elevator and rudder / nosewheel steering, then use the Servo Match function to set up the second control surface, and adjust the direction and end-points accurately.

  • Page 17 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.

  • Page 20: H) Using The Door Sequencer Assistant

    Access the PowerBox’s Door Sequencer menu, and select the SETUP ASSISTANT point. You will now see the following screen display: At this point the Royal SRS learns which switch is to be used: the unit automatically detects the appropriate channel when you operate the transmitter switch you have assigned for the retractable undercarriage.
  • Page 21 The purpose of this menu is to set up the way the door sequencer operates. The following basic sequences are available: Mode 1: Extend undercarriage: Wheel doors open Undercarriage extends Retract undercarriage: Undercarriage retracts Wheel doors close Mode 2: Extend undercarriage: Nosewheel doors open Nosewheel extends Main undercarriage extends...
  • Page 22 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.
  • Page 23 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.
  • Page 24 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.

  • Page 25: Channel Assignment, Input Side

    The integral Fail-Safe and Hold function makes it possible to program fail-safe or hold mode in the Royal SRS without recourse to the transmitter or receiver. Each output can be set up individually. Example: it would be possible to assign fail-safe to throttle if complete signal loss occurs, while all other outputs maintain the last known valid position.

  • Page 26: Igyro - Detailed Description

    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. Use the transmitter to move all the model’s control surfaces, the undercarriage and the throttle to the positions which you want them to take up if a fail-safe situation should occur, then press the SET button: this action stores your selected positions.

  • Page 27: B) Speed-Dependent Gain Control

    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 se- cond.

  • Page 28: D) Defining The Installed Orientation Of The Royal Srs

    TINGS menu. e) Defining the wing type The Royal SRS features an integral Delta and V-tail mixer, which makes it possible to fly deltas and V-tailed models with heading-lock gyro stabilisation! This menu can be activated in the GENERAL SETTINGS menu: simply select MIXER: DELTA-WING or V-TAIL.
  • Page 29 VIII) Disable the rotary knobs or sliders The Royal SRS is installed in the model, and the control surface channels and Flight Mode switch have been assigned. Gyro gain should be set to 0% on all axes and in all flight modes.
  • Page 30 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”...
  • Page 31 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.
  • Page 32 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 separa- te aileron channels, repeat this procedure for AILERON-A and AILERON-B.

  • Page 33: G) Zero Gyro

    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 pres- sing the SET button twice.

  • Page 34: H) Boost

    Important information on handling the iGyro in day-to-day flying - Switching the system on When you switch the Royal SRS on, it adopts the current stick position as Centre. For this reason it is important to avoid touching the sticks when you switch the system on.

  • Page 35: Manual Door Sequencer Installation

    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.
  • Page 36 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.

  • Page 37: Channel Lock When Undercarriage Is Retracted

    9. CHANNEL LOCK WHEN UNDERCARRIAGE IS RETRACTED The PowerBox Royal SRS’s door sequencer also features one last unique function: it is now pos- sible to switch a channel off when the undercarriage is retracted. The purpose of this feature is to prevent the retracted nosewheel moving inside the fuselage when the pilot gives a rudder com- mand, as this may cause the mechanical system to jam.
