The Powerbox Royal SRS is the top of the line of Powerbox 4 regulators systems.
Current requirements obliged us to adopt many new ideas during the development period: these include the triple-axis iGyro as well as our new PowerBus technology, which is destined to introduce fundamental changes in the electronic layout of large-scale models as a whole.
In other respects we have retained proven concepts in further developed form. For example, the new Royal SRS is fully programmable using a menu system, controlled with the SensorSwitch and a blue backlit LCD screen; as usual, all battery-specific and flight-relevant data can be displayed on-screen after each flight.
The door sequencer function and the internal iGyro both feature integral set-up assistants which make it possible to complete the essential set-up procedures in very short order.
Over the last two years developments in serial receiver bus systems have brought them to the forefront of current technology, and the new Royal SRS features these inputs.
The Royal SRS features no fewer than four high-performance voltage regulators, allowing the use of both HV servos and conventional 6 V types. With dual security in mind, each pair of regulators can be set to an output voltage of 5.9 V or 7.4 V.
The Servo-Match and Fail-Safe functions have also been expanded: the software now provides adjustment facilities for all 24 outputs individually, covering servo centre, travels, fail-safe and hold-mode. Servo reverse is available with a single button-press.
Six different radio control systems - Spektrum, Futaba, JR, Multiplex, Hott and Jeti - can be bound to the Royal SRS, most of them providing telemetry output of battery-, receiver- and GPS data.
The Royal SRS can be updated using the USB adapter, and is therefore equipped to cope with new systems in the pipeline and possible future expansions.
