    Product description

    The PowerBox Royal SR2 once again sets new technical standards, offering a convincing array of features which until now have been the exclusive preserve of professional aviation. P² servo bus, 26 channels, 12-axis gyro, two pairs of regulators and a full-color screen - these are just a few of the technical refinements which the PowerBox Royal SR2 offers the ambitious pilot.

    The PowerBox Royal SR2 is housed in a high-quality, extremely compact case with integral aluminum heat-sink. The large cooling area dissipates the heat generated by the four regulators, which are wired in pairs to provide energy for all 26 servos. Both regulator pairs can be set to any of four different voltages. This makes it possible to combine standard 6V servos with high-performance HV types, without additional regulator modules.

    For the first time all the data relating to all the model’s servos can be monitored, and their parameters adjusted¹ from the transmitter. This development has been made possible by the introduction of our P²-BUS protocol, whose aim was to maintain complete control of all the components in the model. The PowerBox Royal SR2 has four fully independent P²-BUS interfaces, which can be set to two different voltage levels.
    These interfaces can be used to connect servos with an integral P²-BUS, or conventional servos with the new P²-ServoBridge. The P²-ServoBridge is an adapter which converts the P²-BUS into a PWM signal for normal servos; it also has an integral infinitely variable electronic fuse.
    This has allowed us to implement a bus system in the model which is significantly superior to standard PWM wiring in respect of security and performance.

    All data relating to the receivers and power supply system are displayed on the full-color screen, and all settings are available in a carefully structured, bi-lingual menu which is easily understood.
    The TFT screen is also housed in a high-quality aluminum case, and is clearly legible even in full sunshine.

    Connecting the optional iGyro SAT converts the PowerBox Royal SR2 into a 12-axis gyro which has few equals in terms of functionality. The gyro can be set up to suit even the most complicated of models in just a few minutes. After this, the correct gyro gain is set from the transmitter in a test-flight using a rotary control. A whole series of supplementary Expert settings is available to allow the pilot to fine-tune the gyro effect to suit his unique individual preferences.
    Naturally a GPS III sensor can also be connected to the PowerBox Royal SR2. This unit provides automatic gyro gain adjustment in relation to airspeed.

    The PowerBox Royal SR2’s 26 outputs are provided with an ample power supply, and they can also be assigned individually to various functions. All outputs can be allocated direct and gyro channels as well as door sequencer functions.

    The PowerBox Royal SR2 has an automatic servo-matching function which is a new development. This system makes it possible to match a maximum of three servos to each other automatically in just a few seconds using five points. All you have to do is select the servos which are inter-connected mechanically, and start the automatic procedure.
    Of course, each output can also be adjusted manually using the servo-matching function and the graphic-based menu.

    The final aspect of the system is its pair of integrated door sequencers. In addition to a retractable undercarriage, it is possible - for example - to implement a latched opening canopy control system without additional devices. The first door sequencer can be set up in just a few minutes with the help of a Setup Assistant, and three modes are available.
    Additional special settings are equally easy to set up thanks to the on-screen diagrams in which the entire timed sequence can be seen at a glance.

    The PowerBox Royal SR2 can be set up and controlled virtually completely² from PowerBox and Jeti transmitters! Telemetry for every aspect of battery and receiver data is available for all supported systems. If a GPS III is connected to the unit, GPS data are also available - in so far as your radio control system supports this.

     

     

     ¹ The P² servo bus system works with all radio control systems - as was the case with the previous PowerBox Royal SRS. It is even possible to connect the P²-ServoBridge directly to the data port of the PowerBox Royal SR2 for adjustment. This eliminates the need for an additional USB or Bluetooth adapter in order to adjust the channel assignment or the cut-off current.
    P²-BUS servos and the P²-ServoBridge can be adjusted from the transmitter, but only in conjunction with PowerBox transmitters. The telemetry data from the individual servos can also only be transferred if you are using the high-performance telemetry system offered by the Core and Atom radio systems.

    ² With the exception of the sequencer and the Setup Assistant

Amazing WDT Tool!
Color: Black
This WDT tool instantly improved the evenness of my puck prep, and the difference in my shots was obvious. The ultra‑fine needles fluff the grounds perfectly without creating channels. It has a nice weight to it and feels like a real upgrade compared to cheaper plastic options.

Has upped our coffee game :)
Color: Sliver, Color: Sliver
EDIT: Well, 2 months later, this is still performing okay, however some of the needles have gotten slightly bent, causing it to seem loose and wobbly as they rotate within their opening. . Not a great aspect of this design. If you loosen the head straighten any bent needles, it does help a little bit. So far so good. It’s made a little difference in our coffee. We buy espresso beans and so we really pay attention to the way the espresso acts from cup to cup. We notice that after using this tool our coffee is a little sweeter, probably because the way the grounds are so evenly distributed and the little channels that the wires create. Easy to use, store, and keep clean. And it’s cute on the counter!

Big Improvement in Espresso Consistency
Color: Black
This WDT tool made a noticeable difference in the quality of my espresso shots. The needles are thin enough to break up clumps and create a very even coffee bed, and the distribution feels smooth and controlled. Build quality is solid, the handle feels comfortable, and it’s easy to clean. I’ve gotten more consistent extractions and better flavor since using it. For anyone looking to upgrade their espresso workflow, this is a simple but very effective tool. Definitely worth it.

Impressed
Color: Black
I rarely give 5 star reviews. This product deserves it. A lot of thought has gone into the design. First, the material of it is quite good, metal. It has a contoured and knurled top for ease of use and good grip without being "grippy". The recepticle has little brushes inside which I think is unique to this product. Will those brushes created a problem in the future? I don't know. But there must be a way to clean out the coffee dust at some point. An air blower? Until now I had been using a home-made WDT with acupuncuture needles drilled into a cork. When I used the Nessus WTD I could immediately feel a difference as I stirred the grounds. While I have only made two double-shots so far, there was noticeably less channeling that I had before (I use a bottomless portafilter exclusively). Actually I had no channeling, but initially two streams that mergedi into one in about 3 seconds, so pretty good compared to what I had before. Nothing much more to say except the price was quite good compared to other WDT's. Even though I haven't used this product more than a few times, I can, at least at first blush, recommend it.

Works well out of the box, and better with a tweak.
Color: Black, Color: Black
This is a solid, well-made WDT tool that does exactly what it’s supposed to do — and gives you room to fine-tune it to your preference. The build quality feels good in the hand, and it works well right out of the box. A big plus is that it comes with extra needles, which makes it easy to change out bend needles or customize. I found that removing some of the needles actually improved usability for me. With all nine installed, it tended to push grounds around too aggressively. I’m currently running just 3 needles, and that setup works much better for gently breaking up clumps and distributing grounds without pushing or spilling coffee over the basket. Once dialed in, it’s been very effective and consistent. Overall, this is a great tool from TIVERAIN. If you like dialing in your workflow and want control over how aggressive your WDT is, this one is a great option.
