    Product description

     

    It is now ten years ago to the month that the first Competition SRS was introduced. At that time it represented a milestone in the redundant deployment of receivers using our new type of bus technology. The unrestricted output assignment, servo matching and linking to early telemetry systems were unique features, and remained so for a long time.

    Technology has continued to develop, and modellers' requirements have become more exacting. Here at PowerBox Systems we are proud to present our latest development: the PowerBox Competition SR2. Incorporating a new external look and the very latest technology, this single unit integrates more than twenty years of experience in the design and construction of airborne electronics.

    The external changes are immediately evident: the most obvious and eye-catching feature is the new full-colour TFT screen, which is clearly legible even in full sunshine. The size of the screen has allowed us to include a self-explanatory menu structure which is so simple to use that its operation has raised not a single query from our test-pilots. Another obvious change is the large heat-sink, machined from solid metal, which significantly enhances the performance of the power supply. At the same time we were able to reduce the overall size of the Competition SR2 substantially. The associated Sensor-Switch and TFT screen are also housed in a machined aluminium case, matching the quality appearance of the SR2 itself.

    However, the most significant innovations only become evident once the unit is switched on. The main display contains all the essential data - including battery voltage, current, consumed capacity and all receiver-relevant information - which can be viewed at a glance. The screen also displays status messages concerning the iGyroSAT or GPS III, if connected to the system.

    The menu system is clearly and logically laid out, and includes many new functions as well as the familiar menu points - and all in two languages: German and English! Important new features implemented in the new Competition SR2 include the most efficient and sophisticated iGyro technology ever developed by PowerBox-Systems.

    Used in conjunction with the optional iGyroSAT sensor, the system offers twelve gyro axes which cater for every existing model variant. The highly refined Setup Assistant enables the pilot to set up complex models, such as types with dual thrust vectors, ailerons and tailerons, in just a few minutes. Once the Assistant has been completed, the transmitter channels are assigned, the directions of gyro effect are set, and the servos connected to the outputs.

    Each gyro axis can also be finely adjusted individually from the transmitter using separate channels. If an initial test-flight shows up a need to fine-tune the iGyro to meet individual requirements, a whole series of Expert settings cover every possible need.

    The servo matching feature is now displayed in graphic form on the screen, and the PowerBox Competition SR2 also allows the servo response to be adjusted using five curve points. A new development is automatic servo matching. It is a very simple matter to assign and select one or two servos in addition to the primary one, and these two or three servos can be matched accurately to each other in just a few seconds with a single button-press!

    The Competition SR2 incorporates two independent door sequencers. The standard function is designed for a retractable undercarriage, while the second can be used to implement systems such as a latching canopy control system without any additional devices. The Setup Assistant is capable of setting up the first door sequencer in just a few minutes, and three modes of operation are available. The graphic on-screen display makes additional non-standard settings very easy to set up; the entire sequential process can be observed at a glance.

    If you use a PowerBox or Jeti RC system, virtually all* the functions of the Competition SR2 can be controlled and adjusted from the transmitter. The SR2 caters for every aspect of telemetry for battery and receiver data with all supported systems. If a GPS III is connected, then GPS data are also available - limited only by the facilities of the RC system in use.

Good set of clubs for beginners to find out if golf is their game! You'll need a putter, though.
Hand Orientation: Right, Color: Blue/Black
This nice inexpensive set is great for a beginner at golf, which is me--never played before. I don't evem know if I'm going to like playing, but at least I have a set of clubs so that I can give it a try...it's the exercise from walking the course that appeals to me. My son says he can teach me, even using mens clubs. I figure if I like the game, I can get a nicer set of ladies clubs and pass this set to my grandson. If I don't like the game, I can still pass the set along to my grandson! My son thought these clubs were decent weight and quality and well worth the price...the only thing missing was a putter, but we found a cheaper one to add to the set.

Solid Paddle Solid Price
Color: Blue*1
I am a beginner with Pickleball. However, I started using a $5 from 5 below and this paddle was a huge upgrade. The grip felt really good, solid in my hand with a little cushion. It was a solid and much sturdier than the previous paddle. This was a small investment in a great hobby that anyone can enjoy. I also think they really take care of you by giving you a case so it does not get scratched. I highly recommend. There truly was no downside I could think of to getting this. If you are a beginner like me, its a quality paddle at a quality price. no brainer

Just what you need!
Color: Green Black*4, Color: Green Black*4
This set is just what we needed for the 4 of us to play a nice game of pickleball. The quality is good, the carrying case keeps it all organized, and we keep it conveniently in the trunk of our car. It’s held up well even though it’s taken some beatings. Unless you’re a professional, it’s just what you need! Nice grip, handle is the right size, the weight is light; making it easy to use, and it’s created no issues with gameplay. Great deal for good quality equipment!

Pickleball Pandemonium: A Hilarious Mother’s Day Misadventure with a Top-Notch Paddle Set
Color: Blue*4
Let me spin you a tale of how I, the hopeful boyfriend of my girlfriend with two adorable-but-feral nieces, ages 3 and 5, tried to be the cool guy on Mother’s Day with this USAPA-approved fiberglass pickleball set. Spoiler: it was less “heartwarming family moment” and more “backyard dodgeball with extra chaos.” This set, though? Absolute gold for adults—just don’t hand it to toddlers unless you’re ready to star in a slapstick comedy. So, picture me, all bright-eyed, pulling out this slick pickleball set at my girlfriend’s sister’s place. The kit comes with paddles, balls, and a good-quality case that’s sturdy enough to survive a trip through an airport baggage claim. I’m thinking I’ll set up a mini court, show the nieces what pickleball’s all about, and maybe earn some “best boyfriend” points. In my head, it’s all slow-mo high-fives and cute kid giggles. In reality? I handed those paddles to the girls, and it was like arming gremlins with medieval weaponry. These paddles are *chef’s kiss* for grown-ups. The fiberglass surface gives a satisfying pop when you hit the ball, and the handles? Oh, they feel nice—comfy grips with just the right amount of cushion, like shaking hands with a friendly lumberjack. Plus, they’ve got some good weight to them—not so heavy you’re winded, but enough heft to feel like you’re swinging something legit. The balls are what you’d expect: standard, bouncy, perforated orbs that do their job without any surprises. But for kids? Disaster. The 5-year-old, who I’m calling Paddle-Wielding Warlord, grabs her paddle and swings it like she’s auditioning for *Gladiator*. First shot, she nearly takes out her 3-year-old sister, Tiny Catapult, who’s just vibing with her own paddle. I’m ducking near-headshots, yelling, “Gentle! Gentle!” while my girlfriend’s cackling so hard she’s got tears. Then there’s the ball situation. I lob one softly, thinking they’ll tap it back. Nope. Warlord yeets it across the yard like she’s gunning for the moon. It’s gone—probably chilling in the neighbor’s birdbath. Tiny Catapult, not one to be outdone, hurls her entire paddle, which spins through the air like a rogue frisbee. Flowerpots are in peril, my girlfriend’s sister is shouting about her azaleas, and I’m just trying to keep the nieces from turning this into a full-on demolition derby. The case, bless its durable heart, sat there safely holding the spare balls, mocking my poor life choices. Later, when the kids were safely bribed with ice cream and the adults got a turn, the set shone. My girlfriend and I rallied in the driveway, and those paddles felt like an extension of my arm—smooth, balanced, and ready for action. The USAPA approval means you could take these to a real court and not look like a chump. But for the toddler crowd? Yikes. Get those foam kiddie paddles that can’t double as blunt objects. This set’s a 10/10 for adult fun, with a bomb-proof case and gear that feels pro-level. Just don’t expect the under-6 crew to do anything but turn your yard into a *Mad Max* reenactment.
