New BEC for Stable HD Image Transmission
Digital image transmission requires higher current, and 1S whoops often fly at voltages as low as 3.3V, placing significant demands on the BEC. To meet these challenges, an advanced BEC has been developed, capable of delivering over 3A of current at ultra-low voltages down to 2.85V. This ensures stable digital image transmission even in critical situations. While flying to such low voltages isn't recommended, this innovation provides pilots with a greater chance of safely recovering from unexpected situations.
Enhanced Continuous 12A ESC
HD image transmission adds weight to 1S whoops, demanding stronger power and higher ESC overcurrent capacity. Our engineers exceeded expectations, delivering a robust ESC with 12A continuous output and 18A peak capacity on the iconic "cross" flight controller. This ensures optimal thrust-to-weight ratio, reliable performance, and worry-free high-definition flights.
Individual Power Supply for IMU
Unlike traditional shared power supply designs, the Matrix 1S 3IN1 HD FC features an independent 3.3V LDO power supply exclusively for the IMU. This innovation eliminates interference, creating a cleaner and more stable environment that enhances flight precision, improves sensitivity, and reduces the risk of performance issues—ensuring unmatched stability during every flight.
Effortless Setup and Maintenance
The Matrix 1S 3IN1 HD FC is designed to maximize your flight time by minimizing setup hassle. Equipped with convenient motor plugs and a SH1.0-6Pin HD digital port, it allows for a completely solder-free installation and maintenance process. Now, you can focus more on enjoying high-definition flight experiences instead of dealing with complex tools.
Serial ELRS 2.4G RX
Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS V3.0 with no need to flash Betaflight flight controller firmware. Enter binding status by power on/off three times.
- Plugin and unplug the flight controller three times;
- Make sure the RX LED is doing a quick double blink, which indicates the receiver is in bind mode;
- Make sure the RF TX module or radio transmitter enters binding status, which sends out a binding pulse;
- If the receiver has a solid light, it's bound.
The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.
- Plug in your FC to your computer, connect to ExpressLRS Configurator instead of Betaflight Configurator;
- Choose target "BETAFPV 2.4GHz AIO RX";
- Flash using the BetaflightPassthrough option in ExpressLRS Configurator.
How to flash firmware via Wi-Fi here.

A cat, a murdered author, and a librarian cum sleuth - what more do you need?
Format: Kindle
Murder Past Due has it all. A small town where everyone knows everyone, return of the prodigal son, murder, and a just-nosy-enough archivist with connections to them all. My favorite character is Diesel, the cat, though his primary role is as a comforting presence. I would have been happy with more of a supporting role for him—there were a few moments where I thought he would get one, but it didn’t quite take off.
The mystery engaged me and kept me reading. I had it nearly figure out in the last fifty pages, but there were satisfying twists leaving me pleasantly surprised right up to the end.
I was distracted by excess verbiage (Southern style?), and something ever so flat about the main character. He said he was surprised or upset or missed certain people, but I just didn’t feel it.
Still, I think I will read book two, and that merits a solid four stars.

The cat didn't do it!
Format: Mass Market Paperback
I bought the book, because it looked so cute. Plus, I love cats! It was a cozy mystery with the cat as a constant companion of the protagonist. It made for a delightful story. I don't usually read low key mysteries, but I thoroughly enjoyed the humor, the cat, and the murder mystery. I plan on buying the next one. Ms. James has a writing style that you will enjoy her stories. You will not get bored.

When A Mystery Writer's Death Becomes The Mystery
Format: Kindle
Charlie Harris is a part-time archival librarian for Athena College in Athena, Mississippi. In his late forties, the father of two grown children, and a widower for three years, Charlie is the proud human owned by a Maine coon cat named Diesel. Still grieving the loss of his wife, Charlie is not yet interested in dating and keeps himself politely at an emotional distance from everyone except Diesel.
Coming into Charlie’s life about two years ago as a bedraggled kitten wandering the library parking lot, Diesel seems to have two particular affinities. He seems to understand the human language well beyond the sound of his own name or the phrase “Here, kitty kitty.” And he seems to sense and differentiate between human emotions, particularly sadness and anger, even when not verbally expressed. Weighing nearly 35 pounds and not yet fully grown, Diesel proudly sports a harness and leash and goes just about everywhere with Charlie. He openly seeks attention from everyone he meets but he gives back just as much or more after he “determines” the type of attention the human needs at the time.
For all that we know about Diesel, we know very little about Charlie other than what I have already mentioned. The author never physically describes Charlie, not height or hair color, not weight or eye color, not anything. Since every other character is described as he or she enters the storyline, the absence of same for Charlie seems to be deliberate on the part of the author. Thus, each reader can visualize our main protagonist in whatever form fits or feels right at the time.
While Charlie has eschewed emotional attachments since the nearly concurrent deaths of his wife and his favorite aunt, he rents out rooms to college students. As our story opens, one of the boarders, 18-year-old Justin Wardlaw, experiences three traumatic events in one day. First, he meets his previously unknown biological father for the first time. Secondly, the man he thought was his father strikes him in the face when he refuses to quit college and move back home. And, finally, he discovers the body of his biological father murdered in his hotel room.
Godfrey Priest, the murdered man, is a best-selling author of violent thrillers that have a severely misogynistic overtone. A contemporary of Charlie, he grew up in Athena with a well-deserved reputation as a physical and emotional bully. Needless to say, there are many people in town with long memories and hardened hearts as far as Godfrey Priest is concerned, making no dearth of possible suspects.
Miranda James does not portray Charlie as a suspect who must work to clear his own name. Nor does she portray him as one of those meddlesome types who feels he can do better than any police detective in existence. What she does is portray Justin as a good kid who has just been handed a very raw deal and is in dire need of help and adult support. Since Charlie is a well-respected research and archival librarian trained to find answers to oblique questions, he decides to lend those skills to Justin’s cause.
And then there is the police detective, Kanesha Berry. Detective Berry is smart and intuitive but she has the people skills of a rock and the professional personality of the rattlesnake hidden under that rock. She is also the daughter of Charlie’s longtime housekeeper, Azalea. When Azalea asks Charlie to use his skills to help her daughter succeed in spite of herself, Charlie finds himself in the position of unofficial private investigator.
James has written a solid first entry for her Cat in the Stacks series. The search for the murderer twists and turns as past deeds surface and motives multiply. Since the book is written from Charlie’s first-person POV, the reader knows no more than Charlie does at any time. And since the author writes the detective as a recalcitrant soul, fighting for control and against civilian assistance, the reader gets no help whatsoever from that quarter toward interpreting the information that Charlie gleans.
Charlie makes mistakes, both intuitive and legal. Unlike what happens in many cozies, our protagonist immediately accepts responsibility, takes his lumps and makes a concerted effort to correct his behavior. And, unlike the progression in many cozies, he doesn’t figure out the murderer’s identity before the detective does.
This novel has no obvious hook leading to another book. Nor does it end in a cliffhanger. But the murder of Godfrey Priest, and his investigation into it on Justin and Azalea’s behalf, changes Charlie. And on that point lies the premise of another book.

Surprisingly Deep and Heartfelt
Format: Paperback
At first, when i started this book, i didn’t quite know how to feel about it.
It’s pretty slow in the beginning, about 30 percent is just them being “hateful” towards each other while actively not trying to acknowledge the obvious physical and emotional chemistry between them.
The more and more i flipped the pages, the more i fell in love!!
Ryan is the epitome of the best book boyfriend you could imagine.
He’s patient, kind and thoughtful.
Although, at times, i thought he and Josie both were too judgmental of each other and what the other enjoyed to spend their free time reading.
So what, he reads romance?
And so what, she doesn’t read romance?
But as we get deeper into their story, we realize they each had their own reasons for having their opinions.
This story was surprisingly very insightful, loving and deep.
Not too deep to where you’re contemplating your life choices, but deep in the sense that you will be thinking about these characters and their abilities to over come trauma and presumptions about themselves and their careers.
With that being said, i think that Ryans employees, specifically indira, were way too judgmental.
They saw for themselves how Ryan also treated Josie, and he typically was more rude to her than she was to him.
Especially being women, reading romance and working at a romance store, they should know how it feels for people to be prejudice about a Genre they enjoy, and should be mindful and have told Ryan to be kinder.
That being said…at times Josie was, i will say, a prude.
Especially in the scene where ryan had her read “beach read” by Emily Henry Aloud and she texted RJ and said that women and men dont have intimate moments like that IRL. She was almost disgusted at the idea of having good, respectful and yet “mind blowing” s3x. I thought it was childish of her, honestly.
You’re 30. Grow up.
Georgia, her sister, was also too almoy judgmental of Josie and her trauma growing up with their mother. Especially for someone who was becoming a psychiatrist. She didn’t seem to take into account the things she dint see growing up, because Josie spent her time shielding her and protecting her from all the chaos.
Other than that, that was the only few times this book pissed me off.
All in all i’d give it a 4.5 out of ten!

If you are looking for a book with excellent banter, easy-to-love characters, and a romance that will completely charm you, put this one on your TBR immediately! 📚✨
Let’s talk about the character dynamics because they absolutely stole the show for me:
🛡️ The FMC: Josie Klein wears an emotional suit of armor and is a little rough around the edges when it comes to letting people in. If you love Ali Hazelwood’s FMCs, you will fully understand and adore Josie. Watching her walls come down was everything.
🐾 The MMC: Absolute GOLDEN RETRIEVER energy. He is a big softie with a heart of gold, but—and this is the crucial part—he isn’t afraid to put his foot down when it matters. The perfect balance.
The banter between these two was top-tier, and the entire setting had me hooked from start to finish. It’s an absolute 10/10 for me!
