HDZero Halo Stack – Flight Controller + 4in1 70A ESC
The HDZero Halo Stack combines the Halo Flight Controller and Halo 4in1 70A ESC into a race-ready powertrain, engineered by HDZero—leaders in high-performance digital FPV systems. Designed for power, reliability, and ease of assembly, this stack is the ultimate solution for competitive racing and freestyle pilots.

With its clean layout, minimal wiring, and integrated components, the HDZero Halo Stack is the easiest way to build a professional-grade racing drone—without sacrificing performance, reliability, or serviceability.

At its core is the Halo 4in1 70A ESC, built for extreme durability and responsive throttle. A split-board design separates control and power stages, improving thermal performance and crash resilience. With 24 MOSFETs across an 8-layer PCB using 3oz copper per layer and a rear-mounted copper bar, the Halo ESC delivers exceptional burst throttle response with minimal voltage drop. Rated for 70A continuous per motor and 100A bursts, the ESC supplies clean, stable power while protecting sensitive electronics from voltage spikes. A conformal coating adds moisture, dust, and corrosion resistance. Choose between BLHeli32 (fw 32.10) or AM32 firmware based on your preference.

The Halo Flight Controller simplifies your build while delivering professional-grade control. Powered by an H7 processor, it integrates a Gemini true diversity ELRS receiver, using dual independent receivers for rock-solid control link stability. A TXCO (temperature-compensated crystal oscillator) maintains consistent ELRS performance even in extreme temperatures—essential for race conditions.

The integrated ELRS RX not only simplifies quad assembly but also provides a cost-effective solution. With the Gemini ELRS RX typically priced at $25, this combination represents significant savings compared to purchasing separate ELRS receivers and flight controllers.

Built for digital video systems, the Halo eliminates the analog OSD chip to reduce costs and save space. It is specifically designed to allow the HDZero Race v3 VTX to stack on top of it in a low-profile manner, resulting in a durable and compact stack height. This optimization ensures a secure, space-efficient build while maintaining excellent performance.

The Halo FC requires no soldering for VTX, receiver, or ESC connections. Everything plugs directly into dedicated sockets using included cables, making assembly and field repairs fast and frustration-free. This low-profile, modular design results in a tidy, durable racing stack.

The switchable 9V BEC powers your HDZero VTX, with remote control over power via Betaflight to simplify pit stops and extend VTX lifespan. A separate 5V/4A BEC is capable of powering an entire competition-grade LED setup without the need for external regulators.

The Halo Flight Controller is available in two versions, MPU6000 and ICM42688, to meet different pilot preferences.

High on Tropes and Satisfaction
Format: Kindle
This is a great Romantasy book full of action, adventure, and everything you look for in this genre. I won’t lie: it does kinda feel like the author found every common trope from every successful book of this kind and threw them all into this novel. But if it ain’t broke, don’t fix it. Especially in romance, there’s a large audience who has specific expectations, and they want them every time. Nothing wrong with that and many times I’m one of them. I have no idea what defines a spoiler honestly, so spoiler alert!!!!!!! Tropes include: Only one bed at the inn/bar Dissatisfaction with life before hunk appears Lost royalty The chosen one Montage of dress up time followed by shocked hunk Forbidden romance between two from rival peoples Power that cannot be controlled, simply guided/asked Gathering intel at the inn/bar FMC who knows how to fight/use weapons well There’s probably more but no need to list them all. Good story and I would recommend!

AMAZING debut novel!!!
Format: Kindle
Plot ⭐️⭐️⭐️⭐️ Spice 🌶️🌶️.5 Romance 💘💘💘 Vibes ⭐️⭐️⭐️⭐️⭐️ Dual 1st person POV - Ara (26) & Rogue (39 - but looks mid-20s: they can live hundreds of years so this isn't that large of a gap as it could've been which I heavily appreciate lol) Tropes: enemies to lovers, fae/human wars (deep hatred for each other), shifters (dragons- MMC can only partial shift with wings), one horse, one bed, touch her and d!e, found family, abduction turned to freedom The Last Storm is the debut novel from JD Linton and let me tell you, you guys NEED to read this. The plot was engaging and the editing was was amazing (especially for a debut novel). Our FMC, Ara, is stuck in her gilded cage longing for a life outside of her small town. She uses her books to escape and live vicariously through the pages (honestly, relatable). After her father announces her betrothal to her childhood friend (to whom she has no romantic feelings for), Ara tumbles unknowingly into a desperate plot trying to stop the humans from slaughtering the Fae. As one can expect from an enemies to lovers / kidnapper/captive romance, Ara fights her attraction and lust towards our MMC, Rogue (the King of the Fae), for as long as she can. Upon seeing Ara for the first time, Rogue is instantly aware that she is his fated mate (not a spoiler). Since she is the General's only daughter, he plans to abduct her and use her as leverage to stop the brutality. During Ara's time in Rogue's captivity, their banter and chemistry continue to rise until they finally boil over and come together (quite literally, and many times I may add 😉). Here's what I LOVED: - Rogue continuously seeks advice from his elders and deeply respects their opinions and life experience and tries to implement their recommendations - Rogue makes many mistakes in the beginning but we see him actively work on not repeating them as the book progresses. The level of self-awareness and his ability to change his behavior was impressive - The magic system is intricate and we have only scraped the surface. As the series continues and Ara progresses in her powers, I'm sure we'll get to see more of this. I absolutely LOVE the messaging system that is used in this book. - Ara's struggles are so human and so raw. She is experiencing so much guilt and pain and hurt and getting to see her work through each of these emotions is inspiring. Especially as her and Rogue get closer and she learns she can lean on him as well, that she is not alone. - While this is the start of a series, there is NO cliffhanger! There's a bit of a teaser of something major that is going to happen at the start of the next book, but it's not a cliffhanger in the sense that we aren't sure if someone is going to live or d!e or if they'll be separated. For that, I am very thankful! This book was so much fun that I will definitely be returning to book 2, even if it takes several months (or longer since this is an debut author) to publish! - Lastly, the cover is GORGEOUS! And I love the title! I'll copy a few of my favorite quotes below so you can have a little taste of the author's writing and the world she's cultivated. 😊 Top Highlights from The Last Storm On days like this, when my heart was heavy and my mind clouded, I resorted to books— to escape, to forget, to find freedom where I had none. If I were to marry him, my face would always be turned to the window, searching for more, and if not that, I would be a shell of the person I am now. I stepped back to admire her, thr0bbing at the sight. She was the most beautiful woman I had ever seen. To ever exist. Nothing, no one, had ever deserved to be worshiped more. All men should be made to kneel before her. But she would have to settle for me. The taste of her met my t0ngue as my scent merged with hers, forever branding her. Mine. I l!cked the wound. Hers. Completely and utterly hers. I didn’t claim her in ownership. I claimed her as my one. Devoted myself to one. With that mark, my body and soul were bound to her. I would never be with anyone else, emotionally or physically. It would be her or no one, until my last breath. “Scream my name. Let everyone know who I belong to.” I had never really cared about the weather before, but now, clear skies meant everything to me, and I was grateful to see another calm morning. “There will never be another woman for me.” He paused. “Ever.” I stilled at his words. “What… Why?” “This”— his thumb slid down across the mark—“ is a symbol of… surrender. I know you believe that it was my claim upon you, but it wasn’t. It never was. I bound my body and soul to you, little storm.” “I also know that it is more than this tiny, insignificant mark on your skin that binds me to you. It’s you. All of you. Your strength and resilience. Your determination to endure no matter what fate throws at you. Your love for love and stories and hope. You are entirely the opposite of everything that I am and I would gladly wear your shackles if it meant I could have you.” My mate. Mine. And then everything shifted and I understood. I understood everything. The surrender. The deep, soul-craving longing. Bound. I was bound to him. Body and soul. Entirely his. “I would’ve waited forever,” he whispered back, understanding. Seriously, everyone.. add this to your TBR!!

A Decent Fae Romance
Format: Kindle
** 3.5 Stars rounded up to 4 ** First off I want to say that I found the author, J. D. Linton, on TikTok right before the release of the sequel. I bought the first 2 books to support her release, so congrats to her for the release of the sequel! Overall, I liked the story & plot, I liked the characters, and I liked the spice. The downfalls: not enough development between the characters for the romance, and it leaned a little heavy into the tropes. A lot of stuff is told to you, which could have been used as devices to drive the plot and emotions of the characters. 🛑🛑 Mild Spoilers ahead, I tried to hide the obvious ones 🛑🛑 This is very obviously a fated mates, which is a trope I usually really enjoy. But I wish the relationship between Ara & Rogue had much more development before it's realized that they're mates, instead of Rogue knowing almost immediately and using it for nefarious purposes (at least in the beginning before they get to know each other). By revealing this within the first quarter of the book, I feel like it leaves less room for them to fall for each other organically (albeit with help from the mating bond) and they love each other because of the mating bond. I was disappointed as soon as Rogue know (literally only 5% in) and I literally made a note: "As much as II love a good mating trope, I wish we had to work for it a little more. Where's the fun in just telling us?" I believe that by holding out and feeding the reader snippets of a potential bond, it would've been more rewarding as a reader. I also wish there was more world building - we are told of a war between human & fae but don't get to really experience any of it. Ara is sheltered in her human home, then sheltered in Rogue's castle. There's bits and pieces about what the war has done on either side - but we're more told of the aftermath and don't really experience any of it. Ara's father is supposed to be the king's #1 general - yet he is at home with his family & with Ara for the first couple chapters. Her, her family, nor her village seem to be affected by the 10 year war going on on their borders. I wish there was a little more setup to make this conflict - an actual war - feel more than a skirmish between fighting territories. Linton could also be a little repetitive - with the biggest culprit being when Ara is upset she "brings [her] knees to [her] chest]" and either sits like that or cries. Every time she is upset this phrase is mentioned. I would get it if this was her crutch, or how she copes with grief and stress, but that should be explained why she does it so often or it becomes repetitive. I started to get annoyed with how often she would sit like this solely because it happens every couple chapters. However, I did really like the spice. I love an enemies to lovers trope, especially when it results in spicy scenes. The spicy scenes weren't anything new, but they were fun. Wish there were more but that could also just be me - there is no such thing as too much spice 😂 Would I read again? Probably not, I'm super picky with rereads. Although I did genuinely enjoy my first read through! Will I continue the series? Probably, at least for the sequel. As for #3, kind of depends on where I am with my TBR once that is released All in all an enjoyable, fast paced read

I love indie authors
Format: Kindle
Let me preface this by saying—writing a book is HARD! Coming up with characters so real that they take on a life of their own, building an entire world, the political/magic system. Designing all of this is no easy feat. That being said. This book had so. Much. Potential. I was so excited to read this book, and I plan to finish it for the sake of finishing it. But. At this point, I would have set I’d aside as a DNF. The book could have benefited from some form of a developmental editor, or an in depth beta reader. I will say this. Within 5 chapters, there are so many… phrases that I’ve highlight that I’ve latched onto. Phrases about books and storms that were written BEAUTIFULLY! So, bravo Linton for hitting the nail on the head as to why readers disappear like they do! However, 5 chapters in and I can already guess where a majority of the story is going. But that’s also because I read like a mad-woman and have read this particular type of story, many different ways. Enemies to lovers where the FMC isn’t who she thinks she is. I am all about supporting indie authors. BUT. I also feel like criticism should be constructive, and not degrading. So if I could give this book a 4 1/2, strictly because I know the work the author put into this, I would. So if you’re looking for an easy read with characters that aren’t hard to follow, look no further! They are easy to love and easy to care for. One of the biggest issues they lacked, to me, was depth and plausible reactions to their situations. JD, you have done BEAUTIFULLY writing this book. I applaud and will continue to buy your books in the future. My BIGGEST recommendation is to definitely hire some form of an editor for any upcoming books. Or in turn, I will be happy to beta read for you. Should my opinion change of the book by the time I finish, I will happily get on here and say I was wrong, delete this review and post a different one. Until then…

this book set my soul ablaze! <3
Format: Paperback, Format: Paperback
"i had never really cared about the weather before, but now, clear skies meant everything to me, and i was grateful to see another calm morning." this book. this book! i loved the last storm so much. the writing style. the descriptions. the world-building. the characters. the plot twists. the tropes. the sexual tension. the—everything. everything was magic. the last storm follows our two main characters, ara and rogue, giving us dual POV from both characters (which i loved, btw). ara, a human girl who has been locked away in her father’s estate most of her life, just wants to see the world. all she dreams of is seeing what else is out there. but when her father announces her engagement, she knows that dream will become nothing more than just that—a dream. rogue, the fae king, is tired of the attacks being rained down on his people. in hopes of finding out the human king adon’s secrets, rogue infiltrates auryna’s borders. in his last resort to gain information, he visits the local pub. to his surprise, the general’s precious only child is sitting at the bar, drink round after round of mead. now he just needs to figure out how to take her without anyone noticing. first and foremost, let’s talk about the endless list of my favorite tropes and aspects that this book had. ›› enemies to lovers ›› fated mates ›› one bed ›› the chosen one ›› elemental magic ›› actually good and shocking plot twists!!! ›› badass female lead ›› morally-grey love interest ›› fae/human war ›› force proximity ›› touch her and die ›› who did this to you? ›› captor/captive ›› praise k!nk (panting profusely) “you are entirely the opposite of everything that i am, and i would gladly wear your shackles if it meant i could have you.” it’s been a long while since i read a book i liked this much. but i just loved this book. it set my soul ablaze. thank you to the author for writing this beautiful story and for blessing me with an eARC! i loved it so much that i immediately bought the paperback upon release! every aspect of this book was just beautiful. i was blown away by the way the world was described, the way feelings were portrayed, the way the elements were used in the fae’s magic. it just—AHHH! i just absolutely adored it all. i cannot wait for the second book to release next year! also the way he calls her “little storm” sets my heart on fire. this was a fast-paced read and if you are a lover of acotar, fbaa, deal with the elf king, or any other similar books, then please stop everything you’re doing and read this book right now. you won’t regret it. thank you again, jd linton, for giving me the privilege of reading your arc and for blessing this world with the world you created. <3 "something about him pulled me in, like a moth to a flame, and it felt as if i was just waiting for the inevitable burn that came with flying too close to the fire."
