Designed specifically for use with our Nexus Helicopter Flybarless control unit and compatible with all CRSF/S.BUS enabled flight controllers the RP3-H ExpressLRS receiver comes with a built-in TCXO and an integrated housing design that makes the receiver tougher and ready to mount in modern helicopter frames. With the RP3-H receiver, you can get reliable, stable, and accurate signal reception, which enhances your flight experience and allows for superior performance even in demanding environments. The RP3-H also features an Ext-V telemetry input for compatibility with older ESCs that do not provide battery voltage telemetry via the control unit.

The RP3-H receiver uses the Skyworks SKY66112 power amplifier to increase telemetry performance, the PA provides up to 100mw of telemetry power, and antenna switching for antenna diversity. It is developed around the ESP8285 MCU and SX1281IMLTRT RF Chip, offering Lora and FLRC 2.4GHz RF links that provide incredible range and low latency. With Wifi built-in, firmware updates can be done on your craft without the need to remove the receiver.

TCXO (temperature compensated crystal oscillator)

The TCXO ensures high stability and accuracy in frequency control, compensating for temperature variations. This results in consistent and reliable signal reception, even in extreme temperature conditions. It also reduces frequency drift over time, providing long-term frequency stability and preventing signal degradation. Click here to learn more about the TCXO.

        This was more than I expected...
        Format: Kindle
        So...I finished this book at nearly 2am! It was just that hard to put down. I loved that it's set in the same world as Fates Hollow but in the future. Poor Pandora has been through so much but there's light at the end of the tunnel for her. She finally meets her dad and it turns out he's amazing. In order to help her learn about demon society and how to control her magic he sends her to the Demon Reform Academy. There she meets 2 awesome demons who help her and care for her. She also sadly meets her 3 tormentors. I will say though that while they do bully Pandora they also rescue her several times and defend her. They too have traumatizing pasts and can't see the good that is in front of them. Of course demon society needs to be shaken up too since that's part of the problem. I really enjoyed this read. I teared up a few times throughout the book but I liked the characters and that ending...well it looks like 3 in denial are going to need to grovel hard.

        MUST READ BOOK!!
        Format: Kindle
        I was in a huge reading slump, when one of my favorite authors recommended this book in her readers group (The amazing Marie Mistry 🫶) and I absolutely DEVOURED this book. Now I’m in the club crying about having to wait until December for Term 2! This book is about a girl named Pandora who has suffered a life that nobody would ever wish to have. This book is about Pandora learning how to live, learning about herself and what she really wants. She has a long journey to find out all of these things, but she took the first steps in this book and it was beautiful to read. Some of the men in this book are our dream men, Hunter and Reed 😍 and then we have the men who need some work and who we all really just want to beat up until they admit what they really feel, Skel, Bram and Dexter. But that cliffy was a killer and I absolutely cannot wait until the next book!! You have written an absolute dream of a book Lyra and I eagerly await the next installment in this series!!!

        Just read it. You won’t regret it.
        Format: Hardcover
        This book completely blew me away. I loved every single character—not just the FMC and MMC, but the side characters too, which is rare. In a first book, side characters can feel flat while the focus is on world-building, but that definitely wasn’t the case here. The romantic tension between the FMC and MMC was so good—seriously addictive. The plot itself felt pretty straightforward at first, and the world-building was easy to follow. It even gave me Heartless Hunter / Wolf King vibes… until the last 20 pages. And wow—those final pages. I usually spot plot twists coming, and I thought this one was going to be predictable, but I was completely wrong. That ending genuinely shocked me—I haven’t had that reaction to a book in a long time. I’m already counting down to book two (and that teaser chapter? Absolutely brutal). Just read it. You won’t regret it.

        4 Stars for Now!
        Format: Kindle
        I DEVOURED this book. I was in a huge slump after reading a horrible series right before this but after 3 pages of this book, I was hooked. I read the whole book in 2 days. I think the author did an amazing job at writing an engaging story with an amazing twist at the end. I know many readers feel betrayed by the twist and find the narrator to be unreliable but I feel that the twist was done in a great unsuspecting way. Though I do feel betrayed, I think there is so much room for redemption in the second book! The author also did an amazing job at world/character building. She was able to do so without interrupting the story which is one of my huge pet peeves. A lot of authors build by taking breaks in the plot or dialogue which I find choppy and disengaging but this author was able to build in an engaging way. There was some lack of world/character building but I think that was due to keeping reader in the dark. The world, politics, and characters were all very easy to understand. I found the romance a little lackluster and a bit off-kilter. Some of it was really pushy and rushed which left a bad taste in my mouth. I do hope the author delves deeper into the romance in coming books. The FMC was a breath of fresh air. She was not whiny or stuck-up like most books. She was never afraid to accept help from others but she was still able to shine with her intelligence. Not once did I think she made a poor decision just for the sake of a plot point. She was really easy to like. The MMC could use some work but I think that will happen more in coming books. This is a MUST read, my only advice would be to wait until it is a finished series!

        Need book 2 please :-)
        Format: Kindle
        From the very first chapter, Metal Slinger hooked me and refused to let go. Set in a brutal, metal-bound world where power is carved from steel and survival depends on strength, strategy, and sheer will, this story follows a young woman forced into a dangerous system where control over metal isn’t just magic — it’s dominance, protection, and rebellion. When she’s pulled into escalating conflict and shifting alliances, she quickly learns that power always comes with a cost. The magic system is sharp and immersive without being overwhelming. The way metal manipulation is woven into combat and politics makes every confrontation feel cinematic and high-stakes. It’s gritty, tense, and beautifully layered. The Brynn, our FMC absolutely shines. She’s fierce but not untouchable, resilient without feeling unrealistic. Watching her navigate betrayal, survival, and the slow awakening of her own strength felt earned every step of the way. There’s grit in her fight scenes and vulnerability in her quieter moments that make her deeply human. And the tension? Immaculate. The chemistry simmers under the surface before sparking into something electric. Every reluctant alliance, every charged interaction, every moment of “are they about to destroy each other or kiss?” had me flying through pages. The pacing is relentless — no filler, no wasted scenes. Twists land hard. Stakes keep climbing. And that ending? Absolutely feral. The kind that leaves you staring at the wall for a minute before immediately checking when book two releases. ✨ Gritty metal-based magic ⚔️ High-stakes survival 🔥 Slow-burn tension 🖤 Fierce, layered heroine 💥 A finale that HITS (but cliffhanger!) This is one of those fantasies that reminds you why you fell in love with the genre in the first place. If this is just Book One, I am more than ready to be emotionally wrecked again in the sequel.
