  • E-flite 4-Site 3D FF RC Airplane Introduction

    In the early 2000s, "flat foamy" models were extremely popular because they could be scratch-built from foam sheets you could buy in many stores. Today, most foam models are fully moulded sport and scale aircraft – and few can match the unique capabilities and performance of flat foam models, especially those designed and built for aerobatic plus 3D flying! The E-flite® 4-Site 3D FF (Flat Foamy) 800mm is based on the original F3P and UMX models and is a biplane alternative to the popular Eratix 3D FF that's taken the market by storm. It's perfect for experienced pilots who already build and fly flat foam models, intermediate pilots who are interested in them but don't want to undertake a complicated build, and less experienced pilots who have always wanted to try but were intimidated by the extra effort and skills required to buy, build and fly such a model. The 4-Site 3D FF is the easiest to fly, most convenient, and best value in a biplane flat foamy model yet!

    E-flite 4-Site 3D FF RC Airplane Overview

    The E-flite® 4-Site 3D FF (Flat Foamy) 800mm offers the aggressive aerobatic plus smooth sport and slow-flying performance of similar class models – without all the hassles of buying components for and building one! It bolts and snaps together so it can be ready to fly in less time than it takes to charge a battery compared to the glue, tape, and many hours it usually takes to assemble other "flat foamy" aircraft. It's a biplane alternative to the best-selling Eratix 3D FF with a shorter wingspan but more wing area for lower wing loading overall. Its lightweight yet extremely durable EPP airframe is mostly factory-assembled and includes three durable and precise metal-geared servos on all the control surfaces. The factory-installed power system features a 3S-compatible brushless motor matched to a Spektrum Avian Smart ESC compatible with Smart and non-Smart 850–1000mAh batteries. The BNF Basic version is also equipped with an AR630+ receiver to deliver real-time telemetry data, enhanced AS3X+, and optional-use SAFE Select technologies. It's small enough and light enough to be flown indoors in gymnasiums and other similar spaces or outdoors in yards, parks, and sports fields, making it a versatile addition to the hangar for a wide range of pilots!

    E-flite 4-Site 3D FF RC Airplane Features

    • Receiver loaded with a Smart Transmitter File that allows you to import all settings for NX and iX series transmitters during the binding process
    • The unmatched stability and locked-in feel of exclusive and enhanced AS3X+ technology
    • Compatible with the Spektrum DXS transmitter included with many of the most popular E-flite® and HobbyZone® trainer airplane models
    • Extremely durable yet lightweight, high-density EPP airframe with carbon fiber and composite reinforcements
    • Factory-finished in a high-contrast, high-visibility trim scheme for excellent orientation
    • Three factory-installed metal geared and digital servos for all control surfaces
    • Fast and easy assembly unlike similar class models – no glue or tape required
    • Landing gear snaps into place for easy installation, removal and replacement
    Skill Level 2 – Some Experience Required

    Skill Level 2 aircraft, like this one, are suitable for RC pilots with the experience and skills to assemble, set up, and fly similar class models. Although the 4-Site 3D FF is easier to assemble and fly than other flat foamy models, it's not a suitable first-ever RC aircraft for new pilots or a first-ever aerobatic/3D model for low-time RC pilots. You should have the experience and skills necessary to successfully fly aerobatic models like the E-flite UMX Ultrix, UMX Timber X, T-28 Trojan 1.1m, Sportix 1.1m, Timber X 1.2m, or other similar class models before attempting to fly the 4-Site 3D FF BNF Basic version.

    Exclusive Technologies

    This BNF Basic version has exclusive Spektrum AS3X+ and SAFE Select technologies. Enhanced AS3X+ technology works behind the scenes to smooth out the effects of wind and turbulence and deliver an even more locked-in feel than standard AS3X, which makes it seem like you're flying a much larger airplane. Optional-use SAFE Select offers pitch and bank angle limits and automatic self-leveling that can be turned on and off at the flip of a switch! If you don't want to enable the SAFE Select features, simply bind the receiver normally, and only AS3X+ will be active. The receiver is also loaded with a Smart Transmitter Model File that allows you to import all the settings for NX and iX series transmitters during the binding process to be ready to fly in less time than ever!

    Smart Technology

    The 4-Site 3D FF is equipped with an exclusive Spektrum Avian Smart Lite ESC that can provide a variety of real-time power system-related telemetry data including motor RPM, current, overall battery voltage, and more – with Smart and non-Smart batteries – via compatible receivers (including the AR630+) and Spektrum AirWare equipped transmitters (including the DX6e and DX8e, DX6 G2/3 and DX8 G2, the DX9, NX6 to 20, iX12 to 20 and others) while you fly.

    Uniquely Capable

    Like other flat foamy models, the 4-Site 3D FF is capable of slow cruising, smooth sport flying, basic aerobatics, and even aggressive 3D flying—all in the same flight! It offers a truly “mild to wild” flight experience that intermediate to experienced pilots will appreciate, whether indoors in gymnasiums or outdoors in yards, parks, sports fields, and beyond.

    High Performance

    The factory-installed brushless power system features a specially tuned Spektrum outrunner motor. This power system delivers plenty of thrust for unlimited vertical and 3D performance with 3S 850–1000mAh batteries!

    Easy Assembly

    Unlike other flat foamy models that are only available as kits without power and control components, the 4-Site 3D FF arrives mostly factory-assembled with the power system, servos, and receiver (BNF Basic version only) installed. All you need to do is finish some quick and easy final bolt/snap-together assembly—without the use of glue, tape, or special tools—and you'll be ready to fly in less time than it takes to charge a battery!

    Durable Design

    Three factory-installed digital servos with metal gears on all the control surfaces, plus construction with carbon fiber and composite-reinforced, high-density EPP, deliver a lightweight yet stiff and durable airframe. In the unfortunate event you damage any airframe parts or components and can't repair them, a full line of replacement/spare parts is readily available.

Interesting. Confusing ending that's too similar to another book
Ok, I had to process almost a whole 24 hours before I could write this review. And long story short, did I enjoy the book, yes. Does it have a lot of interesting and good parts to it? Also yes. But does it also have some major flaws? Absolutely. Now I'm not gonna break down every single little thing in this book. But here are the basics of what I liked, and what I didn't like. The good? I liked the characters. They intrigued me off the bad. The world building is pretty decent. It's a little confusing in the beginning, but information is slowly doled out, and some questions are answered. I found that there was a lot of little twists and turns that kept the story engaging. The magic system is intriguing. But, there are quite a few things off for me. First off, we have another story that has heavy inspirations from other books. There are a lot of aspects in this story that felt directly pulled from throne of glass. And the big twist at the end? Was almost verbatim the same ending as the book how does it feel. As soon as I read it I was like hold up, I literally just read almost this same thing when I read how does it feel when it released like a year or year and a half ago. Now I know no concepts are really new anymore, and inspiration comes for everywhere. But I feel like most stories it's like, oh this book has these vibes, or if you liked this book you'd like this one that's similar. But this reminds me of powerless in where there are like exact plots and plot points taken from other things. Now is that a bad thing? Not necessarily. I still enjoyed powerless, and I still enjoyed this story. But it does throw me. There are also a few red flags that the MMC Acker gave me that were not the good kind of red flags we love. First, when they are riding thru the city and people throw stuff at the FMC and he does nothing? Red flag. When they meet his dad and they demand she vows not only to the king but to the MMC? Red flag. All the secrets he keeps? Red flag. When he SLAPS HER IN THE END? Red flag. I'm not sure how I really feel about him. In the end. This was still an enjoyable read. I did like it and I am curious about the next book. But I am wary about some of the plot points and the MMC.

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.
