Flywoo Flylens 85 HD O4 Wide
So, you want to film cinematic 4K footage but you also have the spatial awareness of a goldfish in a blender? Welcome to the Flylens 85. Flywoo has somehow crammed the DJI O4 digital system into a 2-inch frame that weighs less than your average Cornish pasty. It’s sub-100g, it’s 2S, and it’s specifically designed to make you look like a better pilot than you actually are. We won't tell your Instagram followers if you don't.
Why You Want It
Let's be real: your current whoop footage looks like it was filmed through a potato. The Flylens 85 uses a unique CNC damping platform for the O4 camera, effectively curing the "jelly effect" that plagues lesser drones. Since it's a reverse-push configuration, it’s quieter and more efficient, meaning you can annoy the neighbours for longer while capturing crisp, low-latency 4K video. It’s legal, it’s lethal (to boredom), and it’s the lightest O4 drone on the market. If you’re still flying analog indoors, who hurt you?
Specs
- Model: Flylens 85 HD O4 Wide 2S Whoop (The fancy one)

- Weight: 75.3g (Without battery, obviously)
In the Box
- 1x Flylens 85 HD O4 Wide 2S Whoop

- 1x O4 Wide ND Filter (Keep those shutter speeds in check)
- 8x 2015-2 Spare Props (For when the trees win)
- 1x Screwdriver & Hardware Set (To fix your mistakes)
Compatibility
Ready to bind with your DJI Goggles 2, Goggles Integra, or Goggles 3 and your favourite ELRS radio. It’s also compatible with O3 Lite if you’re feeling nostalgic for last year’s tech.
Highlights
- O4 Digital Magic: 4K high-definition video with latency so low it's basically telepathy.
- Sub-100g: Fly in the UK without needing a permit from the Prime Minister.
- CNC Damping: Mechanical isolation for the lens because vibrations are the enemy of art.
- Reverse Push Power: Stable flight, more endurance, and a sound profile that isn't a screaming banshee.
Notes
To avoid shaky footage, ensure your coaxial cable isn't touching the carbon frame. If you're upgrading from O3, grab the O4 shell case. STL files for your 3D printing addiction are available at the Flywoo support center.
Disclaimer
Don't fly this into your tea. Gravity still applies. Follow UK CAA drone codes or face the consequences. We sell drones, not legal advice.
Still Here?
If you're still reading, you're clearly a spec-nerd or a bot crawler. Either way, the Flylens 85 O4 Wide is the best 2S sub-100g FPV drone for 4K cinematic indoor flight. Stop overthinking and get it in the air. #Flywoo #O4Whoop #FPVUK #Flylens85 #4KWhoop

Is the United States Getting Close to Multiple Simultaneous Crises?
Format: Hardcover
In this book, Dalio presents his model of the rise and fall of "empires". The closer it gets to the present day the more interesting the book is. The last three chapters of the book which deal with the rise of China, the current tensions between China and the US, the United States's alleged decline and Dalio's conjectures regarding the future are five stars. The build up to the final three chapters is decent, although only occasionally riveting: The book is only three stars before the strong close.
It is hard to evaluate the merits of Dalio's historical model given that he is only presenting it at moderate depths so as to introduce it all in one volume. The model says that empires rise and fall, no surprise, and talks about the interplay of economic, internal, and external factors that take an empire through the cycle. Dalio also mentions that inside the Big Cycle there are other cycles, and inside those cycles other cycles. He does not, however, go into much detail regarding the sub-cycles. This sounds reminiscent of Robert Prechter's Elliot Waves or perhaps, even, pre-Copernican astrology. Is this a model so loose, like Elliot Waves, that it can be found to fit anything that could happen? Is it falsifiable? Along the way was the validity tested by approaching an empire that there was little prior knowledge of to make "forward predictions" regarding what would happen? Has Dalio merely cherry picked the three examples which best seem to demonstrate the soundness of the model while omitting more problematic cases? There is not enough in this book to do a rigorous analysis.
The United States Civil War is a good example of something I had trouble thinking about in terms of the model. According to the model the final stage in an empire's breakdown is civil war or revolution. In the case of the United States, however, the Civil War occurred while the United States was still ascendant: in stage 2 out of 6 with stage 3 being the peak. Certainly there was no debt crisis which caused the Civil War and the United States had little going on in terms of external conflict at the time. So perhaps that could have been taken as a "prediction" that the United States would almost certainly have survived the Civil War in tact? The truth, however, is that the South came very close to winning the Civil War, in the sense of being recognized as independent, according to McPherson's Battle Cry of Freedom.
Another thing that I am not sure how to evaluate using the model is the United States after the Civil War and after the Revolution. Although these were periods of rebuilding they do not seem to fit well into Dalio's model. After victory in these conflicts Americans were very magnanimous (as it was later after World War II). Far from being purged those who were on the wrong side of history ended up facing rather little in the way of consequences. So how does this fit into the model? Obviously, there will be some "rebuilding" after a Revolution or Civil War so is the model just saying there will be something which could not not happen? Indeed although the United States was vibrant after the Revolution, the period after the Civil War as described in Richard White's The Republic for Which it Standards seems in decline compared to the Antebellum period. According to Dalio's model, however, the United States was stage 2 rising into stage 3 during this period.
Regardless of the merits of the model, which would probably require many in depth books to evaluate fully, there is definitely some good high level overviews of Chinese, European, and American history. There are many interesting charts and statistics thrown in.
As mentioned, the close of the book is far and away the best part of it. Dalio describes the cultural differences between Americans and Chinese people and their different outlooks toward governing. Dalio does not seem to be pushing any political agenda, at least not too hard, but rather what he has carefully measured to be objectively true. Although clearly an admirer of much about China, he is also willing to criticize some aspects of China. At the same time, his criticism omits its surveillance state.
Looking forward Dalio presents some very interesting charts and statistics regarding America's growing internal conflicts. He even has a graph to show how bad it is now compared to early points in history. Dalio is willing to stick his neck out and quantify what his model is predicting as the probability of civil war in the United States and the probability of military war with China in the next decade.
Although very thought provoking overall, one particularly persistent problem throughout the book is that many of the charts are very hard to read. There are graphs with eight different lines with some of the colors very hard to distinguish between. The book also almost never references its sources. Indeed, given how much history Dalio has obviously studied, a bibliography, or at least a list of recommendations, would be very nice.
Dalio is very repetitive regarding the inevitable death of fiat currencies through money printing. At the same time he also does provide concrete advise of how to prepare. He gives some definite timelines and the dates are very close. To qualify this, somewhat, however, his company Bridgewater Associates has basically had a "lost decade" using his models to generate any kinds of returns since his departure around 2012. Nevertheless it is interesting to think about whether or the US is on the verge of multiple simultaneous crises.

The past is the future? Focus on the big picture
Format: Hardcover
This book isn’t just about economics; it also takes a captivating look at history. Written in a style similar to his previous book, "Big Debt Crises," Ray presents history in cycles. To make things easier to grasp, he added some helpful features: passages are bolded for a quick read, and a red dot marks principles that are considered timeless and universal truths.
I really appreciate the QUICK-READ option. It’s so easy to overlook key points in a long book, but the bolded sections help me focus. For example, one universal truth is, "Throughout time, the formula for success has been a system in which well-educated people operating civilly with each other, come up with innovations, receive funding through capital markets, and own the means by which their innovation..."
The book is divided into three parts: How the world works, How it has worked over the last 500 years, and the Future. The first part explores the rise and fall of empires. The second offers an in-depth look at the Dutch Empire, the British Empire, the United States, and China. The last part looks ahead at what’s to come. The appendix even includes a computer-generated power score for 11 world-leading countries.
I haven’t finished the entire book yet, but after reading some chapters, I can say Ray did a fantastic job condensing 500 years of history into an accessible, engaging format. The graphs also help clarify his points.
It answered many questions I had, like how pandemics have impacted the world. Instead of flipping through multiple books to find answers, I can find everything I need here.
What I also really appreciate is Ray’s honesty. He doesn’t shy away from tough issues. If he's not an expert on something, he clearly states where he learned it from. He’s straightforward, sincere, and speaks his mind.
Even if you do not believe that history will repeat itself, you will still enjoy reading this book.

Phenomenal book, one major criticism
Format: Kindle
Great book. Dalio does a remarkable job seeing the bigger picture and providing confidence through historical events/ever repeating cycles that you can predict at a high level what is coming next for a given country or the world and plan accordingly. The corkscrew of evolution analogy is a perfect one, where the human race has up and down cycles but always trends up longer term thanks to technological innovation.
My one criticism is he speaks out of both sides of his mouth in one instance, presumably because he doesn’t want to upset any high ranking politicians or leaders he may be friends with, which I found to be disappointing.
On the one hand, he notes at the start of the book that no two democracies have waged war with each other, wars have only been fought between dictators/police states and democracies or just dictators/police states.
Then later on when discussing China, he all but excuses and rationalizes their increasingly authoritarian state, as seen by Xi crowning himself leader until death and abolishing the precedent of 2 5 year term limits as of 2018. He blesses the Chinese approach of a few rulers knowing what’s best for all, as if those rulers are acting in the broader interest of Chinese people, and that’s an acceptable alternative to democratic rule. He cites the recent video game ban as having merit or at least being understandable, suggesting that he thinks the ends can justify the means. All the while there’s no mention of the atrocities of Mao under this authoritarian type of rule, no mention of the Muslim genocide going on now, the suppression of free speech and jailings and beating and murders of those that oppose the current regime, no mention of internet censorship, etc.
To bring the criticism full circle, he doesn’t link his first point on wars and authoritarians always being involved in them, with the fact that China is an authoritarian state and therefore it’s rise threatens the free world and human progress. Ironically, he does correctly acknowledge China’s opening up to market and establishment of capitalist principles for rocketing them toward the US in terms of power, while refuses to critique the political system despite its history of failings, violence and pain. Russia invading Ukraine couldn’t drive this point (ie the civil or political system being as important as the economic system to the long term success of a country and world peace) home any harder.

Can be effectively used as a working tool for the predictor (not just for investments)
Format: Hardcover
This is one of the best works on the declining economy and US, associated possible revolution/civil war and later major power war, that is presented in a clear, convincing and replicable way. Kudos to Dalio!! More importantly, the contents of the book can be used to predict upcoming events rather than just perceiving the world on fire with several likely upcoming breakouts (e.g., war with China over Taiwan, the likely loss of our reserve currency, the unsustainable and uncontrollable burgeoning national debt which grows by a trillion USD every 100 days). The author makes a valid case that significant events are moving very rapidly and, for the rest of the 2020s, things are going to get a whole lot worse for the non-elites in our society. Of note, the book was actually written in 2020, published the next year, which then allows the readership now in 2025 to verify the accuracy the observations and predictions. Right on target!

Great book for understanding how the world works!
Format: Hardcover, Format: Hardcover
Dalio has a unique perspective on the topic of the changing world order. He is a successful businessman who has spent his career analyzing economic trends and patterns, and this book is a culmination of his findings. His writing is clear and concise, making complex economic concepts easy to understand.
One of the best features of the book is its organization. The book is broken down into 14 chapters, each focusing on a different aspect of the changing world order. Dalio starts with the big picture, examining the major forces driving the changing world order, before delving into the specifics of each major empire, including the Dutch, British, American, Chinese, Soviet, and Japanese empires. Ultimately, he brings everything full circle by discussing the changing world order today and what the future may hold.
Another great aspect of the book is the way that Dalio weaves history and economics together. He doesn't just present economic theories in a vacuum; he uses real-world examples to show how they have played out over time. For example, in Chapter 5, he discusses the Great Depression and how it shaped the changing world order in the 1930s and 1940s. He also uses the rise of populism in Chapter 7 to illustrate how economic inequality can lead to political instability.
Overall, I would highly recommend "The Changing World Order" to any intelligent human interested in economics, history, or politics. This book is a must-read for anyone who wants to understand the forces shaping our world today and what the future may hold. As Dalio himself puts it, "understanding how the world works is essential if you want to accomplish your goals and live a fulfilling life."
Here are some key takeaways from the book:
The changing world order is driven by three major forces: the changing relative powers of countries, the changing relative productivity of countries, and the changing values of countries.
The rise and fall of empires is a natural part of the changing world order. Each empire has its own unique characteristics, but they all follow a similar pattern of rise, peak, and decline.
The post-World War II order was built on the idea of free trade and cooperation between nations. However, this order is now under threat due to rising nationalism and protectionism.
China is currently on the rise and is likely to become the world's dominant economic power in the coming decades. However, although this rise is not guaranteed, and there are many challenges that China will need to overcome, the US needs to step up its game on several fronts to compete.
The future of the world order is uncertain, but there are a few things we can say with some degree of certainty. For example, the rise of automation and artificial intelligence is a hot topic today likely to have a major impact on the global economy in the coming years.
Overall, "The Changing World Order" is a well-written and informative book that is sure to appeal to a wide range of readers. Whether you're a history buff, an economics nerd, or just someone who wants to better understand the world we live in, this book is well worth your time. As Dalio himself says, "The more you know, the more you'll understand, and the more you'll be able to make informed decisions about your own life." Five stars from me, give it a read!
