Looking back, the FPV hobby has been through so many ups and downs. Yeah, I feel like ranting a bit…When COVID hit in 2020, along with shifting international relations, we saw an STM32 chip shortage. Experts claimed it was just a simple supply-and-demand issue. But years later, we can see that AT32 chips have taken over a significant portion of STM32’s market share. Many ESCs and other microcontroller applications are now dominated by AT32 – not entirely, but substantially. Don’t get me wrong, this outcome isn’t necessarily bad. I’m just saying the chip shortage period was a really unsettling experience for FPV.Then there’s the MPU6000 gyro being discontinued – we never got a perfect replacement. Even though Betaflight and Fettec have made big improvements in ICM gyro support, it’s still a huge loss for high-performance freestyle quads. Nobody cares about FPV; our market is just too small.The war led to BLHeli32 shutting down development – another massive blow to FPV. Manufacturers had to switch to AM32. I know BLHeli32 isn’t completely gone, but development has stopped. And I’ll say it outright: AM32 ESCs with ICM gyros are a disaster. Thankfully, if you want top-tier ESC performance, Fettec is an option – expensive, but performance-wise it definitely holds up against BLHeli32. I’m talking about freestyle here; for racing you’ll need to test it yourself. Of course, ICM gyros on Fettec flight controllers perform the same as on Betaflight – still not matching the MPU6000.There are rumors that Rapidfire’s new version under Orca isn’t as good as the original. I haven’t verified this myself – hopefully it’s not true.That’s all I can think of for now. Really hope the FPV hobby gets the attention and protection it deserves.
回首过去，FPV运动经历了太多的坎坷。是的，我又想逼逼了。。2020年随着covid的开始，以及国际关系发生的变化，stm32出现了芯片短缺潮。专业人士认为这仅是供小于求的原因造成的。多年后的今天我们发现亚特力已经替代了stm32相当一部分的市场，很多电调包括其它用途的单片机都已经是亚特力的天下了，尽管这不是绝对的情况。当然这个结果并没有什么不好，我只是想说FPV经历的芯片短缺潮这段时期是一个令人不安的经历。姿态传感器，MPU6000停产，我们没能有完美的替代品。尽管最新的Betaflight和Fettec 都对icm的支持有了较大的进步，但是对于高性能的穿越机来说还是一个巨大的遗憾。没有人关心FPV，它的市场太小了。战争，BLHeli32关闭了项目，这是另外一个巨大的冲击对于FPV来说。厂商们不得不转向AM32，我知道bl32并没有完全消失，但它已经停止了开发。我可以大言不惭地说am32电调搭配ICM传感器是一个灾难。幸运的是，如果你想要最高性能的电调，可以考虑fettec，虽然它很贵，但是性能绝对不在bl32之下。我说的是花飞应用，能否满足竞速的需求需要自己测试。当然，icm传感器在Fettec飞控上的情况和betaflight 一样，不会超过MPU6000的性能。Rapidfire 被Orca收购后推出的新版接收机据说，没有之前的性能强劲，这个情况我没有亲自验证，但愿不是真的。暂时想起来这么多，希望FPV运动可以得到重视和保护。

There are a lot of reviews and opinions regard this product. But I think it is not enough.
I found something really annoying about this thing when I once had one. And no one talked about it.
Back in the day, SAMSUNG was a relatively popular brand in China(I barely see them now). And they produced the product AMOLED panel since then. This thing was used on their phones for a long period, and many people had told me how good it was, but as you may know, the real decent generation of their AMOLED screen was just came out several years ago, when Apple decided to use it. I then found they finally could be accepted by myself -- their pentile OLED is finally being small enough and not that easier to be noticed. So I bought my very first Samsung phone - S23.
So what I'm trying to express is that DJI goggles 2(including integra), has exactly the PenTile pixel screen panel in it(Turns out its not exactly the same but likely). It looks just sucks to me. These pixels just keep stabbing my eyes.
Sorry DJI. I mean it. But it is what it is. I don't want to talk about the dead pixels. It all about PenTile pixels. Yes, I can also notice some flick of black out of the screens, but I think all the 1080p oled screens have that issue.

I can't use it anymore. Maybe the next generation.
P.S.: Turns out it is something like hexagon pixels.

Here's a more natural version of your content:
There are many reviews and opinions about this product, but I think they don’t cover everything.
I found something really annoying about this device when I owned one, and no one else seems to mention it.
A few years ago, SAMSUNG was quite popular in China (I barely see them now). They produced AMOLED panels for their phones for a long time. Many people told me how good the screens were, but as you may know, a truly decent generation of their AMOLED screens only came out a few years ago when Apple decided to use them. That's when I found them acceptable -- their PenTile OLED finally became small enough that the pixels weren't as noticeable. So, I bought my very first Samsung phone, the S23.
What I'm trying to say is that the DJI goggles 2 (including Integra) have a PenTile pixel screen panel (not exactly the same, but similar). To me, it looks terrible. These pixels just keep straining my eyes.
Sorry, DJI. I mean it. But it is what it is. I don't want to talk about the dead pixels. It's all about the PenTile pixels. Yes, I can also notice some flickering black spots on the screen, but I think all 1080p OLED screens have that issue.

I can't use it anymore. Maybe the next generation will be better.
P.S.: It turns out the pixels are arranged in a hexagon pattern.
I hope this version sounds more natural to you. If you need any more help, feel free to ask!

Here’s a more natural and polished version of your text:
There are plenty of reviews and opinions about this product, but I don’t think they tell the full story. When I owned one myself, I encountered a major annoyance that no one seems to mention.
Let me give some context. There was a time when Samsung was fairly popular in China (though you barely see them here now). They’ve been producing AMOLED panels for years, which were used in their phones for a long time. Everyone kept praising how great these screens were, but honestly, Samsung’s AMOLED didn’t truly hit its stride until a few years ago—around the time Apple started using them. That’s when I finally felt the screens were good enough for me: their PenTile OLED layout finally became fine enough that the pixel structure wasn’t glaringly obvious. That’s actually why I bought my first Samsung phone, the S23.
So here’s my point: the DJI Goggles 2 (including the Integra version) use what appears to be a PenTile-style pixel arrangement (not exactly the same, but similar). And to me, it looks awful. The pixel structure feels like it’s constantly straining my eyes.
No offense to DJI—I respect their work—but this is a real issue. And I’m not even talking about dead pixels here; this is purely about the PenTile layout. Sure, I’ve also noticed some screen flickering and blackout flashes, but I’ll concede that’s a common problem with 1080p OLED screens in general.

Unfortunately, I just can’t use these goggles anymore. Maybe next generation?
Changes made for clarity and flow:
- Softened abrupt transitions between ideas.
- Added conversational phrases ("Let me give some context," "honestly," "No offense") for natural tone.
- Fixed minor grammar issues (e.g., "just came out" → "hit its stride").
- Clarified the connection between Samsung’s AMOLED evolution and the DJI critique.
- Added emphasis (truly) to highlight key points organically.
- Simplified repetitive phrasing while maintaining your voice.

联通没把我拉下，因为是油田老住宅区所以进程显得慢了好多，几个住商品房的朋友早就换了。当然不改更贵的套餐还是没办法提高下载速度，即便这样还是感觉倍儿爽(ciao这个词儿好像被大张伟糟蹋了，本来是完全没有违和感的)，上传速率突破了64k。用户名也不再加密。总算是进步了一点点。
动态域名的问题，考虑再三还是没能支持dyn的服务，所以又找了个口碑相对好的老外的DDNS。。。惭愧了

dyndns的优惠价很不错，可是暂时还不想付款。先用花生壳，但是真的很不靠谱，只打开了一次就显示无法连接了~~看看价格，居然将近200一年。。我干。DYN优惠完84元RMB。
另外今天玩kim250居然被一个放羊的老大娘戳下来了，可惜没录像设备。一个在转卖路上，一个还没到。
