Turn Your Meta Quest 3 into a Giant DJI Flight Display! (No DJI Goggles Required)

Turn Your Meta Quest 3 into a Giant DJI Flight Display! 🚁 (DJI Neo + Quest 3 Immersive Flying)

📌 Video Description

In this video, I'll show you how to wirelessly display the DJI Fly app on your Meta Quest 3 using Tendy.

Simply install Tendy Link on your Android phone, and you can stream the DJI Fly screen directly to the Tendy app in Quest 3. Instead of flying while staring at a small phone display, you can enjoy a large virtual screen inside your headset for a much more immersive flying experience.

No expensive flight goggles are required—just your Quest 3 and an Android phone.

---

💡 How It Works

🕹️ DJI Fly remains in full control.
Your flying workflow doesn't change. Continue flying with the DJI Fly app using the touchscreen or, for the best experience, a DJI remote controller.

🥽 Quest 3 becomes your giant virtual display.
Tendy Link wirelessly mirrors your phone's screen into Meta Quest 3, allowing you to fly while viewing DJI Fly on a large floating display.

🌐 More than DJI Fly.
Screen casting is just one of the many features supported by Tendy Link. You can also mirror many other Android apps to Quest 3.

⚠️ Important Notes

• This solution uses wireless screen mirroring, so a small amount of latency is normal.

• It works well for casual flying, hovering, aerial photography, cinematic shots, and flying in open areas.

• It is not intended for high-speed racing, freestyle FPV, or flying through tight obstacles, where ultra-low latency is essential.

• This is not a replacement for DJI's dedicated flight goggles, but an affordable way to enjoy flying on a giant virtual display.

Couldn't find a way to cast my phone to Quest 3... so I coded one myself!

 

A lot of people have been searching for a way to cast their phone screen to Quest 3.

Honestly, so was I.

As a drone pilot who loves FPV, I had one simple wish when I got my Quest 3: I wanted to fly my DJI drone while wearing the headset, putting the live camera feed right onto a massive VR screen.

I searched everywhere but couldn’t find a smooth, reliable solution that worked for me.

So, I did what any developer would do—I built one myself.

That’s how Tendy Link (Phone Cast) came to life.

But to be completely honest, once I finished coding it and started testing, I realized its potential goes way beyond what I initially imagined. It’s not just about checking notifications or watching YouTube anymore. The real magic is: It brings the entire Android ecosystem seamlessly into Quest.

My mind is already racing with all the fun things we can do with this:

🔹 Flying a drone with DJI Fly inside Quest 3 (Next video topic!)

🔹 Driving FPV RC cars with a giant VR viewpoint

🔹 Hooking up a digital microscope for massive macro visuals

🔹 Doing close-up cinematic camera movements with Gunpla models...

I truly believe that sometimes the best projects don't come from market research—they come from a pure desire to play and experiment.

If this tool that I built just for fun happens to help other Quest 3 players who share the same pain point, that makes it even better.

This video is a quick walkthrough and submission demo of Tendy Link's vertical and horizontal casting modes. The app is currently going through the review process!

🎬 COMING UP NEXT:

In the next video, I’ll be dropping a full hands-on feature of the "DJI Fly VR Big Screen" experience! If you want to see what it's like to fly a drone inside Quest 3, make sure to subscribe and hit the notification bell so you don't miss it!

Quest 3 終於可以看手機了！Tendy Link 將 Android 畫面帶進 VR

 

很多 Quest 3 用戶一直希望，可以把手機畫面顯示在 VR 裡。

其實，我也是。

我是空拍機玩家，很喜歡 FPV，一直很想戴著 Quest 3 操作 DJI Fly，把手機畫面放到 VR 的大螢幕中。

找了很久，都沒有找到真正符合需求的方法。

所以最後，我決定自己做一個。

這就是 Tendy Link Phone Cast。

一開始只是想解決自己的需求。

真正做出來之後才發現，它的用途比我想像的更多。

除了查看手機畫面之外，它還可以應用在：

DJI Fly 空拍機 
遙控車
顯微鏡
模型拍攝（像鋼彈運鏡）
更多 Android App

很多以前只能盯著 6 吋手機螢幕做的事情，現在都可以直接在 Quest 的大螢幕裡觀看。

注意：Phone Cast 是將手機畫面同步顯示到 Quest 中，並不是遠端操作手機。操作仍然是在手機上完成。

這支是送審的影片 https://youtu.be/bw-tgvn92wI

 下一支影片，我會分享 DJI Fly + Quest 3 的實際體驗。

那也是我最初開發這個功能的原因。

如果這個功能也正是你一直在找的，希望它能對你有所幫助。

歡迎留言分享，你最想把什麼畫面帶進 Quest。

我只是一直想把更多世界帶進 Quest，而 Tendy，就是為了這件事而誕生。
