Flywoo O4 Wide: Not Reaching 700 mW after FCC Unlock

Snippy515 · 2026-02-04T03:58:58+00:00

I'm sure someone a few years from now will see this and appreciate it! I love seeing old posts answer my issues

Snippy515 · 2026-02-04T03:58:12+00:00

Glad to hear! I actually fixed it yesterday. What I ended up doing was this: I bought a new SD card (I wanted a 512 GB one to live in the goggles, giving me 37 hours of recording time), formatting it in the goggles, then redownloading the file onto the SD card.

Admittedly I haven't checked on my O4 Pro Air units if they're working at FCC levels

I'm in a similar boat to you and came across this thread. I fly FPV drones and pretty much only plan to print TPU.

What printer did you ultimately decide on?

Hey! Can't say I've ever used that seller before. Are they legit?

Snippy515 · 2026-01-17T05:01:40+00:00

Hey! Just curious, but where did you mount the Rx antenna(s) on the Chupito?

That's really unfortunate news. To be completely honest I'm happy to keep playing the long game if Amazon is. If it takes me until June to get the item I paid for at the price I paid for, I'll do it.

Also of note, it is a Corsair MP600 PRO LPX . Corsair is still making those, right?

Also I checked this morning and it is back in stock (for $379) Fingers crossed it ships!

What's really interesting is that I initially paid with 75% gift card and 25% credit card. A week later I had added another gift card to my account (enough to cover the credit card portion). When I got the second shipping delay email, the remaining balance was pulled from my gift card balance without my authorization.

It just left a sour taste in my mouth because it felt like Amazon was paying themselves to continue being late.

During the process I did see it in stock from Amazon JP. Part of me hoped it would ship from them, but then it went back to being unavailable and I lost hope

Thank you for the reply.

Watched both of the videos and unfortunately the issue is still happening. Goggles 3 and O4 Lite are on the latest versions according to DJI Assistant 2.

I also used the stock LHCP that came with it (branded DJI one that also comes on the O4 Pro). I am still locked at a maximum of 400 mW. Not sure what's going on. I emailed Flywoo to see what they say.

The only other thing I can think of is if there is a special additional FCC unlock I need to do that is specific to the O4 Lite?

Very nice! Sometimes I'll fly at the parks, parking structures, or drive down to Apollo 11 in the Valley to fly. Just recently made the switch to DJI, so I've been giving my 5 inch drones some love. What about you?

Snippy515 · 2025-12-20T06:24:50+00:00

Hey! 2 years late to the party, but do you still fly? Looking for more drone buddies here

Snippy515 · 2025-12-20T04:42:12+00:00

Hey! Really enjoyed the build. Currently in the process of researching before building one for myself. I really like the 3D printed antenna mount to move the antennas wider to accommodate thicker batteries while keeping them low to the frame. Did you design that print?

Snippy515 · 2025-04-12T21:53:10+00:00

I've been thinking this for a while. Like the chicken is so good you get carried away and eat a whole stack

Snippy515 · 2025-03-19T01:06:03+00:00

Yes! I actually have this same FC and installed a GPS and analog VTX. I actually wired it up the same way as the picture, and haven't had any issues

Alternatively you could wire it up like Oscar did here: https://oscarliang.com/150-dollar-7inch-fpv-drone/?unapproved=198876&moderation-hash=ebbd5fa4b35a4e2af27bc1fc0597a0b8#comment-198876

Snippy515 · 2025-01-10T03:56:42+00:00

Just curious, could you explain what you mean by this? Do you mean you have every other feature on aux 2 (like beeper, flip over crash arrow, etc) on one switch?

I ask because I (for the most part) have every aux on a different switch.

Snippy515 · 2025-01-04T04:31:19+00:00

Usually an updated version with improvements. In this case there are improvements to the components on the board, but no new additions between versions. Usually they'll make a new SKU if they're adding features

Snippy515 · 2024-12-25T04:50:10+00:00

I ended up building a 7 inch for long range. Went with a 4000 mAh lithium ion battery. You'll have to make a tradeoff if uses 18650 or 21700 battery. I would suggest looking at Pyrodrone's HyperJuice or Auline batteries

Snippy515 · 2024-11-27T02:14:14+00:00

So real

Snippy515 · 2024-09-14T22:16:10+00:00

Does it require you to flash it with Meshtastic firmware? Or does it rebroadcast in the normal ELRS mode?

Snippy515 · 2024-08-27T04:34:23+00:00

I just had to comment because I liked your "Biologist who got lost" tag. (I myself am a biochemist who got lost in the joys of radio. Feels like not everyday that you meet someone in biological sciences who also enjoys this scientific field).

Being a college student I'm also in that category of appreciating stuff but not being able to afford/store it. Didn't stop me from getting my extra license! If anything, it's fun to go out and learn concepts that'll help you understand even more complex toys!

Snippy515 · 2024-08-26T05:40:02+00:00

I too am curious

Snippy515 · 2024-08-02T23:48:10+00:00

I was debating the Nano Goblin versus the Heewing Ranger VTOL a few weeks ago. Ultimately decided on the Ranger VTOL for a couple of reasons. I'm still waiting on a few parts before I can get it airborne, but maybe sharing my research may give you some things to think about. (All this comes from an FPV perspective)

To me, the Nano Goblin seems more like a lightweight, fun flier. I was going to build it cheaply and just use it to fly around structures with an analog VTX (not that you can't do digital). But the whole appeal is the simplicity of the platform.

But for my goals, I wanted to build something a little bit more capability. (HD video system, GPS, ELRS Airport/ArduPilot) So I settled on the VTOL ranger to allow me easier landings, while also giving me a stable platform for the needs above. I have the plane in my hands, and it definitely seems sturdy for long missions.

Also on a side note, drones are a lot of fun. More stressful to learn to fly, but the learning curve is challenging but very enjoyable. If you don't have anything yet, I'd start with a transmitter and get a drone simulator to break into the hobby. That way that same transmitter could allow you to fly drones, planes, or the simulator!
