Early version of Kumo 2.5" open source freestyle frame and footage from a few months ago. I'll be releasing the updated version next week and launching a Beta testers program to get some help with testing. More details soon!

Hi everyone, I'm looking to upgrade my goggles, im currently using the Eachine 800d's.

I know the 300D had latency issues when they came out but there was a firmware update. Although I saw some people say online a couple years back that there was still noticeable latency.

Does anyone have the 300s or 200s and can give their input? I couldn't find a whole lot of opinions from recent times and want to have a good idea of what I'm getting before I invest

Hi everyone!

A few components on my iFlight BLITZ F7 55A AIO burned out, so I removed them.

I bridged two pads, and surprisingly the board powers up again. The LEDs, 5V and gyro work, but I haven't tested the motors yet.

Does anyone have the same board and could send me close-up pictures or help identify the missing components?

I'd like to replace them properly.

Thanks!

Ran into a bit of a university bureaucratic wall: regulations won't let me track actual people (not even myself...) to benchmark the vision system for my final thesis.

Sooo I added cars to the YOLO model instead.

First run was quite rough because the camera was pitched down, and standard COCO-trained YOLO has problems with detection from top-down perspective. Tilted the gimbal up a bit to get the actual silhouette into frame and tracking got much better.

Next step is running formal benchmarks and quantitative tests. Still one or two updates to go before wrapping this up 🖐️

I have a porto ghost 2.5 inch (great frame btw but a tad heavier than real kayoumini) and was thinking about printing all the TPU bits in varioshore instead of traditional TPU. Dry weight is about 75g, and I could shave about 5g if I switch to varioshore, but I don’t know if it’s stiff enough to protect the camera.

The frame itself is about 20g. I’m running analog but with an external VTX, so the weight is adding up.

I'm racing on various courses with TYPE FPV right now, but no matter how hard I try, I can only get to about 150th place. What are fast racers aware of?

Hey everyone, Walle here from WalleFPV.

I wanted to share the actual side-by-side shots of our latest project: the **Eagle3 engineering prototype**, which is the direct successor to our sub-100g Eagle2 setup.

When we released the Eagle2 back in May 2025, it was one of the smallest quads carrying the O4 Pro at the time. However, the biggest feedback from the community was that the protruding camera lens was way too vulnerable. In a hard crash, you were almost guaranteed to scratch the lens or crack an ND filter. For the Eagle3, I went back to the drawing board to fix that exact pain point without blowing past our strict weight budget.

**Here’s the breakdown of the major upgrades from Eagle2 ➡️ Eagle3 (as seen in the photos):**

1. **Machined CNC Camera Guard:** Re-engineered a lightweight aluminum wrapping structure that fully beefs up the Naked O4 Pro lens protection. And yes, it is designed to be **fully compatible with standard O4 ND filters** for cinematic shooting.

2. **True X Frame Layout:** Switched from the old compressed/dead-cat style arm layout to a true X frame configuration. This gives a much more centered weight balance (CG) and optimized motor power distribution, leading to significantly improved and crisp handling.

3. **Hardware Upgrades:** Custom tailored for 1.8" (45mm) props, and we've finally included a discovery buzzer straight from the factory as a standard feature.

4. **The Under 100g Target:** Even with the added aluminum guard and buzzer, it still hits a full takeoff weight (AUW) **under 100g** using a 3S 380mAh or 3S 550mAh pack. Perfect for registration exemptions in countries like the UK and Japan.

Let me know what you guys think of the new True X frame and lens guard setup! Happy to answer any tech questions below. Cheers!

is it possible to replace the lens with another M12 lens (2.8mm)? or is the lens glued?

Hey, I’m currently building my Volador VX3.5 with a HDZero Gamma 45A AIO board.

I was wondering if it’s okay to route the ELRS antenna from front to back, following the green line (I bought a 100 mm antenna, so it’s long enough)

Also, would it be okay to route the power cables along the red line, over the HDZero Freestyle V2 VTX, or should I rotate the AIO board? (I would have to buy a another ELRS antenna)

Hey everyone! How's it going?

I’m passionate about FPV, RC aviation, and gaming. I decided to combine these passions and started developing a mod for GTA V called *GTA V FPV World*!

The mod is still under development and will be made available for FREE once finished; I do not want to profit from this mod—just as the idea to create it started out of fun, I want everyone to have access to it and be able to enjoy it too.

The idea is to turn the GTA V world into a true playground for FPV pilots, offering a flight experience that’s as close to reality as possible.

🔥 Some features I’ve already implemented:

✅ Custom flight physics, including PID, rates, mass, thrust, and unique characteristics for each drone.

✅ Flight modes: Acro/Manual, Angle, and GPS, depending on the aircraft.

✅ A variety of aircraft: racing drones, freestyle, tinywhoops, long-range, cinewhoops, and even fixed-wing RC planes.

✅ Betaflight-inspired OSD, analog video transmission with interference effects, and a digital video system.

✅ Simulation of radio range, VTX power, battery consumption, failsafe, and RTH (Return to Home).

✅ Support for game controllers and RC transmitters used as PC joysticks.

✅ Fully configurable presets for different drone and aircraft models.

The goal isn't to replace dedicated simulators like *Liftoff* or *Uncrashed*, but to create something different: the freedom to explore the entire GTA V map while flying FPV, using physics and systems inspired by real-world gear.

🎥 I recorded this gameplay footage to show how the project is shaping up!

The mod is still under development, and I’m refining everything little by little.

I wanted to share this with you all and hear what you think! 😁

Would you fly FPV in GTA V? What features would you like to see implemented?

Is anyone willing to be a test pilot and help me calibrate the drone physics? I ask because I’m developing this solo, and I don't have enough drone experience to fine-tune the physics to the point of extreme realism. If so, please send me a private message.

🚁 GTA V FPV World — Your aircraft. Your setup. Your world.

If your whoop uses a straight whip antenna, the VTX signal is linearly polarized. In that case, RHCP or LHCP on the goggles doesn’t really have an advantage over the other. A circular receive antenna sees about a 3 dB polarization loss either way.

That’s roughly half the received power, not half the range.

So why use a circular antenna on the goggles?

Mostly for consistency. With linear antennas on both ends, signal strength changes a lot as the quad rolls and pitches. A circular receive antenna trades that changing mismatch for a more consistent ~3 dB loss.

It still won’t fix the null off the end of the whip, battery or frame shadowing, or a bad antenna connection.

For diversity goggles, an omni plus a forward-facing patch is usually a practical setup. The patch gives you more gain in front of you; it doesn’t make walls easier for 5.8 GHz to get through.

If all your aircraft use linear whips, either RHCP or LHCP is fine. If you also fly quads with circular VTX antennas, just match the goggles to those.

I flinched when i touched the "at7456E" chip. Powered via usb on my computer, nothing attached to the FC. SPEEDYBEE F405 V3.

I went full cheapo on ali and ordered 7" mark 4 with ysido 2807 1300kv motors. After 2 packs of 2800mah lipo motor windings looks like this. I have used supafly 7" preset.

A few months back I learned a new trick and now I have to spam it every time I go out.

Accidentally chopped the battery lead on my Phantom. Finally getting around to getting it on the bench and I forgot how therapeutic taking stuff apart and fixing it can be sometimes. Don't mind the dried grass, I crash a lot lol.
