what is the best o4 wide fpv drone for under $330,I am specifaccly looking for toothpick quads under 4" since i want a park/playground freestyle drone

Do you think the prices will flip and make DJI a more affordable option than Walksnail for those outside the US?

Sorry this ended up longer than I want because I dont need to know if one is better than the other, just if any one else also speculates the cost of change will make it more accessible in the future. or have some facts to back this.

Is it worth converting a fleet requiring significant investment?

I went Walksnail early on and paid a lot less than it currently retails for, because they were cheaper and offered better options for sub 250 Drones...about 5 years ago. A lot has changed since. I don't hate the walksnail stuff I actually love it, and don't love a closed ecosystem. I have had several different VTXs, and even my original Avatar PRO VTX that survived a dip in a pool is my daily driver until I kill it. I expect my Goggles X to keep working too...

I also love it when stuff just works, there is so much tinkering in this hobby, its noice to have something just work out of the box. WS stuff is better now for sure, I recently had a GT and it was a lovely bit of kit, it did just work and the range was great. But I am noticing there is increasing parity in price between DJI and walksnail and even the DJI air units being cheaper than Avatar. I shop local when I can but do spend a lot of time investing in Ali express and see it there.

I think it is the restrictions in the US shifting the demand. I fully believe the DJI system is better for range, image and operation, though never used one. I would just try it out but the investment to change is substantial, I have watched a lot of reviews and spent a lot of time on the walksnail stuff getting it to do what it claims. I am at standardizing parts to reduce my building time and increase my flying time so I am ready to choose what is better and available going forward, than what is cheaper. I would love to hear what Aussies have to say.

But if you are limited in choice or have to choose it, I fully rate walksnail, though like ELRS it has a few extra step to get it dialed in but works well when you do.

saving my new sub-100g FPV drone with bare hands!

Hey guys, Walle here from WalleFPV.

Just took our new sub-100g Eagle3 engineering prototype out for its first outdoor hover and motor linearity check today, and well... it turned into a near-fatal flyaway survival challenge! 😂

As you can see in the video, the moment I armed and gave it a slight punch, the high-frequency oscillation went absolutely crazy. Before I could even react, the quad completely lost control and initiated a full-throttled FLYAWAY, screaming and shooting straight up into the air!

To save the fresh Naked DJI O4 Pro camera sensor from smashing onto the concrete or disappearing over the roof, I had to jump and pull off a sketchy bare-hand interception right out of the sky. Luckily, the new custom CNC machined camera guard works great as a hand-hold, the frame is perfectly fine, and I've still got 10 intact fingers to finish the tuning tonight!

The Tech Challenge:

Designing a sub-100g 1.8" True X frame with a Naked O3/O4 setup means balancing weight vs. structural rigidity. The extreme gyro noise on this initial test saturated the PID loop instantly, leading to this sudden runaway.

My plan for tonight back at the bench:

1. Revamp the Betaflight filter settings (sliding up the D-term dynamic filters and tweaking the dual PT1 lowpass).

2. Lower the D-term gains significantly to prevent runaway saturation.

3. Check if the FC soft-mounting is transmitting frame resonance.

Have any tuning gurus here solved mid-to-high frequency resonance causing flyaways on micro 45mm setups without adding heavy carbon beef? Would love to hear your thoughts or filter layout suggestions in the comments!

Proper 4K raw cinematic footage from the O4 will be posted here as soon as I wipe out the gyro noise. Cheers!

Just wondering if you need to solder any thing when installing the o4 wide on this

I'm intending on building a mid-performance durable 3.5inch racer/cruiser.

Does anyone know of any 3-4 inch motors that uses 3mm shafts all the way through? The only ones I know of is FPVCycle, which costs like A$190 to get 5 motors to australia, or it's 1604.5 which is suprisingly way cheaper than I thought - About A$105. The FPVCycle is very attractive but its way out of my ballpark price-wise, and the good 3.5inch racing frames are 9mm mounts so it's 1604.5 which is a 12mm mount isn't suitable.

I'm still looking for a potential good low-drag durable frame that isn't going to break my bank, if its open source I could ask a local shop to cut from thicker carbon as an alternative.

I also dislike the long-body form factors found in most freestyle frames where there's an unnecessarily long stack holding the frame and FC. Ideally, the camera should also be well protected, without having standoffs in view.

Currently I'm settling in on 3 frame choices, two of which do not satisfy me design-wise: Crux35 (base plate is a flawed design), uangel35 (as a budget option) and the recursionfpv's scythe, which is probably going to cost a rediculous amount to get shipped over since only cncdrones in canada has the rights to cut them at the moment and shipment from the opposite side of the world isn't cheap. But biggest of all, scythe only has 9x9mm motor mounts, which means if I get them, I'll have to go full ham in on the fpv cycle motors which means just the frame and motors alone is going to cost as much as two air 65s

WalleFPV Eagle3 Prototype - Sub 100g Naked O4 Pro FPV Drone Upgrade

Hello DIYFPV community, I’m Walle from WalleFPV, bringing an update on our Eagle3 prototype, successor to Eagle2.

The core design goal: keep Naked O4 Pro on board while keeping takeoff weight <100g, and fix the weak point of Eagle2 — the protruding camera lens.

Changelog Eagle2 → Eagle3

• New machined camera guard structure, fully wraps the Naked O4 Pro lens, reduces crash damage risk

• Switched to true X frame layout, optimized CG and motor power distribution for more predictable handling

• Compatible with 45mm / 1.8" propellers

• Buzzer fitted as standard

Dual battery choices: 3S380mAh lightweight pack, or 3S550mAh longer runtime pack

Legal note: The sub-100g takeoff weight could mean registration exemption in UK and Japan. This is not legal advice; every operator must check local drone regulations.

Flight testing is underway. Will post O4 raw footage soon. Happy to answer your technical questions below.

Going to do a custom 5in build and for the frame its between the geprc mark 5 or the deepspace seeker5...opinions?

Hey guys,

As my first FPV setup I am thinking about getting this:

-happymodel mobula8 walksnail

-Walksnail Avatar Goggles L

-Radiomaster pocket

I know I still need a charger, batteries (2s I believe), and Some other stuff. I will probably be flying primarily outside, and I want a very budget way into FPV that doesn't lock me into some obscure ecosystem.

If you have any comments please let me know.

Hi guys, I have a question as a beginner getting into the hobby.

Have the wasp major 22.6-6.5 2020kv motors been discontinued?

I have recently broken my motor and i wanted to by another one, but it was out of stock at every online fpv store I knew exept for pyrodrone, but there I have to pay like 60 dollars for shipping. Does anyone know if the wasp major 22.6-6.5 2020kv motors are still in production and if there is any store with EU warehouses were I can buy them?

Im looking to upgrade my goggles, Is the skyzone cobra x v4 worth it? I am looking something with hdmi input,module bay for under 350$ idc if it is box or slim just wondering if those goggles are worth the upgrade to emax transporter 2's

Dose anyone have a mobula 7 v4 frame on hand? I can't find the size of the battery holder thing online. If you have one how big is it?

Anyone have any tip on getting a computer to recognize your flight controller? Betaflight preferably. I had a 10in giving to me and built it out, but can’t setup the FC.

So what are you offering for $200.00

does the Caddx / Walksnail Avatar HD FPV Goggles L have better range and quilty than the betafpv p1 and vo4 goggles

i dont know how to build on the builder but if you want any ideas to get to 250 the Betafpv Matrix 1S Brushless Flight Controller 3in1 would be handy

Anybody using a Oxbot Radio controller? Do you like it - are they good? I was thinking about getting one for my grandson instead of a Radiomaster Pocket.

I bought the Sequre S99 (thanks Joshua Bardwell) from Aliexpress and it came like this. Did I get a fake? Works fine as far as I can tell.

What would be a good stack for a 5" free style build? Is the "Speedybee F405" any good?
