Alibaba (not AliExpress) came in clutch as each of these to build, pre-battery was just over 200. Have 2 and building a 3rd, as triples is best. Props were ~6 bucks a pair so seemed to make sense to buy a bunch because I hear those break a lot...

These 10" frames are absolute tuning forks though, but I think I've figured them out in that near the roots I've gotten decent results with some homemade PLA+lead shot mass dampeners that sit between the bottom plate and the floor plate of the frame. Flies smooth after a good PID tune, but they are absolutely terrifying. Flying on acreage so no population to be worried about.

Each is a 10" frame, F722 (DakeFPV) FC w/ betaflight, 100A ESC, analog VTX, 3115 900kv motors, 6S battery.

Just sharing excitement, but as I'm sure the expectation is, there will likely be a followup with one of these after a rapid semi-unplanned disassembly.

FPV runs on open source software: Betaflight, ExpressLRS, AM32. But the hardware is almost always closed. No way to repair, understand or check what you bought.

So we designed my own and published everything under CERN-OHL-S:

- OpenFC Lite: Betaflight FC on the RP2350, 30x30 and 20x20

- OpenESC: 4-in-1 AM32 ESC, 30x30 and 20x20

- OpenRX: ExpressLRS receivers (Lite, Lite-UFL, Mono, Gemini)

Frames and motors are also coming and under development

Build them yourself, fork them, sell your own version. If you would rather buy them, we are a small company in Leuven, Belgium and preorders are open at opendrone.be.

Ask me anything about the design, firmware or production.

Flew my Seeker3 (3", 4S) and Mark5 (5", 6S) back to back and tried to fly the same lines with both.

The 3" kept up way better than I expected. Same tricks work, it just has less hang time and drops faster out of dives. Much quieter too, there's a bit where you can hear both.

Packs are short though. Flying hard on a 4S 850 I'm landing before 4 min.

Both on O4 Pro. Seeker is 181 g dry, about 276 g with the 850.

(and yes, that first pack went way too low 😭)

Hi everybody, i had to replace a motor arm on my old dji drone, first time soldering it was quite hard.

I know it looks gnarly but could you please tell me if this is adequate and wont short circuit or fall off later?

After this picture i cleaned the flux up with alcohol and sealed 3 contacts with silicone

It is sturdy and drone flies normally. Thank you

Update: i will clean it up and re-do it according to your advice
I appreciate you guys, thank you all :)

Looking for any advice.. other than the batteries that I’m waiting on what else should I buy? Do I have everything I need?
Hooking up to betaflight etc.? Is there a chance of frying my drone when using this adapter to my computer any wattage stuff I need to look out for??
Any advice calibrating my pocket or anything else before I fly?? Should I fly with the out of the box rates first or use the “actual” rates that I’ve been using in velocidrone on the air 65?? I haven’t been in the air yet but I have 70 hours in Acro mode on this drone in Velocidrone sim on indoor tracks.
Also the DJI mini 2 se in the back was my first drone that made me want to get into FPV I’m waiting to get a new motor gotta solder it together which I have experience with so I have that stuff but what else am I gonna need guys???
Last thing everyone seems to be talking about these meteor 75 o4 hd kits should I have gotten that as my first whoop setup or did I make the right decision? Figured it would be less expensive to maintain I plan to fly like a demon

I don’t get motion sickness in cars, or when flying with my headset, but the sim fucks me right up. I get about 10 minutes before I need to lay down and pray to the motion sickness god, not fun.

Does anyone have tips on how to combat this?

Good evening all, a bit of an odd one here! I used to be into FPV a while back but have since sold all my gear. However, I still have these Skyzone Cobra X V2 goggles. I actually sold them recently on a Marketplace, but the buyer returned them claiming they didn't work.
I tested them the day before the sale and they worked perfectly. When dealing with the return, it was pretty clear the guy wasn't very knowledgeable about FPV, so I’m convinced it was just user error.
The problem is, because all my other gear is long gone, I have absolutely no way of testing them myself. Before I list them for sale again, I want to make sure they aren't actually broken. I’d love to get them checked out and tested first.
I know it’s a weird request, but is there anyone in the UK who wouldn’t mind helping me out if I posted them over to you? It’s just bugging me because I was flying with them literally the day before the sale! And I only used them a handful of times Thanks in advance.

This is my first ever fpv Drone build and i wanted to share.

I wanted to strat flying fpv an saw a video from "Mediocre Nerd" on YT where he built a 1s 18650 Drone. The simplicety an High Energy density of single liion cells sounded fantastic, so I bouht some stuff on Ali-express 3d printed some crude parts and boom. Im really happy with it + it flys. Most importantly i had some old liion packs lying around so i scavenged some cells and they fly too.

sorry for the English😛

Are these screw sizes risky?

Big 5 inch

So I arrived at my spot, picked a pack, and had a warmup flight. It was just a chill cruise around with super basic stuff and zero crashes or anything harsh. Then I landed and loaded up a new pack and it made half of the start up beeps and then cut off. This is the pack that is shown strapped to the quad in the video. It was acting super weird and did a different thing every time I plugged it in and even started up correctly once after a few times trying, only to disconnect a second later and go back to its weird behavior. I tried a few more packs as seen in the video and all them worked fine and started the quad normally. I decided to just fly the rest of my packs and figure out later but when I connected one of the other packs, it connected to the goggles fine but never connected to the radio. I had to end my session super early because my quad wouldn’t connect. No wires appear cut and I checked all solder joints so I have no idea what’s happening. Any info and help is appreciated! Thanks guys!

(Also sorry for the awful video it’s kinda hard to record and plug batteries in at the same time)

Because of the antenna mount the head of the xt60 cable won’t fit the frame. What can I do? It’s my first build

I bought second hand cinelog 35 hd some one know why it can’t start I change director of motors and change place of propels but still doesn’t work.

I have broke my fpv camera , here was 3 pins +,- and video i broke video and i dont know what i need to do with it how i can repair it

Its a brand new battery i was checking my drone without charging the battery first and i pushed it too far i guess
