Got the draknight 2 from hglrc everything is solid and can't wait to fly gonna put some sim time in before I take it out.

I made sure to take out the sound so you should be good

Almost finished building my drone.

I use BN-220 GPS, the issue is that Betaflight does not see the GPS which remains with a gray Icon.

Also the GPS switches on the red led for few seconds then it stops, while the blue led keeps blinking.

What to do?

I’m attending THR drone / low-altitude economy expo tmr in Shenzhen.

It is MASSIVE: around 110,000 sq metres of exhibition space, some 1200 exhibitors, 10,000 products on display. The show covers the full low-altitude economy / unmanned systems chain, including:

Consumer and civilian drones

Industrial drones

FPV / drone racing / drone soccer

Drone components and supply chain

Motors, optics, engines, navigation, comms, image transmission

Mapping, surveying, inspection, emergency response, agriculture, logistics

Low-altitude infrastructure

AI + robotics

Anti-drone / counter-UAS systems

eVTOL and general aviation

Single-person flying vehicles

I have an engineering/software background working in Canada, but relatively new to drones. I want to understand what’s actually useful from a business/industry standpoint, what has potential vs hype.

For people who fly, build, work with, or follow drones: what would you be most interested in seeing from this expo? Any specific companies, or types of drones would be of interest?

Also, would anyone be interested in having on-the-ground scout for a day? I could look for specific products, manufacturers, pricing, catalogs, contact info, or general market observations while I’m there. I speak fluent English and Mandarin.

In any case, I will share some photos and general observations afterward! So let me know what you would like to see!

Cheers 🥂

Is it normal for it to be this crooked? Thanks in advice

I have nearly all the electronics parts for a 16" inch drone. However I'm missing a frame, but I'm a lil too cheap to buy a 16" kit from AliExpress.

Would it be possible to build a reinforced version of a standard x frame out of PVC pipes? (please consult my high quality drawing above.)

I understand that PVC would have to be rather thick not to bend, but I don't image it would be that detrimental to the flight performance. + I'm not really looking for a top performing drone.

My question is this, has anyone ever attempted something like this? I could only find little 7-10inch drones made from PVC nothing this big?

Is there anything I have failed to consider?

Thank you in advance,

Doc.

Cant wait to get my license and fly this thing :3 I am planning on building my own custom o4 quad later on. I have officially been consumed by this hobby loool

Looking to build my first drone. Have plenty of practice on my Vision40 tinywhoop. Wanting to have a 3” drone with moonlight for 4k for dabbling in long range with a 3000mah lion pack and recording chasing model airplanes. Some light freestyle but nothing crazy. How’s my parts list? Anything stick out?

I am losing my mind from this darwinfpv f405 stack, was just about to hover test the drone but it kept flipping out. Checked the setup 3d model and just realized this. I have been trying to figure it out since morning and it still won't budge, I've tried changing board orientation and checking board arrow but no change. Does any of you ever have this same problem or maybe have a fix?

Hi yall, bought this speedy bee f405 aio v2 40a without realizing it was mainly for tiny whoops. The question is, can I use it on my 5in build? Running 2207 2600 kv motors. Help a chud out please :)

Hi everyone, I’m new to FPV and I’m having a serious issue with my BETAFPV Air75 II Champion.
The quad started having vibrations, and while trying to fix it I accidentally reset all the settings in Betaflight. Since then, I’ve been stuck trying to recover it.
Now I’m running into multiple problems:
The CLI dumps/presets from the BETAFPV website don’t work on my version (I get “unknown command” errors)
The VTX seems inconsistent (on USB I only see OSD, and video behavior is strange)
When I arm the quad, it immediately shoots straight upward uncontrollably
The drone is an air 75 II champion btw and I can see the osd but nothing is there other than that I did just see the vtx antenna came loose because of a crash but how do I fix this after that I tried with a preset I found but still doesn’t work what’s wrong
Overall settings seem completely wrong after the reset
I’m still a beginner and I’m not sure what I messed up or how to properly restore it. I’m worried I’ve broken something in the configuration.
If anyone has a BETAFPV Air75 II Champion (especially stock or close to stock), could you please share your Betaflight CLI dump or correct factory settings? Also any advice on how to properly restore it on newer Betaflight versions would really help.
Thanks a lot in advance.

I've been using my 3" 04 Pro cinewhoop to fly at these trails for the past year or so but this weekend I broke it on my first pack. I brought my 3.5" 03 cinewhoop along as backup. First I tried running a GoPro on it but after building the muscle memory flying these trails with a 250g quad it just wasn't happening. So I said fuck it and, even though I didn't have any ND filters for it, just went with the 03 footage.

Turned out pretty good IMO! Would have been even better if I hadn't forgotten I was on 2K and 120FPS all day. Whoops.
