Genuinely don't know why I was trying to trippy 4" off the ground

Frame: Sologood Apex evo clone
Fc/ESC: SpeedyBee f405 v5 ox32 stack
Motors: Iflight XING2 1855kv 2207
VTX: Dji 04 Pro

Title says it all, LOL. Happy flying.

Changed ESC right before this flight, setup made it a bit tail heavy, and I forgot to check it, dead calm weather, too slow and wing stall into death spiral. Minimal damage luckily.

Hi guys! I recently completed my first build, a kayoumini with DJI O4 (O3 lens mod).

It flies good, but one thing that bugs me is that it has noticeably less range that my Meteor75 pro 04. Is it really just an effect of having a carbon frame + battery placement? Or do you see any glaring issue with antenna placement?

Happy to hear your opinions or anecdotes!

I would like to connect a gps to the board but I don’t see how I could do it in addition to a vtx and elrs rx. Would it be possible to remap some things to make it work? Any help apprecheated.

Same

My tower antenna broke off, if I snip off the u.fl connector on this radiomaster elrs antenna and solder it to the pad outlined by the black line on the board, would that work? Or should I just do the 3.1cm copper enamel wire fix? Also, if I do go that route, would some copper wire from an old 2005 size motor do the trick?

I purchased my first quad as untested spares/repairs to try and get it working. Managed to grab this Nazgul for ~£100 with an air unit which seems pretty great!

The seller didn’t know much about quads, but knew what it was the Nazgul, not currently working and was happy to let it go for cheap as long as it would go to a good home (a relative passed away and they were selling their possessions).

Yesterday it arrived so spent the day working on it and I believe I’ve got everything up and running - but I’d like to fit a GPS - theres a shielded copper cable that wasn’t attached to anything (it came with GPS and receiver missing).

1. What is this cable likely to be used for? Should I use the shielded cable for the GPS? Does it matter?

2. I’ve currently configured the drone for a DJI transmitter - should I install something like ELRS?

3. Is it worth “tuning” the drone? Will it make a difference?

4. The drone comes with LED strips built in - only the front side of these work (they’re on the arms, sides, and front). I don’t know much about electronics but if I swap the leds over to the other side of the board the same LEDs will work (suggesting the strip itself is broken?) Does anyone have advice on how to fix this?

Thanks!

i know ive seen something similar but i still
cant figure this out. please help. i am getting rx loss with my humingbird v4 and radiomaster pocket. i checked the antenna and it looks fine to me. what should i look at next?

After encountering this problem myself with a really solid commercial BNF drone - the GepRC Vapor X4 - I like so many others began looking for a firmware update or setting that would correct the problem. The closest I found was Justin Bainbridges workflow to remove the gyro data and use visual tracking instead (described here https://www.youtube.com/watch?v=w8imPl0sZ_o).

This convinced me that the issue is indeed corruption in portions of the gyro data. Instead of throwing it all away, I decided to look for a way to simply clean up the bad data. 

An afternoon with Claude proved to be shockingly productive. I started by getting it to extract the gyro data to a csv file just to take a look at the data. Sure enough - I could see impossible spikes in rotation rates in areas where the footage was "bad". I then got claude to re-inject massaged csv files back into the MP4 - easy enough. Finally I prompted it to analyze the data, pointing out timestamp areas of corruption, and design filtering approaches. A few iterations of that produced surprisingly good results - I was then able to load the patched video into Gyroflow and, using just default settings, out came very much improved video. Not perfect, but much much better.

I've sent the code over to the Gyroflow team - not sure if they'll do anything with it (they may have legit licensing reasons for not), but who knows.

Of course the "proper" fix should come from DJI, but in the mean time I'll be using this.

If you're comfortable running Python and would like to try this out, here is the repo: https://github.com/gmatocha/DJI_04_Air_Unit_Gyro_Patcher

Side note - I've been a software engineer for decades. I've "vibe coded" a few times and haven't been impressed. But this was different. I know nothing about how gyro data is stored in MP4 files. In two hours this was solved. No hallucinations - each iteration worked. No agents running in VMs - all through the browser. I swear this isn't an ad.

Doing my first swap
Esc is blueson a2 and the fc is a axisflying f722 eco
Does the plug seem to be correct or should I just direct solder?

I need some help setting the correct settings.

I have been flying with the setting below. (Different from photo)

Packet rate: 250hz - 333hz

Telemetry: 1:64 - 1:128

Switch mode : Wide

Link mode: Normal

Before you says this is a question for google, I don't understand what any of these setting actually do. I have read it and still don't understand what they do.

Im flying at a local air field and I got "RX signal low" in a wide open field, with zero trees.

I am trying for the best settings to get better at freestyle. But I am losing rx signal and I can't figure out why. The blue ○ is where im at in relation to my quad.
