r/drones

So I crashed my DJI Air 3 and I can actually see it sitting about 55 feet up in a tree. I know exactly where it is, but getting to it looks pretty difficult and honestly kind of risky.

The thing is, I already got it replaced, so I’m not sure if it’s even worth the effort to try and recover it. Part of me feels like I should try because it’s literally sitting up there and potentially salvageable, but another part of me thinks it might not be worth the time, cost, or risk of trying to get it down. (Not to mention this was around 68 months ago, so it’s probably very weathered).

Is there a good site to reliably get parts for cheap drones? I picked up a couple of cheap ($100-200 retail) drones at an auction, my plan was to fix them and let my kids or neighborhood kids use them. I have two of them running, but finding parts has been a nightmare. So far every single "1800 mAh" battery I've ordered has been a fake, based on weight and run time, I'd guess they are 600-900mAh at best. I'm working on hooking them up to a load tester to get an accurate number. Finding blades for them has also been a challenge. Both of them I purchased had completely mismatched blades, such as A4 and A8 on the same motor, or A4s mixed with B2s. I'm fairly good with electronics/robotics, but haven't really done much with drones. As I understand it they should all be the same pitch, correct? Ones I've ordered online don't list a pitch, and it's been a very mixed bag, some of them have also been mismatched, and the ones that aren't are usually 1's, which does have the drones flying, but they really seem to be struggling with enough power. I specifically wanted cheap ones so I didn't mind if they got broken or lost, but I was not expecting such a clusterfuck of non-standardization and outright fraud.

Hi everyone,

I’m currently developing a high-load 46V ESC for a drone, and I want to implement an error indication system (like fault alerts, startup tones, etc.).

For my design, space is very limited, so I’m trying to understand the best approach for a compact buzzer solution.

I’ve noticed that many commercial ESCs (like Hobbywing) don’t seem to have any visible buzzer component, but they still produce beeping sounds during startup and error conditions.

So I have a few questions:

What buzzer technique is best for a compact ESC design?

Any design considerations for high-voltage (46V) ESCs regarding this?

Would really appreciate insights from anyone who has worked on ESC firmware or hardware design.

Thanks!

I was lucky enough to get some good shots of these boats tugging along as the sun was setting.

Just need a cheapy, for taking some photos of my house. Looking at e99 or M66 on alibaba or Temu, but cannot find an actual photo or video taken from these? Which is concerning. I know they all advertise it but surely someone has a photo taken from one of these?

As the title states. I’m using the free version of DaVinci Resolve to edit, but every time I try to import files, it says unsupported file type. I’ve used chat gpt, which suggested running it through shutter encoder, vlc media player and through handbrake, none of which fixed the issue. Any ideas? Is anyone else able to edit footage from a skyrover in DaVinci?

My son is working on a project for a club in 9th grade and they are having some trouble. Please read the description below for the problems. Any advice would be appreciated!

My group is building a 7” FPV drone. And the receiver won’t arm the drone or move the value bars in beta flight recover tab. We had an old receiver(radio master p1) that stop working. We replaced with a new one (same one as old receiver). At first it wouldn’t enter binding mode so we put the old receiver again and power cycled it ( what you normally do to put a receiver in binding mode). The old receiver didn’t turn on but when we put the new receiver it turned on and was already in binding mode. We bound it with transmitter( radio-master pocket). However, nothing is happening in beta flight and we can’t arm ( this was all working before the switch of receiver). We tried the basic stuff and flashed the receiver and put a binding phrase. We check all TX and RX connections (currently on TX/RX 4 and UART 4 in beta flight ). We changed the serial RX port to 4 as well. We made sure the receiver wasn’t in boot-loader mode with the radio isolation test and checked the wires with a multimeter.

Hi folks, I'm going to Turkey soon from the UK and would like to take my under 250g (Potensic Atom 2). I would love to know if any of you have done so/could advise me not to. The hope is to carry on with 3 pin charger and 3 batteries.

Thanks in advance

So I plan on taking it next week and was looking to get a DJI mapping, possibly an IR capable model. My concern is putting a bunch of money into DJI equipment (which I realize works now and from what I've read will continue unless something changes). Things like the ability to get parts in the future or maybe the app being banned. I don't put anything past the government.

So, if you were me would you still invest in DJI or look elsewhere even though it's more $$ and much less quality. I'd hate to drop thousands on a DJI not be able to maintain it.

Hi everyone, I’m pretty new to drones and trying to understand how teamwork actually works in real drone operations.

In some drone filming videos, I’ve seen people using communication headsets on set.

But I’m curious about other types of drone work too, like:

• drone light shows
• drone cleaning
• agriculture or industrial drone jobs

How do people usually communicate during these kinds of work in real life?

Do teams use:

• communication headsets
• walkie-talkies
• or phones

If you’ve actually worked in any of these areas, I’d really love to hear how communication is handled on site. Thanks a lot!
