HELP ME FIND THE ERROR! Mobula7 o4

Hello friends! . Help me find the problem.

THE PROBLEM:

The image I get out to my goggles from my Mobula7 o4 works at first. I get an image and everything flows as usual. When I press ARMED, the image freezes. The drone works and I can lift and handle it but I go "blind". The image freezes and then stays in my goggles like that until I pull out the battery.

Note that I lost the original antenna that comes with the drone in a crash. The problem started after the crash.

I HAVE TESTED THESE THINGS :

- I have checked and worked with the video transmission cable from the camera to the card.

- I have changed the antenna 3 times.

- I have also changed to an LHCP antenna.

The problem is style there!

What could be the error and what do I need to do?

Thank you for all the help and all the ideas I can get so I can fly my Mobula7 o4 again! 🙏

What are Standards for Voice Controlled Drones?

i have a 8 inch quad running ardupilot. A lidar (30 meters range), RGB camera and Jetson orin nano super on board.

I want one stream of communication, that's between me and jetson through wifi.

I want jetson to tag everything it sees through rgb, and compare it to google earth maps, it will have gps and compass data from Flight Controller, so it shouldn't be a issue. lidar for indoor needs.

Quad should follow commands like , map the red building. or following the car.

I know this is technically possible, as i have seen examples (missiles). robots work the same way, right? but i havn't see voice command widely commercialised in drones.

  • is unnecessary?
  • redundent?
  • Only military needs?
  • unreliable?
  • Computationally Limited?

if i carry on with this project, what are the

  • things i should look out for?
  • what are the limitations?
  • Where should i start from?
  • what is he easy part?
  • will 8gb ram be enough?

I will appreciate any info regarding this. Thankyou

Rate my Build 3”( Pls)

Hello everyone, I'm quite new to drone construction, I built a tinywhoop but it didn't go very well, but now I wanted to try with a 3inch (possibly sub250 but only the frame and components get to 190g😭), I know that the esc will be overkill but I wanted to take it that then maybe I pass it to a bigger drone like an axisflying ban, I also take the vtx and limit it and later I will move it to a bigger drone

I'm just asking if maybe you can tell me if they have mating problems or things like that

DJI really ended Mini series, next 250g drone will be DJI Air 4

There will never be any new DJI Mini 6

There will now be just DJI Lito (cheap 250g) and DJI Air (expensive 250g)

DJI drone line will be simplified.

They just wanted to do Air under 250 grams, thats why DJI came up with the name Lito.

It was impossible to improve Mini 5 Pro anyway, so the 2026 Q4 250g drone will be first ever to include two lenses under 250g.

I'm back, and so are the wobbles

I tightened everything and replaced props. This made a huge difference, but the wobbles are still there although lessened. Here's the video any suggestions as to what to investigate highly appreciated! Thanks yall

Emax BLheli 20A ESC with 5V2A BEC smoked out

Brand new ESC.

  1. Checked for shorts. All good.
  2. Soldered an XT60
  3. Powered up bare ESC using a 3s LiPo. All good. Disconnected power.
  4. Connected BEC output to input of servo tester.
  5. Powered up. All good. Disconnected power.
  6. Connected a 9g servo to the tester. Powered up. Poof 💨 ESC sparked near the bldc motor output🔥

Strange observation: I pulled out the battery within a split second but I could hear the typical startup beeps the motor makes coming from the servo! Hello? This is not normal!?

Now there’s a short between the main power leads.

Checked with a known good ESC. Servo is fine. Tester is fine. Battery is fine.

I am in the right to totally claim for a refund/replacement, right?

Reviving my old MultiWii tricopter project

Hello everyone,

I have an old project I’d like to bring back to life that I started about 12 years ago and never really finished. If I remember correctly, I was using a MultiWii as the controller. I’d like to modernize it and eventually complete the project.

What are the latest flight controllers with GPS and Return-to-Home features that I should look into for a tricopter build?

Looking for advice on drone frame designing

Hi all, I'm trying to design a drone frame for this class I have and was wondering if there were any specific things I should keep in mind while doing so. I've never made a drone frame before, so this is all very new to me. The requirements I have are that we have to take three tennis balls from one platform to the other. The overall distance and height aren't that much, about 200cm in the x direction and 150cm in the y direction.

Right now, I already have all the components chosen, I'm just missing a frame. I've heard that the frame isn't the most important part, especially in my case where I don't really need a perfect drone. But still, I'm trying to make it as good as I can to reduce vibrations, and damage to my components when crashing.

Another problem I have, is that I can't really be using carbon fiber due to time limitations, and rules imposed on us by the professors. So I'd be mainly making it using 3D printing and laser cutting of MDF boards. I was wondering if there would be any recommendations as to what types of materials to use in that regard? I've heard using softer plastic would survive crashing better, but I'm worried about bending and vibrations, same as for the MDF boards.

So I was wondering if you guys would have any recommendations? I've looked at a few open source designs, notably the ones from TBS Source, but I'm still not that sure in which direction to go yet. Any help would be greatly appreciated!
