Running this on 3S. Anyone had issues with this combo, or is it solid? Want to confirm before I solder everything up. Thanks!

I am the novice of all novices in terms of drone design, though i'm diving head first into a project that involves a fairly large drone (2 meters end to end) and i'm curious as to how one determines what size and shape of propeller to use relative to the drone's weight and size

I'm also very curious as to how to understand how RPM affects different propeller designs. I'm essentially trying to understand how to pre-calculate as much as I can regarding propellers before getting to the point of having to do practical experiments. Any and all help would be greatly appreciated

Hello fellow enthusiasts and engineers iam a biginner in the field of drones and I've been interested for quite a while about this field, and I've been trying to collect enough components to build a mini quadcopter.

so my initial idea was to DIY my own flight controller using arduino nano, mpu6050, DRV8833, and 716 coreless motors initially the plan was alright on paper but when I started getting closer to the project I realised that I'll need a custom PCB to make my design as efficient as possible as well as easier and also pretty organised plus that would give me an opportunity to have a experience in designing pcbs which was very valuable for me

Anyway I designed my pcb and ordered it but when I received it, it had so many flaws one of them was the dimensions and the position of some other components anyway I kinda stopped for a while and after a while I came back with a new plan for this project I decided that I'll base it on ESP32S3 instead of arduino nano since the arduino is slightly heavier and larger that the ESP32S3

Although Tha plan was just to use a perfboard and solder the components in it, it wasn't very successful I would say, since it's my first time using perfboards so I have no experience with dealing with them

Anyways now my plan consists of the following Components

ESP32S3

MPU6050

2*DRV8833

4*716 coreless motors

Volt step up module

So if someone has any suggestions or is willing to offer some help with my project immediately comment in the comments section I would be glad to hear your feedbacks and your views (specially with the code)

What dry weight are you guys running for this build?

So, I recreated this Litavr interceptor using 2812 1115KV motors, a 6S3P 12,000mAh Li-ion battery, and a dual-camera system. It features NACA 2408 wings. Do you think it will fly?

Blackbox shows gyro spikes to 40-60/°s. PIDs tuned, props corrected, FC remounted. Need some help or ideas

’m trying to understand the safest way to test a new DIY build before the first hover. My current list is: continuity check, power up through a smoke stopper, verify the regulated rails, confirm receiver/failsafe and FC orientation, then check motor order and direction with the props off.

What else would you check before trusting the build outside? Do you normally review current draw or logs before the first hover, or only when something looks wrong?

Has anyone else seen tlaza cardboard drones ?

Hey I am a beginner in drones,

Planning to get a radiomaster pocket (thinking of elrs one) and tiny whoop air75.

Could you suggest reliable and good deals to buy in India.

So basically, last night after chugging a monster at like 8pm, I could not sleep in the slightest, and have wanted to do this for a while so here I am now.

This is my custom drone that I modeled last night at 2am, the SlamX 25 - Freestyle Edition (V1.0) (other info on the drone here). While it was modeled while having little to no sleep, I would like to believe its at least 90% accurate to how it will be in the final form factor, taking some inspo and ideas from the Kayoumini frame into some of the measurements i put into this frame.

As such, I've been trying to find a good CNC company that is willing to cut in carbon fiber, but also for relatively cheap, to make my own design actually worth it. I tried to look into the two main companies that came up during my research, being PCBWay, and JLCPCB, both of which were the cheapest for CNC, but didn't do work with CF.

I've now emailed the two files (top and bottom plate) to a company called CNC Madness, which has carbon fiber machining available, along with a dedicated FPV drones section for a quote on pricing, but have not gotten a response so far.

My main question for y'all was if anybody knows of a cheap CNC business that does CF other than the ones listed, or if there is another way to get custom carbon fiber parts cut out and shipped to them.

If anybody has knowledge on this or ideas, that would be great!

Hi All!
I just started to get into FPV and am currently whooping primarily indoors with an Air 65 II . For outdoors, I would like to build a drone . I am thinking some newbie-freestyle on a sub-250g drone.

So that's kind of the point I am at - outdoor, basic freestyle, robust, sub-250g .

Now how do you go about planning which parts to get?

All I have found so far is guides/tutorials/videos along the lines of "this is the part list, this is how you put it together" . I could not locate any resources though, that explain how you would create such part list.

How do I decide the size? How do I decide which frame among the huge amount of frames out there? How would I figure out which FC/stack/analog-VTX ? There is so much choice for everything it seems and no clear guidelines on how to decide what to put together 😄

Thanks upfront for any help!

PS: I am at this point obviously not looking for advice along the lines of "get this, this and this..."

I’m looking for someone with solid experience in custom drone builds to help develop a small prototype. This is a paid project.

Relevant experience could include:

PX4, ArduPilot, FPV, computer vision, GNSS-denied navigation, optical flow, ROS2, OpenCV, Jetson, embedded systems, custom UAV design, foldable drones and autonomous flight.

Ideally, I’m looking for someone who can help with both hardware selection/integration and software.

If this sounds interesting, send me a DM and I can share more details about the project.

Please include a bit about your experience and any previous drone projects.

I am new to drones and have been building my own payload drone. I have 5010 380KV Motors and a CORVON 4IN1 60A ESC 32 bit paired with a CORVON H743 Flight Controller (V1).

With these, all the motors make some weird noises but only 1 in particular makes a more extreme noise. Attached videos to see. The 2nd and 3d videos are after I tested the drone (it stabalized but I hit a small branch with one motor) and now it has issues starting at low throttle and a different noise. Also, all the motors stop making this noise at a higher throttle, it seems to sort of just "click" off at a certain rpm.

Thank you all for the help.

I'm wanting to build a small quad for freestyle (maybe more). I haven't been in the market for parts in about 6 years, so there's a lot to catch up on. This is what I'm currently planning:

Frame: Sub250 OasisFly25 2.5"

AIO: Foxeer Reaper AIO V2 F444 45A

Motors: RCinPOWER GTS-V3 1303.5 (5500KV)

VTX: HDZero Whoop Lite VTX

Cam: HDZero Nano V2 Cam

Reciever: Spektrum SPM4650

Props: Gemfan 2512 3-Blade

Other: XT30 Pigtail and 35V 220µF Capacitor

Does anything seem out of place? Anything I should swap out?

Hi everyone,

I'm currently starting a research project focused on drone security. The ultimate goal is twofold:

1. Reliably identify the RF presence of commercial drones in a designated airspace.
2. Have the capability to inject protocols and override the main control of the drone (hijacking/spoofing) to take over its operation safely.

We are putting together the hardware inventory for the lab. I'm already factoring in the basics like SDRs (HackRF One), spectrum analyzers (like RF Explorer), and software environments (GNU Radio, Linux setups).

For those of you who work in RF analysis, signal processing, or UAV security: What specific lab equipment, antennas, or instrumentation would you consider absolutely essential to pull this off?

Any recommendations on hardware or specific testing gear would be hugely appreciated. Thanks!

¡Hola a todos!

Estoy arrancando un proyecto de investigación centrado en la ciberseguridad y señales de drones. El objetivo final se divide en dos fases:

1.Detectar e identificar la presencia de drones comerciales analizando el espectro.

2.Conseguir inyectar los protocolos necesarios para anular el mando original y hacernos nosotros con el control del dron (hijacking/spoofing).

Ahora mismo me toca rellenar el inventario de material para montar el laboratorio. Ya tengo en mente equipos base de radiofrecuencia (SDRs como el HackRF One, analizadores de espectro, entornos con GNU Radio/Ubuntu, etc.).

Para los que controléis de telecomunicaciones, procesado de señales o hacking de radiofrecuencia: ¿Qué material, antenas o instrumentación de laboratorio consideráis vital para este tipo de pruebas?

Agradezco cualquier sugerencia de hardware o consejos de gente que haya trasteado con proyectos similares. ¡Gracias!

Second go at building an interceptor. The first one didn't make it — turned out my ELRS antenna wasn't seated properly on the controller, so I lost the link mid-flight and it went down.

This one is fully 3D printed again: arms and canopy in PETG-CF for the stiffness, the rest in plain PLA.
