T1 Ranger VTOL no osd O4 pro

hello I'm not sure if I did anything wrong but I wired the Rx from o4 to tx on flight board and tx from o4 to Rx on flight board, but no osd shows up. Is this a problem mission planner can fix and if yes does anyone know what parameters to change?

Can't disarm flight controller.

I am using a Kakute H7 Wing flight controller and a RadioMaster RP2. The problem is that there is a pre-arm check that seems to find a problem, it says "Motors: Check frame class and type" I'm building a single copter a bit like the one in the last photo. I have been able to get the transmitter, receiver and the flight controller to talk to each other. The only problem is that it doesn't arm, I have tried to connect a ESC and motor to see if it will work but it doesn't. In addition the ESC doesn't pass its own check and starts beeping, while the servos stay stationary, but they are powered on.

I would appreciate any help and please ask me any questions if needed. Below is a link to the params. BTW, I'm using ArduPilot and this is my first ardupilot project.

Edit: I don’t aim for horizontal flight. At least not for now.

I built ARES: An open-source, fully autonomous, GPS-denied drone system for planetary surveying using Jetson Edge AI

Hey everyone,

I wanted to share a project I've been working on called ARES (Autonomous Reconnaissance & Exploration System). It's a fully autonomous UAV platform designed to operate in extraterrestrial or extreme remote environments where global positioning satellites are completely unavailable.

Here is what it does under the hood:

  • Fully Autonomous: Takes off, maps boundaries, performs Boustrophedon sweeps, and precision lands with zero human intervention.
  • GPS-Denied Navigation: Relies entirely on visual boundary tracing, optical flow, and AprilTags.
  • Split-Compute Architecture: The aerial vehicle handles real-time flight logic (Jetson Nano) and video encoding, while a companion Base Station handles the heavy Surface Feature Recognition AI (Jetson Orin Nano Super).
  • Edge AI: Custom AI pipeline running at 30+ FPS via TensorRT FP16.
  • Autonomous Charging: Integrated CC-CV Battery Management System via Arduino Mega.

The software stack runs on Ubuntu using PX4 / ArduPilot via MAVSDK-Python, and we've structured the codebase to be production-ready (YAML configs, JSON logging, pytest suite).

I'd love to get feedback from this community, especially if you work with visual navigation, drones, or Edge AI.

Demo Video: https://youtu.be/ioSG0SbZH6A 

GitHub Repo: https://github.com/kalesha681/ARES-Autonomous-Surveyor

If you find this interesting, a star on the repo would be incredibly helpful for the project's visibility! I'll be in the comments and happy to answer any questions about the hardware or computer vision pipeline.

HGLRC M100 PRO orientation for correct compass heading

I have HGLRC M100 PRO GPS module (with compass) physically setup on drone as shown in image right bottom corner (3D printed a little holder so it's a bit farther away from battery and other electronics. Cable wrapped in Cu foil and grounded also with insulating tape around it).

This is the orientation I found also in the supplier docs. Docs also says to adjust Betaflight orientation to CW 180 flip. Since I'm using Ardupilot and not Betaflight, what is the correct setting for GPS orientation in Mission Planner?

I calibrated the compass (outdoors using radio switch to start calibration so I'm far from PC or any other electronics) and it autodetects rotation as Yaw270. That can't be right...

In Mission planner I can also see the drone heading is off (not pointing in right direction on map) and I'm getting pre-arm error: check mag field (xy diff: 218>125). I guess I need to manually set the compass orientation...but what is the correct setting?

Log files show GPS works fine when I fly around (some pre-arm checks disabled to get airborne) and maps the correct flight path.

Help with building autonomous quad (first time trying ardupilot)

Hey guy, i really need help figuring out ardupilot for a 5 inch freestyle drone i have. ideally autonomous drones should be bigger and with lower kv motors as well as other fcs and i understand that, however for just this specific case its a speedybee f405 v4 stack with t motor 2207 2550kv motors. Bascially i just want to be able to trigger an automatic take off , a set path and automatic return to the original takeoff spot. that is all i require. futhermore, i would like to give these commands via an single board computer running linux on it. Kindly tell me if it is possible or not , and it would be of IMMENSE help if someone could help me out with it. i have this drone and i have to get it running autonomously within a few days for a competition . specs are :
speedybee f405 v4 stack , flysky reciever and transmitter 10ch ,t motor 2207 2550kv motors, gep m10 gps and a 5 inch frame.

having issues with CoreWing F405 WING V2, no supported ardurover firmware

i'm working on a USV using the corewing f405 wing v2 but there is no supported ardurover firmware for it, i've tried using the matek f405's firmware and speedybee's but both have problems either with the IMU (speedybee) or the barometer (matek) does anyone have experience with this board? will i be able to run ardurover on it or should i just buy another one?
matek firmware:

https://preview.redd.it/n5fsky7ospih1.png?width=437&format=png&auto=webp&s=63b9db354e9fe40b01e8f8cf6b65cde87af463ad

speedybee firmware:

i know the board is not defective or anything since i was able to run inav firmware on it and make an rc car out of it, today ill probably try to do waypoint missions with it since it has gps.

heres my entire components list:
Flight controller stack

  • CoreWing F405 WING V2 (flight controller board, top plate, and PDB PLUS, running as a set)
  • CoreWing Wireless USB Extender PRO (came with the stack, not yet used for telemetry)

Receiver and RC link

  • Radiolink R6FG receiver (individual PWM outputs per channel)
  • ESP32-WROOM-32 DevKitC clone, with a CP2102 USB-to-UART chip, used as a PWM-to-SBUS bridge

GPS and compass

  • Walksnail WS-M181 (GPS over UART, compass over I2C)

Firmware and tools

  • INAV Configurator, current firmware setup for the rover
  • Arduino IDE, for the ESP32 sketch
  • SBUS library by Bolder Flight Systems, for the ESP32's SBUS output

Radiomaster Mrk III with CRSF Protocol, ELRS

Everyone, I have no clue what I am doing for what I need to get. I have a Radiomaster TS16X Mrk III that has an internal protocol of CRSF. I what to build a drone that supports the internal protocol and ELRS. i have no idea what to focus on as far as the receiver, controller, etc. I am looking to modify an existing FPV build (fixed camera) and add a gimbal camera and make it long range. I have the mentioned radio. I need the components.

Mesh network radios

Hello guys, I am building a drone swarm where I want mesh based communication between all my drones. I see in India that exicom is one company that sells for high ranges and bandwidth. Can someone please recommend other options as well? Also, what's the pricing of exicom radios for my application, if you may know?

Looking for drone pilots (with Docker/K8s experience) to beta test a live MAVLink tracking proxy I built! 🚁💻

Hey everyone,

I’ve been working on a live drone tracking project and I'm currently looking for some beta testers and potential partners to help me improve it.

What I built: I created a lightweight proxy designed for live drone tracking. Essentially, you send your drone's MAVLink telemetry to this proxy, and it seamlessly relays the data packages to my website for real-time tracking on a map.

You can check out the current state of the site here:https://www.ollebo.com(Click on the "Live" menu to see where the tracking happens).

Who I'm looking for: I need a few tech-savvy drone pilots to help me test the pipeline. Because of how the proxy is currently deployed, you will need at least a basic understanding of Docker or Kubernetes (K8s) to get it up and running on your end.

What's next: I’m actively building out the site right now, so any feedback on the proxy, the latency, or the web interface would be hugely appreciated. If you are interested in partnering up to develop this further, I’d love to chat about that too!

If you have a drone, know your way around containers, and want to help test a cool MAVLink project, please drop a comment below or send me a DM!

Thanks!
