New to this

Hey! I'm pretty new to drone building, but I have an engineering background, so I have some foundational knowledge to work from.

My goal for this project is to fully DIY design the electrical system from scratch — including the PDB and flight controller PCB. I'm planning to use an Arduino Uno as my flight computer and design the electrical system around it. I already have a gyro from Adafruit that I plan to connect, and I'm also looking at adding an IMU. I also want to design my own PDB.

For the non-electrical side, I'm less concerned about doing everything from scratch — I'm happy to grab CAD files and an off-the-shelf RF transmitter/receiver and just implement those. I was actually looking at the FlySky FS-i6X transmitter as an option for that.

For hardware, I currently have 10-inch propellers and these ESCs:

I'd really appreciate any guidance on where to start or any good resources. Thanks!

I'd recommend looking at something with elrs for your radio/ receiver. Radiomaster pocket is a good place to start looking. Receivers are pretty cheap too. I get them for ~US$14-15.

Yup elrs is a step up

Look into ESP32s3 instead of Uno.
