We won't be able to fund this project as, for the solder you'll click an option saying that you need a solder when you submit, and for the RC Transmitter, that's an expensive pre-made item that is not allowed to be bought. Instead, try making it yourself!

Made BOM.csv and updated README.md & Planning

Journal Entry 7 – Project Setup & Control System Planning

Date: 25,December,2025 (Day-8)

Today was mostly about setting things up properly instead of jumping straight into building or flying anything.

I finalized the basic project structure and documentation, including the first BOM.csv for Phase 1. For now, I’m only focusing on the transmitter and receiver. The goal is to understand how RC signals actually work before dealing with motors, batteries, or anything high-power.

I also made the first version of the quadrotor frame CAD in Fusion 360. This isn’t meant to be a final design. It’s more of a reference to think about layout, spacing, and how things might come together later. I expect this CAD to change a lot once I start testing electronics and figuring out real constraints.

Next, I want to power the receiver separately and connect it to a PC so I can start looking at raw channel data. From there, I’ll experiment with things like channel mapping, signal stability, latency, and how failsafes behave when the signal drops.

No flying planned at this stage. I want to reduce unknowns and actually understand what’s going on before moving forward.

Thanks for reading.

So you need a BOM.csv in the project's root directory as well as images of the cad and any eletrical stuff inside the readme. thanks!

Created the assembly frame CAD!

Today I've received a reply from the grant I've requested from Kai

"Hello, I like the project idea, but you need to include a full CAD assembly of your project :D This means designing the entire thing before making it!"

I really appreciate your feedback and i understood that i would require to make an cad assembly for my project so as Kai asked I've made an full assembly main-frame CAD for my Drone-Project so that it is what i did today. It was pretty hard since i'm still new to Fusion360 i've watched some tutorials and read some of blogs to learn and research about making CAD files and i've finally made one. Btw the design i've made is intentionally simple and not production-level type of design as development progresses changes may occur. and the final product may vary significantly from this design.

Okay thats it. Thank you for your feedback.

Also I've made an more detailed journal entry on my github repo (journals/day-6)
you can check it out for understanding the journal entry more detailly.

Overall this took around 5-6 hours.

Software used: Fusion360
Also one more thing you can find the stl files of the 3D models i've made in the repo:
cad/assembly

ill also upload them below:

Current status on the project!

I’ve been recording my journals and work directly in the GitHub repo under the journal folder, so you can see everything there. I’ve written journal entries across about 5 days, and I’m adding an estimated total time spent here. This isn’t just the time spent coding, but also planning, documenting, debugging, and understanding how everything works.

Overall, it took around ~25!

So far, I’ve been focusing on understanding how drone control systems work, especially how transmitter input turns into data, how receivers communicate using iBUS, and how that data can be read and logged safely on a PC. I also set up the project structure, wrote multiple journals, and built small scripts to read, log, and analyze receiver data without using any motors or flight hardware yet.
