Hi, I started ordering components for a drone that is close to the specs of project Quiver.
It will be a quadcopter. The main goal for me is to get more experience regarding the FC + software and also beeing able to maybe fly some of the attachments that will be developed for project Quiver. This thread will keep track of components+cost and overall progress.

**EDIT 07.11.24:** I decided to use a horizontal folding mechanism for the motor arms. I also ordered some 30mm landing gear adapters, 30mm motor adapters and 4m of 30x28mm carbon fiber tube. I dont think i need the whole 4m, but since the cad model is not made yet i want to have it in stock during assembly. I also ordered a set of Hobbywing X6 Plus for testing compared to the other configuration.
**EDIT 15.11.24:** Added FC, PDB, Compass/GNSS, Transmitter/Receiver (on drone)
**EDIT 25.11.24:** Added Lidar
**EDIT 02.12.24:** Added RPI, Battery, Quick release, Aluminum parts, PCB & Parts; +picture post#1

I think this is a good idea. My only suggestion is to submit it as a grant to the GBC when you have a good definition and projected cost!

ESC is begging for a 3D print housing with cooling fins attached…

This Design will be a little bit different then what we discussed for Quiver.
Main difference is that the battery will be under the main frame, getting the cg as low as possible.
It will feature:
- Main PCB for all components (FC, PDB, Transmitter, GNSS & Compass, connector for equipment adapter, power supply, power switch, battery connector, RPI, mobile connection 4G/5G etc.)
- Slide in battery with connector (no need to attach wire)
- Aluminum sheets and beams riveted together to create strong frame
- Quick connect adapter on the bottom for equipment (Over the time it will be the same one Quiver uses)
- Foldable motor beams
- Motor beams and landing gear are both 30mm diameter tube

@sleety I can’t edit the fist post anymore. Is it limited to 4 edits? Or is it a time thing? I was doing several edits, because i added components over the time

Yes I think so, I guess there’re some default limitations for the main post?

It seems that it has a 30 day edit limit. I am trying to fix this 🤔

Current state of the project:
Things still to do:
- design and print the main lid
- print the small lid that goes in the front over the fuse and connector
- wire up and configurate the FC
- configuration and attachment of other devices like RPI, lidar, camera etc.
At least a first motor test will be done next week I think.
