Thanks everyone for the feedback on the project. I hope to keep it going and would love to see some PRs.

Just one last thing, if you like the project, the coolest thing you can do for me is let anyone you know looking for a remote developer to hit me up. I am a Ruby-on-Rails developer at heart but would also consider robotics gigs. Thanks!

Yes, from my experience with this project the external antenna is a must. I've update the README with a link to the one I used.

Hi, I update the README with the components:

Hi, thanks for the feedback. I have updated the README with the materials I used:

I bought everything for this kit from aliexpress:

Car chassis: https://www.aliexpress.com/item/32830665408.html Electronic speed control: https://www.aliexpress.com/item/1005007716682815.html Battery holder: https://www.aliexpress.com/item/1005006283625827.html 2 18650 3.6v cells or 7.4v battery pack (I have used both, cells are more flexible for other projects) ESP32-CAM: https://www.aliexpress.com/item/1005001468076374.html (Very important to get one with external antenna and and I used the 170 degree fisheye camera) Bluetooth Gamepad (I used a PS4 controller)

I've never tried running for a really long time but when I was doing testing I would not recharged the batteries for days. I would say an easy 15 to 30 minute. But like I say, I'e never tested. Now I think I will. Thanks

Hi, thanks for checking out the project. I don't really have anything to gauge by like experience with FPV drones but latency hasn't been an issue on my wireless network even with all the other household devices connected. I think the frame rate is mostly limited by how quickly the esp32 can capture images. In my python script I measure FPS and was receiving about 50 fps from the esp32s. I recently bought a travel router that I want to try it with outside the house.
