Just thought I'd post pics of my quad case. It took a while to build but the cost to build it was practically zero. I utilized an old beds plywood and the foam from its mattress.
I have been using it now for about 4 months and I really like it. It's just big enough to securely fit:
- the quad with props off
- extra batteries
- lipo charger
- various powercords, GoPro stuff, extra props...
Dimensions are in cm: 55 x 55 x 24.5
