Just found this DJI Inspire case, putting it here to remind myself as much as anything. http://goprofessionalcases.com/shopcases/dji-phantom-cases/dji-inspire-1-landing-mode-case.html The case that comes free with the Inspire is good but you have to go through the farce of putting the Inspire in transport mode and detaching the camera to pack it away, and do the reverse to set it up again. With this case you can leave the camera attached and just take it out and fly like with the Phantom 3, and put it away again afterwards without all the messing about. Apart from saving it also means you aren't causing wear and tear and risking breakages on the camera by removing it and reattaching it all the time. If anyone finds any other cases where you can do the same, especially lightweight backpacks, please post them below. Please do not post cases that don't allow you to leave the camera on.
Just found a place in Europe that sells drone cases, including one for the Inspire where you can keep the camera attached. https://mc-cases.com/ Just got this one from them for the Parrot Bebop drone with Skycontroller.
They make a nice looking case for the Phantom 3 which holds the aircraft with the props attached, always a big plus, the price ain't bad either.
