I've got several cases but this is the one I've settled on. It's called Dacckit. It's a rigid case with much nicer padding then most. $40 on Amazon. It holds 4 batteries, charger, receiver and of coarse the Air.
I've modified it by adding slots and areas for my tablet mount and 4way battery charger. The iPad mini fits nicely inside the zippered compartment along with extra sets of props, screen shade protector, extra cables and some paperwork. There are four slots for SD cards and seven slots for other accessories. I do usually use a landing pad because I almost always take off in the dirt. That's the only other thing I have to carry.
