I'm also a fan of Dusty's idea for air travel. I thought about getting one of the pelicans, but was turned off on the idea of wasting a day to pick and pluck my own foam. Plus I hear, without using some kind of spray adhesive after the pluck process, one can expect the remaining unplucked pieces to continue to dismember themselves over time. The solution of putting the standard case inside a bigger case is just brilliant in the simplicity of the solution.
That being said, I'm using the GPC landing mode case. It is giant. I've been lugging it around on the back of my Maverick. I drilled out the bottom to mount it to some pipe clamps and the roll cage (not featured in the picture) to make it a more permanent attachment to the vehicle. I do wish the case was slightly more robust, as there is a slight amount of flex in the walls and lid that is likely a result of its gargantuan size, but that being said I have put it through some serious stress riding trails. I'm certain what I have put that case and the inspire through amounts to 1000 times the amount of bumps and jolts that they would be subjected to in the context of a single flight, and I haven't had any adverse issues with any of the gear. Of a particular concern was the camera gimbal, but it too has had no issues remaining attached to the Inspire. As an added note, the five latch closures have also worked at keeping the case closed despite all the shaking. That being said, I would definitely throw some locks on there if I were to put it through baggage handling.
