I bought the Dronecrates Phantom 3 backpack and it is amazing. The other one I was debating about was the goprofessional Limited Edition Phantom 3 backpack but either way I believe they are the 2 best backpack solutions for the phantom 3. If you need foam for an existing case there is this website that sells the foam for their cases, maybe you could find one with the right dimensions or mod it a little to fit what you already have:The problem is no proper case exists. Getting foam, allows you to buy a real backpack, that has pockets, or fits your personalized needs and protect your drone.
I have the hardshell DJI case, and the problem is there is no pockets on the outside to store tools, filters, iPad, cables, harness and all the stuff you really need. Most of the soft backpacks for sale with inserts aren't great for my needs either. I have a large perfect backpack that I sewed modifications to myself. This will be great for a foam insert.
I think this is why people want to choose a foam insert for customization

that is just one of their foams inserts they sell, there are more available.
