all this talk got me thinking and I ended up going a different direction with my HF case, I use the foam in the HF box in 2 layers, bottom for batteries and little stuff with it's own slot then the top (1.5" ) layer for the drone and controller. The HF foam isn't very stiff so it doesn't lend itself to using the layer like a tray. I ordered some Kaisan foam in 1.5" thickness from Amazon. It's the same type of closed cell foam that comes in the gucci case SD sells. Doing some research it looks pretty easy to skulpt out a shape leaving the thin (for me bottom) layer intact. I plan to use a 1.5 inch thick piece on the bottom with cutouts to hold batteries, cables, charger, filters etc.. and then have a removable layer above it with cutouts for the drone and controller with it's thin bottom layer intact, like a tray. I'm pretty sure I can fit it all in that way, I'll post up pics when I finish it. It it pans out it would add $40 to the cost of the case setup so it's as much as the case and may not be a good option for some of you. There's cheaper ways to accomplish the same results if you're creative.
