Looks like a nice sturdy case. I used to use a hard case to pack my QX7 but ditched it for a dedicated backpack that has room for the transmitter and fatshark goggles.

I went with the LowePro Quadguard BP X2 and love it. Has room to also carry batteries, tools, props, gopro, etc...and a 5" quad with props off inside. You can also strap 2 additional quads to the outside. Protects the goggles, transmitter and gimbals nicely.

Really useful to have a pack like this if you plan on taking you quad with you on hikes or bike rides. Very convenient to have one back pack to haul around instead of several cases. But that case does look like a great pick if you are set on a transmitter case.
