Nice job. I bought a metal case with the foam already cut, but it creates a problem if you want to swap out landing gears, I found that one out the hard way! I probably could have cut some foam, but I hated to mess with it. it does have a lot of extra compartments; I just hope it is enough for FPV equipment. If not, I may go your route!
And, welcome to the forum! If I've already welcomed you, I just wanted to do it again!
