On the camera, there's a part of the FC manual that mentions OSD input (Page 10 towards the bottom) that I was hoping would just tie right into the camera, but if not I guess I'll have to pass on those options until I can get my hands on one of those controllers. As for the fitment/size, I had no idea there were smaller cameras being used now, but I hope it fits; I got the Avenger 215 5inch since I couldn't find a Martian 2 that would deliver before I have to go out of town for work for a while.

That's good to know that 4-in-1's are getting better though. I did like the idea of them until that guide said they were unreliable. When I start making upgrades or move on to a new build, I'll have to try one out.

And no worries, I realized I screwed up - at least in part - as soon as I saw what I had ordered, thanks for the guidance!
