this is an early revision of this frame. inprovements have already been made on the armattanproductions page.

dual camera mount is perfect for me. it also has a beefy bottom plate for ruggedness. a low stack height so the top mount battery sits close to the prop line. There is lots of space for the build with the option of two 20x20mm stacks or one 30x30mm
I had a spare 30x30 AIO fc and I also used the Foxeer Mix in its out of box 30x30mm form. Will swap out the lens to a gopro lens to avoid as much fisheye as possible.
Interested in how these cheap Tyro motors perform as well as the Mix.

--update 1st April 2019
tyro79 motors are surprisingly smooth. efficient due to the lower KV. the foxeer mix is terribly fisheyed. what is worse though is the oversharpening and low bitrate.
the cam plates have a bit of wobble and it shows up in the HD footage. this is a protoype frame so this already has been fixed in the latest revision.
i was pleasantly surprised how well my shorter 1300mah 4s packs sit in the top plate. I'll easily get 5 minutes of flight but hasnt been proven yet because of dogs :)
