Reaver H140 Micro FPV Quadcopter

This is my own designed micro quad, All electronics are contained inside the shell, that makes for a very challenging build. The ESCs are sandwiched between the arms.
To be used with 3 inches props and 1306 motors, 4000kv preferably though I am using 3100kv at the time.
My configuration
-Afromini32
-DYS SN16A esc
-RCX 1306 3100kv
-Eachine LT200 vtx
-micro minimOSD
-micro 600tvl 170degrees camera
-Frsky D4rII without pin

I don't recommend printing in PLA as it will be quite heavy and
