The top plate protects the electronics and serves as a battery mounting place.
The bottom plate protects the PDB in hard landing scenarios. The round tube is in place to avoid object etc to enter the body of the tricopter. It allows to see leds and to have separate screws for the protection and the PDB assembly.
A battery alarm has been added. 3M (r) dual lock has been used to make it solid to the tricopter body
Previous led solution was not making the rc model visible enough and too many leds were noit doing their job. This is just one instead, with a couple of resistors to lower the voltage to power the blue light. This is just a reference point and a display of the power being connected, LiPo on.
Legs now are all of the same length, so that when the flight control board starts and sets the levelling, it is properly horizontal.
