Sub Panel Mounts

Over the last couple of days I’ve been slowly refining the design and construction for the sub panel mounts on the pilot side. The two biggest boxes going in this area are the Vertical Power and Transponder unit. Originally I was planning to orient these horizontally, but when I installed the bank of switches, there isn’t enough room. So I switched the orientation to vertical. This also meant the standby battery wouldn’t fit, so that is going to move somewhere else. Tonight I finished the construction and test fit everything.
