Plans: 1. Install the transponder. Status: Started. I picked up the Trig transponder/ADS-B bundle from Spruce today. The unit was much smaller and lighter than I imagined. Three grand, $$$, but necessary to fly most anywhere in Orange County airspace. The proximity to LAX and SNA not to mention the new ADS-B rules pretty much demands a full equipment suite. I started with the easy part. The mechanical installation of the main parts. So far that is the control head and GPS antenna. As I had made provision for this equipment there were no significant issues to resolve. The most difficult part will be the construction of a wire harness to interconnect everything.
