Thanks all for the very favorable comments.
Geek - too early to give a review on the antenna. Lots of calls come in clear and strong; especially ATC. Sometimes other aircraft not so much. Question is: is it my antenna/radio or theirs or other radios/interference? More flights should give me the opportunity to come up with a better answer.
Phil - you are correct; it was two years and two months plus a few days thrown in just to be sure. The funny thing was, on day one I posted on the white board in the shop: "Question - when will it be done. Answer - Tuesday." Turns out it was done on Tuesday.
The number one electronic issue to address is the ADS-b. I'm pretty sure that was solved this afternoon - the next flight will be the test.
