Finished up the plumbing the pitot tube by drilling the holes in the gear tower and at the wing root and putting in the grommets. I then ran the tubing and cut it to length. Tried a couple more tricks on my AFS to get the CDI to come up - no luck. I have asked on the AFS forum but so far no replies. I also started trouble shooting the lack of mic in the back seat. I think I might have left off a wire when I was wiring the aft stick PTT -- I'll investigate that tomorrow.
