When these units were first announced, I pre-ordered two units with a $200 deposit. Subsequent announcements indicated they are just waiting for the FAA approval process to be complete. I saw that Aircraft Spruce is advertising that the experimental units will ship on 12/31. I looked at the certified page and saw they are listing a 1/16 shipping date. I just wondered if anyone has heard an update on the certified unit shipping date other than this info on the Aircraft Spruce website?
