The Mooney has been in development for a number of years, yes. Dynon has limited engineering resources, but the main hold-up is the FAA. Also, the Mooney came after the A36 Bonanza, then the Cessna 182, then a couple of updates to both of those (partially because of an engineering oversight), then the Baron is next and the Mooney after that. In the middle of this process, which had been taking about a year to get the FAA office to approve it, they starting using another FAA office that is faster at the processing, and they are waiting on the Baron approval. The Baron has been delayed because of 3-5 changes they had to make to earlier models. I would expect the Mooney approval Q3-4 of this year. I am not speaking for Dynon, and this is in no way an official statement. Just my own understanding of the status. In the past they have given time estimates, but when delays come, everybody gets upset because they couldn't meet the deadline due to no fault of their own. It's dealing with government that has little to no requirement for measurable productivity that causes most of the delays.
