Update 18/05/19
I had a conversation with the developer. Here was what I can print:
"We are working on the home user 206 right now.
Yes, we had a bit of detour getting a different, new helicopter ready for CAA approval working with a large flying school.
The last of the 2d gauge should be finished this week but there is still work to be done on the 3d model. These are things like the magnetic compass that don’t have any significant Dodosim specific coding in them.
We have had to make some coding changes because changes in Prepar3d V4.4/V4.5 broke some of the dynamics coding that we wrote and tested for V4 and had worked fine up to V4.3.
So that caused us some extra work but better than it happening after release.
We are making some changes to the company so that we can keep up with support, admin and get the web site up to date etc without losing time on the creative side as we have in the past.
All the best"
