Sorry for the late reply.
Merry Christmas/Happy Holidays to you too, sir.
Not much has changed except for progress. It's one of those things where the non visible parts are progressing. We were also hoping it would be ready before Christmas, but unfortunately, it was not to be. libturbine is also progressing, but it's also taking time. Saso is a person who believes in doing a thorough and professional job, with as few bugs as possible. He really pushes himself to make sure we all get what is expected.
We don't think it will be too much longer, because we want to wrap up the TBM, CL650 and start on the next project.
