I for one appreciate Dean giving his thoughts. I think the DC Concorde is a great addition!
Study level no, but lots of fun aircraft aren't. I'm a real World Jet and Helo pilot, but not Concorde! Although, I did fly on her as a passenger. I like how the cabin was modeled with the inflight mach and altitude displays -- brought back some memories!
The autopilot seems really difficult to manage at first, I'm going to look more into that, but I'm using less than full fuel loads (with Airhauler) and there might be a CG issue, although it shows within limits.
When I say difficult, I mean wild excursions and difficulty capturing altitudes.
Look forward to future updates, and good luck with your business!
