I truly don't understand the countless of complaints about PMDG. I've been a PMDG customer for more than 10 years now, and I was always astounded by the detail this team has put into their products, especially when you look at the limitations that FS2004/FSX came with. They always put the simulation to a higher level, and they managed to do the same now with X-Plane.
Most of the complaints even seem to be on such a high level that it's sometimes even unbelievable that they come from people that are a) neither a ) pilot or b ) never even flown that aircraft. In the case of the DC-6 the combination of both a ) and b ) seems to lead to assumptions that sometimes don't even have any backing.
In fact, the DC-6 was just released. When is a product ever perfect on release? Do people really expect no flaws on a new product? Heck, even real aircraft manufacturers have trouble with their new airplanes. I believe and always believed that PMDG takes feedback serious, and with the update they just released they also clearly show that they care about their customers. They don't need to comment to EVERY critics, as long as they still evaluate them to find possible problems and fix them.
At last I also want to mention that a lot of people these days simply have exaggerated expectations. X-Plane is NOT the perfect simulator, and virtual airplanes will not fly 100% as they do in real life, they don't even do so in 30 million dollar simulators.
Just relax and let PMDG do their job, and in my eyes they do a damn good job.
