You're absolutely right. I can attest to the fact that there is a fair amount of testing, but there are so many things to be checked that some of those little things (and some not so little things) get overlooked. But I don't think there's been a payware product from ANY developer released over the past two years that hasn't had glitches upon release that required some sort of patch or work around. Even this forum is full of threads seeking help with issues with various payware. That doesn't relieve Carenado, or any other developer, from the responsibility to try to put out a perfect product. That is the goal and some day it will be achieved. Short answer, no. There is a lot of work and testing done with each of Carenado's aircraft. That being said, Carenado's timeline for bringing their planes to X-Plane is an unprecedented feat. Nobody has ever attempted to bring so many aircraft to X-Plane in such a short time. It's a lot of work to get done with very short deadlines. There's bound to be things that get missed. The good thing, as you've mentioned, is that Carenado is quick to recognize the issues and resolve them. I agree, but until V10 is FINAL FINAL, there are bound to be things pop up without warning to developers. From one iteration to the next, X-Plane can break what the developers' thought was fixed. It's a little unfair to put all the blame on the developer when a lot of the issue is created by Laminar and the whole beta and release candidate process. Isn't this the eternal question we ask about X-Plane itself? I think if we take a look at just about any product in the world today, there are thousands of examples of issues the manufacturer missed that were later discovered by consumers. Automobiles, computers, cameras, baby strollers, etc, etc. I'm grateful for all the work done by all X-Plane developers. Over the past couple of years I have become more aware of the inner workings of X-Plane and the X-Plane community and I have been given some insight into all the work that goes into these products. I think we have a tendency to hold these guys to fairly high standards and when a product comes out with a wart or two we are not very kind or patient about it. Not only do we want "it" NOW, we want "it" PERFECT! As long as developers continue to provide good customer service and are responsive to the issues, I think we should be a little more forgiving of a few oversights, while encouraging them to be more diligent in their quality control.
