Hi dreambox,
First off, I gave you a reputation-click because I feel that you are touching a point that is very present for a lot of our customers.
But I would also like to add our perspective to some of your points.
I think you are correct in your assessment that our patch 1.1 for XP10 took too long already. Cameron and Ben gave the reason for the latest delay (flooding of Ben´s area), but we concede the point, it has been too long. The patch is ready to go out, Ben is working hard to update gizmo so we can roll it out ASAP. No time estimate, though.
Here is my take on XP11:
When you bought the plane, it was "for XP10". No mention of "...and future XP versions" or "will be upgraded to future versions as soon as they come out" etc. So while we feel the moral obligation (and the business need) to update it to XP11, we don´t feel the need to do a rush job on it and reserve the right to take as long as we want.
We ALL have fulltime jobs. We could not allot the time for a XP11 update in due time, with some of us having other obligations that preclude serious XP-dev work for months or even years. We learned about XP11 not earlier than anyone else, and Ben warned all developers to NOT update their aircraft before XP11 was final.
XP11 is STILL not stable. In fact 11.01r1 just broke the landing lights of our plane - going from historical evidence we expect XP11 to stay "somewhat unstable" for another half a year, or more.
The 1.1 patch will bring some "ninja-fixes" for XP11 users, the worst problem being the sliding at slow speeds/in cold&dark. The remaining problems you mentioned (especially the engine problem) can be fixed with planemaker tweaks you can do yourself. The only thing that will still be off in XP11 with 1.1 will be the drag being too low and the annunciator lights being too dim.
Thank you again for the nice words about our plane (in XP10). I assure you we are working on the XP10 update and also on the XP11 compatibility patch. I may actually do my next preview video for 1.1 in XP11 just to show you how well the plane already works in it.
Cheers, Jan
