Hello Georg, I am afraid that the changes to the behaviour of the A-10 and it's autopilot are my fault. I had to re-appraise the A-10 YASim config after a bug concerning the wing incidence in the solver was fixed. After the bug was fixed the A-10 config still seemed to solve with reasonable numbers but I had also found out some more information about the A-10 'loiter' mode, where one engine is shut down to save fuel, and wanted to aim towards making this regime work, as well as the normal regimes. This meant changing some of the values I used in the YASim config, which in turn has changed the flight characteristics. This is not to mention the change in the wing incidence, which just in itself makes the 'new' version very much a 0.1 release. For info, from looking at a lot of pictures and drawings, the A-10 appears to have slightly negative wing incidence and flies 'nose-up' most of the time. This would fit with the apparent depressed angle of the cannon (which in the current FG version incorrectly fires straight ahead). The work that Alexis is doing on the cockpit will actually help refine some of the numbers used in the YASim config. For example, when we think that the viewpoint from the cockpit is correct we must also be able to see not only targets that we may be firing upon but also the runway on approach, which in turn narrows down things like the AoA in that regime of flight and which can get fed back in to the YASim config. The autopilot structure/hierarchy has almost been completely re-designed, is very experimental and the A-10 is the first aircraft to use it :) (The Canberra will be the second, when Josh gets the updates sorted out ;) and the third will be the SU-37 I've just started modelling) I wasn't sure what you actually meant by sensible in the 'nick' axis. Anyway, cutting to the chase, what are the characteristics that you don't like or think are wrong in the current version? I guess I should mention that I haven't been able to get my joystick working since moving to alsa (j/s port on soundcard) so I can only fly using the mouse or k/b atm, which isn't very representative. Both the YASim config and the autopilot certainly need more work. Just a last thought - are you using the cvs version of FG?
