Hi,
from my experience I guess that the aileron-in-stall behavior is not correct because the adverse yaw effect also isn't realistic yet, or better said it cannot be directly influenced by parameters in the tmd file. I've spoken to the developers about the stall and adverse yaw and they would like to improve it but because of the lack of customers who would even notice that they better spend their time in other, "cooler" features for the majority of the users. To be honest the response to rudder is also not the best in a stall yet. After the stall point everything is fine, before the stall everything is almost perfect but in the stall itself... "nahh..." (don't understand me wrong here! The stall is still way better than in FSX or X-Plane, its just not quite there where Condor already is in terms of stall and entering spins)
I actually tried aileron in stall in a couple of gliders in the real life. Its not as bad as everyone sais, at least for the aircraft I flew and tested it in. Some aircraft showed reduced aileron effectiveness and of course intense adverse-yaw. I never encountered a bad wing drop to the downwards deflected aileron, which leads me to the conclusion that the drop in lift coefficient and increase in drag is not that bad at stall speed. When you increase the angle of attack another 5 degrees or so on only one wing, than you get a nice wing drop and probably a spin if not countered right away. I've not tested full up elevator and full aileron yet though, only in a side-slip with opposite rudder, which was quite stable for most aircraft.
When I want to spin I only use the rudder to get in and out of it. Ailerons in or agains spin direction had not that much effect upon entering the spin from my experience, and leaving it - depends on the aircaft. Some aircraft like ailerons into the spin, some against it to get in and out faster. But if an aircraft is able to spin than it gets there even without aileron and if it does not enter a very flat spin you should be able to get out without ailerons and only with counter rudder - elevator neutral. If the aircraft is too front heavy you probably also won't get into a stall with ailerons against or into the stall. They do the wing drop just fine, enough to bring you way of course, but they just drop right out.
Of course you should know what you are doing when trying it, have enough altitude, check airspace for traffic, read the manual, have done spins with a flight instructor before and tested it in a simulator dozens of times, etc.
Cheers,
Jan
