A2A products for me are controversial :
I do like the visual aspect but I think that if Accusim would be part
of real world aircraft and A2A would have been a real world aircraft
manufacturer, personally I wouldn't have flown ANY of its planes.
I' ve logged more than 50 hours in real 172 SP without any problem.
Conversely I've found the engine operation of A2A 172 SP accusimmed problematic and too much delicate.
The well known 172 floating ground effect before the landing flare
is simply funny : It should be reduced by at least the 40%.
A2A WOP3 P51D Accusimmed : if it is installed I've further problems with the 172 (sound and FDE) so I can't have both planes
installed at the same time, furthermore the Mustang struggles to
climb like an heavy chicken-always-on-the-edge-of-stall.
I've done everything in the right order following A2A suggestions about accusim upgrades and so on but nothing .
On my brand new PC there's only the 172 installed and now I'm afraid to install also P40&P47... Just my experience, and when I start to have too much troubles with payware expensive products
I can't say : I do like this developer...
Your remarks about the C172 are certainly valid, however there was definitely something wrong with your Mustang.
I have all of the Accusim warbirds and the Mustang climbs very easilly, it is quite light and powerful. The only Accusim warbird that has problems to climb is the P-47, when I load it with full fuel and biggest external fuel tanks.
Concerning the "conflicts" between the C-172 and the Mustang however, this is not the first time I see that. A friend of mine had the same problem with the C-172 and the Spitfire. He has not been able to get the Spitfire to work properly. The Accusim update would always mess it up completely, to the point that the maintenance hangar would never open (it kept showing the red label, like when you didn't set your parking brakes). A2A has not fixed the issues I think, so that might explain the problems of your Mustang, perhaps ?
That being said, I fully agree about the remark made earlier in this thread, about "there's A2A, and there's everything else far second".
Yes, Milviz and a few others make great models and excellent systems. But let's not compare a warbird with a modern jet. Let's compare warbirds with warbirds. Accusim warbirds are alive, simple as this. When I switch to other warbirds from other companies, no matter how good they look, they don't provide this "alive" feeling that Accusim does. And this begins right when you start the engine.
Now, concerning that pseudo "development non-update", I made a remark about this on the A2A forums already. Of course I understand they want to be careful and not promise anything they can't deliver anymore (F-104, F-4, T-33 anyone ?

). But what was the point of such an update really ? I would have prefered them to wait a little bit more and at least be able to tell what they were working on.
