DCS Ai in slew modus and sound issue

[Gulfwarfighter 3]

Hello guys,

I have bought dcs a10a and f-15.

big mistake i think at the moment.

the ai of the a10a after they attacked the targets well the plane was banked for a lefthand turn but still it go's straight ahead like it was is slew modus from fsx/p3d, not single time but every time.

i was filming it but for some reason nvidia recorder did not record it so i am going to record it later.

also why in earth is the strobe light on that plane  so bright that in daylight you can see the reflection on the sand and tarmac.

and the reflection is a ugly white triangle.

1 other thing why is the sound gone above 500kts in the outside view/flyby view not only on the a10a but every plane?

the sound only returns when i change the camera position behind the aircraft.

can anybody help me with these issue's i got?
