Hi
when I installed block B first, I had great a flight attitude on manual steering. After installing Block B, Block F, ACE and Sound (in this sequence)  there was this problem with the centertank and absolute unflyable behaviour of the plane (each time stalling and  uncontrollable tumbling/turning etc.) Now I installed again without ACE and: its going fine again.
Should I try with the new V2.0 version of ACE again?? I will wait for SP1 Block F maybe.
This planes has a lot of potential.

BTW in instrumented flight after reaching cruise altitude I had overspeeds several times now!! BUG? or ma mistake somewhere?
