Downloaded the new version. Installed. Planned flight as usual.
Flight was from MMMX to SKBO.
I know there are issues in normal operations as to altitude and density altitude.
I loaded the aircraft and at the stand (gate) I was 1% over.  With burnoff from idle at the stand and taxi to rwy 23L at time of take off I was @99% of Gross of Takeoff weight.
Clearance for take off received and the problem was evident immediately.
It took half the runway to obtain 80Kts.  It took 11, 400 ft to obtain 145 kts.  V1 was suppose to be 165.  Aircraft did reach transitional lift .  At 2500 ft AGL the aircraft lost all lift and made a dive to the ground at which time a crash incurred.

My point?   What ever changes took place in version .99  its not good for thrust.  Aircraft was de-rated tremendously.

anyone else?
