..K11W2 was opening to a blue screen.
I had to replace Head5_D0.msh 12/12/2022 by Head5_D0.msh 11/7/2022 from K11W1(multi).
..NOWWORKING.
update 23/02/2023:
..about your query:
My Q3W1_25th_Jan's autopilot took off at 120km/h empty+ 100% fuel; then at 112km/h with two 60kg bombs added;
..at 114km/h with two 100kg bombs added.
Ai next flight did well also, empty. Ai with 2x60kg bombs took off, but did not gain altitude; moments later went downward, wheel-bounced then crash-bounced-exploded onto a very low hillside little land-rise.
Airfield at Hengyang, local altitude indicates 93m. U tried some other airfield?
