Unsolved MIG-25 impossible to take off
-
Just setup a TE and try to takeoff with the MiG-25.
It is impossible to perform a takeoff if a player controls the plane.
At 240 kts pull the stick as hard as you can do and the plane simply does not react.
When you sit in the pit in the air the plane in flyable. -
@molnibalage I never tried this, but has the MIG-25 flaps simulated? Maybe it’s in the upper position on take off.

It does not matter at 240 kts speed no matter the flap settings you shall be able to take off.
I tried a trick, I tried to make a roll while I pulled the stick. The plane was able to lift off with this trick but the performance was not the same compared to the cases when I started to fly airborne. -
@molnibalage I have made a simple TE and I was able to take off under 200Kts. Youtube quality is shit, but on the bottom of the screen you can see the speed. The flaps was down default.

@molnibalage this has been a physics bug for all non-AFM planes, known for over a year

workaround is to fast-forward time in 2d, then enter the jet already airborn

And I have never been able to reproduce this bug.
As you can see on the post above the mig25 takes off fine
This one is really a PITA

I have noticed this bug since 4.34 or 4.33. Based on the trials I made during Eurofighter FM development, before progressing with an AFM, I could alleviate the problem a bit working on the low speed CL values for the takeoff relevant AoA region and disabling slats on ground. The loadout certainly plays a role. Clean it was possible to takeoff, add a few stores and it sometimes becomes impossible to takeoff. I made some cross verification trials in older mods, like Free Falcon, where these issues are not present with the same flight model. Wasn’t it said that the FM code doesn’t like aircraft with a certain pitch angle while on ground?

Maybe it the specific airstrip is the issue. To me the plane behaves strangely, funny pitch rates during roll is experienced. I tried landing (I sit in the pit following takeoff) then takeoff again. It was not able take off.
(I discovered the takeoff issue when I checked the performance of the MiG-25 compared to reality. In average it was surprisingly accurate. In some areas the drag is underestimated in other cases over as I can judge. But when I performed the maximum performance interception by the book. The flight time to 400 km range the real life vs BMS flight time was almost the same. In 13 min 10 sec nominally by the book up to 21 km to 400 km horizontal distance. In BMS from 200 kts 200 ft to the point was 12:40 + but the time of the takeoff shall be added = almost identical.)
