P-Thrust,X0-min Drag,Xi-Inductive resistance
The turn equation
If Nx = 0, that is, the thrust is equal to the resistance, then acceleration does not occur. According to the schedule, there is still just a huge margin for acceleration. Ie, the plane, as I thought, lacks 1.5 tons of thrust

At 500 km/h and 5G acceleration it loses speed. Unable to support sustained turns per the chart;
(I cut the video wrong, but skip to about 1/3 the way through and I stabilize the turn in my testing)
That’s because it can’t sustain 82 degrees bank angle whiteout either losing speed or altitude at 200kt (the speed I did the test at)…
In my test I was sustaining 71 degrees bank angle (which matches for a 2.95 horizontal overload->3G load factor)
bank angles = arctan(centripetal overload / vertical overload). Vertical overload is always 1 in a sustained turn
Ny we see in game is bugged (that’s something I forgot to share on the forum)… when I did my test with the MiG-29 Ny (normal G load factor) indicated a result that was basically equal to what was de facto the horizontal overload (the centripetal acceleration), while it should have showed an higher value.
Although if the error it displayed doesn’t increase with the G load, that shouldn’t matter much at 5g
when Ny = 5 you are approximately doing 5.1 if the same Ny to true G load delta is the same that it was at around 3G
Towards the end an Ny of 3.9-4 would result in speed loss at 500 km/h…
3.88 Ny stabilized at 470 km/h ish… when 3.88G should result in speeds of approximately 1450 km/h before it “stabilizes”.

The problem still remains. The plane is not able to accelerate, although in reality it should

Chart implies that from 400 km/h + at 3G it should accelerate, but 3.88G at 470km/h it is stabilized…
Should not stop accelerating at 3.88G until ~1450 km/h based on the chart.
Clearly it is missing a lot of energy.

I would say a very lot
At an instrument speed of 950 km/h
Performing a U-turn at full afterburner with an overload of 6G, the aircraft adds 20 km/ h in 1 second
Altitude and weight for test?
2000m 13000 kg

According to this schedule, the aircraft is able to climb vertically up to a height of 1 km
At the same time accelerating
During this test I was able to accelerate to 970 km/h in 1.11 seconds in a 6G turn at 2000m. This seems accurate, but at lower speeds it does not. Likely has correct optimal speed thrust but incorrect static thrust.
Let’s slow down, let’s say 700km/h
700 km/h and 6G U- Turn?
yes, according to the schedule, you should continue overclocking, but slower
It is practically at a standstill, unable to accelerate beyond 700 km/h at 6G. In fact, I think it decelerates unless I am slightly losing altitude.
let’s slightly raise the speed to 800 km/h
MiG-29 versus Mirage 2000: personal account from Air Marshal Harish Masand
In a turn towards the Mirage, I found we were crossing even 90 degrees before the Mirage. Also, I had noticed, while practicing for the displays, that the 29 accelerated even at 9g at low-levels if the power was ahead of the onset of g and, therefore, required a coordinated turn with power management to stay at the optimum speed and at the desired g.
