Incorrect thrust to weight ratio for F/A-181 Black Wasp II.
F18C TWR: 1.09
F22A TWR: 1.18
The Black Wasp II is supposed to be a fifth generation fighter with a blend of the F22 and F18 performance levels. It is ridiculous to have a TWR of less than one. Seeing as the engines of the Black Wasp more closely resembles the F119 engine found in the F22 one would expect similar performance in the Black Wasp II.
Not as good an example but I tried to create a real world scenario.
Black Wasp is unable to maintain airspeed in steep turn with attitude of less than 10 degrees with max thrust.
Incorrect Top Speed
Incorrect top speed of F/A-181 Black Wasp II. Again, one would expect the engines of the Black Wasp II to more closely resemble the performance characteristics of the F119 engine found in the F22.
Top Speed: 1915 km/h
Cruise Speed: 1250 km/h
Top Speed: 2410 km/h
Cruise Speed: 1963km/h
F/A-181 Black Wasp II (video)
Top Speed: 1320 km/h
Cruise Speed: N/A
EDIT - Thank you to Phoenix Two Zero
The amount of speed lost during any turning maneuver gradually decreases as the jet gets slower, due to the difference in maximum thrust available vs airspeed, (if the difference in airspeed in the output of the engine is much greater than the airspeed of the aircraft it recovers much quicker) fighter jets reach a point during a hard turn where the available thrust is enough to overcome the drag created by the jet during the turn (the value of which also drops with decreasing airspeed) and it reaches an equilibrium point where the jet doesn't accelerate or decelerate if the turn at full throttle is maintained (usually this is a really slow speed that's inefficient for rapid turning, but enough to keep flying)
