BF109's Always Seem To Keep Their Energy?

[Acumen]

After playing on and off over the years (I have been here since the beginning!) I have re-immersed myself into the sim with my VR setup. I have noticed that the BF109 lineup seem to to never lose energy. They turn, climb, roll, etc. with nary an effect on their energy. Is my perception off? Are they overmodeled? Or is this truly the case?

The first one was correct.

The Germans invented EPO already in 1941 ...

The 109 is a small light plane with a powerful engine coupled with an efficient propeller leading to it having a high power/thrust to weight/drag ratios. Having these qualities leads to having great acceleration, climb and sustained turn capabilities. The series is pretty good at retaining speed at the usual dogfight speeds and getting that speed back to that level but a weakness is its high speed energy retention isn't that good compared to other fighters like the p51.

I believe that you are correct, but this behavior is not specific to the 109 (although I think it is more pronounced since they have slats and many planes do not). 

 

The game engine being used was developed for WWI aircraft (FC) and while it does a good job simulating how those aircraft behave, heavier and more powerful WWII aircraft feel too responsive. In my opinion the flight model is on rails, stalls are gentle and too quick to recover, the effects of prop torque, p-factor, and gyroscopic precession are too mild, controls do not get mushy at low speed, energy is recovered too quickly/not bled enough with violent maneuvers. Because of these issues, one can (in many circumstances) ignore BFM/ACM principles, defy the laws of physics, point their nose in the direction of their opponent, and get a guns solution.

 

But then again, this is just my opinion. I am sure there are those more knowledgeable than I am that can weigh in and explain it better.

Did you observe this with AI or humans? AI FMs are quite different that what we have. Best example: load a few Spit9 and P-51 in the QMB and check their tendency to fly inverted for really long periods of time.

Real Spit and Mustang fly even more on rails in real life than I perceive it in the game. The aircraft are very aerobatic and very responsive. 

 

Control authority near and toward stall is a different matter though and it is where every sim is in delicate territory.

That's not true. The AI uses the same FM as human players.
