Question for the 1C/777 Dev Team, regarding pitch behavior

[Guest deleted@50488]

At another thread, about what has been called "wobbling" or "rubber-band" effect in pitch ( and also in yaw ) of practically ALL aircraft models in IL-2 BoS, someone has posted a link to a video showing the effects of flap deployment in pitch attitude.

 

Since this is not exactly what has been discussed regarding the wobbling effect, I would like to formulate here the question, and if possible ask for footage recorded by the Yak-52 pilot showing the effects, IRL.

 

Of course we all know a Yak-52 is not representative of the whole set of aircraft modeled in BoS, but still, it would be great to see how it works in that aircraft... so... here it goes:

 

1) After achieving trimmed, level flight, in your test flight, please perturb pitch by pulling the stick, deflecting it until the pitch increases by at least around 10º, and then let go of the stick, preferably showing that return to neutral in the film. The return should be prompt, not arrested by pilot control to impose a soft return to neutral - leave the stick ( hand's off from it ) from the deflected position.

 

2) Check the rate at which the aircraft nose drops to initiate a series of oscillations ( phugoid ).  We believe the initial return to the trimmed AoA should be soft, or at least not as abrupt as it is initially in BoS...

 

3) Please repeat for a pitch down input.

 

If such footage could be recorded, that would be great :-)

 

Yaw is also affected by this wobbling, but for a start, it would be great to check what's happening with pitch...

 

This being said, I believe all aircraft show positive pitch stability in IL-2 BoS, although they can respond at different paces ( their phugoids having different shapes ... which is perfectly acceptable ).

Yea it would be nice test to do.  I belive that actually DCS is much closer to RL regarding pitch stability oscilation.  BOS planes expecially German planes are affected by spring effect in pitch axis.

There is a problem with such test. Every aircraft type may respond in its very unique way. It would be foolish to believe a test of an Yak 52 represents the behavior of WW2 fighters we are concerned about. It may be close or not. Of course the more real aircraft types are tested the better but is it financially possible for the developers team to conduct such research? Also the flaps test only represents the Yak 52 tested and may have very limited relation to the real world 1942 Yak 1 we are trying to fix. And it's nearly impossible to relate the test to the Bf 109 types.
