Will the flight model stay this way or are they working on an update ?

They are working, and has been said several times.

I know polychop Is working and that's ok, but my question Is: to date, Is the Flight model of the Gazelle still the same as at the beginning of this topic?

Is it so difficult to make a correct flight model for a helicopter?

Well i agree with the idea of the Gazelle flight model not being fluid like other helicopter models, but this statement is just bold... How many flight models have you coded for flight sims?

One day in DCS... Vipers will fly along side Tomcats... Bugs with Superbugs, Tiffy's with Tornado's, Fulcrums with Flankers and Mirage with Rafales...
The Future of DCS is a bright one

Well I could answer; how hard is it to ask pilots for advice on how a helicopter should fly?

Very hard. That is why we are in this situation as they had real pilots feedback. And now they need to rework FM.

If i use comparaison with cars and cars simulations.If I suppose most of us have already drive a car.Now how many among us are able to give a good advice for a particular model?Or simply how many can explain the difference to drive between a real GT car and a real DTM car.Surely nobody.But we are able to talk about that in a simulator.As like we do it here.
And it is useless.

Negative. The law of physics applies to both of them. You can judge from your limited car experience that there must something be wrong, when for example the DTM car doesn't slowly lose speed when you move your foot away from the accelerator (at a level road, without braking).
The same applies to fundamental behaviour of helicopters and airplanes.

Generally speaking, coding an helicopter FM is an order of magnitude more complex than a fixed wing. Imagine coding one big fix wing versus 2 or 4 (or 6 for the Ka50) rotating ones constantly changing Aoa and flexing. Add to that a propeller that pushes sideway (tail rotor). This adds some interesting consequences: vortex ring state, settling with power, loss of tail rotor effectiveness, dynamic rollover, retreating blade stall, in ground effect, effective transitional lift,... And of course a permanent unstability and 4 controls (cyclic, collective, thrust, rudder) that are intricately correlated. Things that FW pilots don't really need to worry about. Also the reason why there are so few (serious) choppers developments in flight sim. Very complex and people are a bit reluctant to spend weeks just to learn how to hover when you can be a maverick in a few days shooting missiles at migs.

Some explanations of Polychop here:
