so what should be changed?

i think nothing, 96 cm’s seems correct, DCS is just a unrealistic game

Turnrate report has been passed to the developers, Community Bug Reporting System, now we wait and see

Only about .5/.6g? And how was it on the dev server?

about the same at lower speeds but at higher speeds it was as high as 1.5g off in the dev

What about oswald efficiency? did you find any information about this? i sent you some things that i managed to find related to su27 not sure if you saw that

oswalds efficiency and other random IRL specific values dont really matter, the OE can still be incorrect but the flight model behaves correctly. Gaijan has their own way of making flight models and you cant base bug reports off datamined values. Reporting turnrate as incorrect from manuals is enough to fix the flight model just fine.

0.5G is a lot

These people who have experience reporting know a lot more than we do, let’s just see what gaijin does.

Hopefully, Su-27 will become better with some changes. İt is already better than the abomination SMT

0.5G especially at low speeds is much more degrees per second compared to 0.5G at high speeds so I think it will make a difference in slow speeds, if it only could hold some speed tho…

Hopefully, with better engines and stuff , this problem will be solved when Su-35 is added next December lol

alright then, but still doesnt look right the amount of speed that the su27 is bleeding…that book that even was signed by the su27 designer could be a good source, but i trust you, i hope the su27 get fixed thanks for the bug reports

yeah true, lets wait for them to fix the su27

Developer answer:

User used configuration with 4xr73, with 11min of fuel it is ~19200kg, +400 heavier than reference 305kg/m2 wing load.
18920kg with 4xR73 should be ~9min of fuel.
18920kg with 2xR73+2xR27 should be ~7.7…8min of fuel.
Sustained turn rate for ref weight is correct (and even overperforming a bit).

22800kg weight is given for 2xR27+2xR73 configuration. Not other weights.
50% fuel is 2600kg (base fuel load 5200kg), so the actual weight for 2xR27+2xR73 (720kg according Su-27SK manual) with 50% fuel load should be 20200, 1280kg heavier than used reference 18920kg weight. It means article used clean configuration, or less than 50% fuel actually, or used more than base fuel load for 22800kg weight, or it has mistakes or misprints.

However this changes nothing, because it was clearly set that comparison was calculated and estimated for the 305kg/m2 wing load (18920kg).

TLDR according to this graph the Su-27S is correctly configured I wouldnt expect the flight model to change

The FM is shit and accurate or is shit and innacurate?
