DCS MiG-29A Flight performance and air drag seems weird

[HoMeBoY]

Premise, I fly almost all DCS modules and I have 5+ years in the sim to what I consider a professional level. I am also a student pilot.

I understand the flight model is the same as FC and it was considered more than good and realistic already, but right now the MiG-29A behaves completely different from any other module. For example:
- it's very difficult to bleed air speed, even when idle and pitching up. And it seems it never really stalls and not even buffet. I could fly at around 120kts easily but it seems a very low speed to me
- because of the difficulty of bleeding air speed, landings are weird and generally flat and it float forever
- you can flare on land and then keep the nose up almost forever
- you can sustain AB climb, sometimes supersonic, way past 35,000ft
- the jet overall seems faster and agile of anything else out ther in DCS. 

I don't know how a MiG29 is in real life and to be honest I would expect this kind of performance from a modern military jet, but then all the others modules like F/A-18 and F-16 must be wrong then as they have less performance than the MiG29.

In general I find F-16, F-14 and F-4 (in general Heatblur modules) to be the best transmitting realistic reactions and performances when it comes to modern jets....so TLDR, this MiG29A left me perplexed as it feels very arcade to me

Hi, 

please include a track replay on Caucasus showing the issue and we can review it. 

If you have any public evidence to support your claims please dm me, but comparing to other modules isnt probably a good idea, each aircraft has its quirks and characteristics. 

thank you  

[HoMeBoY]

Hi thanks for the reply. Tonight I will record a client track from the Caucasus Free Flight and Landing from Final Approach instant missions and leave some comments about my experience.

I am not "claiming anything", it was rather to get other opinions from the community. Even if I don't compare modules, it will feel overpowered in terms of pure flying performances when joining an MP server with diverse adversaries.

Lastly, I understand it just came out in EA and I am just hoping it will reach the same level of polish as other modules. Something that the MiG29 is already doing better than the Phantom for example are the water drops effect on the canopy.

[BIGNEWY]

No worries, we are happy to look at the track and investigate.

The high lift and thrust seem consistent with what the Fulcrum is known for (I don't have any data, just from hearsay)....
However, I would agree, that it seems almost impossible (in comparison) to bleed speed.

Very similar to F16, which is not surprising in my opinion.

Bleeding speed in the Viper is a piece of cake. Especially when dirty. Try a back to back comparison with the Fulcrum.

From my (very subjective) pov, the Viper feels "right", whereas the Fulcrum feels like it was covered in butter. Very slippery.

If I recal correctly, isn't MIG-29A a pretty small and light aircraft (like the F-16) but in comparision with the F-16 it has two engines, perhaps it explains the high thrust to weight ratio.

The MIG-29 has a pretty wide fuselage blended with large wings, perhaps that explains the high lift?

[primus_TR]

Well, the 29a can reach Mach 2.3 for a reason.

True, but with gear and flaps down, it should still bleed speed like crazy (in idle).

Yes I exactly. If you compare the F-14 and MIG-29, they have both two engines, but the MIG is much smaller (and has less weight) that could explain it.

MIG-29A must be the smallest aircraft in DCS with two engines mounted?

True

If I understand you well, you have 2 main points:

- the jet doesn't degrade speed like you expect ; in this area I would say we are probably poorly equipped to judge as it is not very comparable in terms of aerodynamic design to the US jets you mention. For example the wing area of the Mig-29 is 38m², compared to 28m² on the F-16. My understanding is that the flight model is done based on publicly available data, which is plentiful considering the age of the jet. But I could be wrong here.

- the jet's performance is "too fast". The fastest jet in DCS so far was the F-16C (in a drag race) with a thrust-to-weight ratio of 1.08 considering a clean jet with full internal fuel. The MiG-29A has 1.12 in the same configuration. Based on videos like GR's drag race test, the MiG-29 actually performs as one of the best, but not the best fighter in pure performance. The fact that it performs well at high altitude is probably due to its relatively larger wing area compared to its weight (it has a very similar empty weight to the F/A-18, similar wing area as well, but 0,5t higher thrust in full afterburner).

All data comes from Wikipedia.

It would be more efficient to base expectations for a DCS MiG on a docs for a real MiG. MiG-29 and F/A-18 or F-16 are different aircraft with different performances, you can't say "It's a bugged model because it climbs faster than F-16", better say "It's a bugged model because it climbs faster than a real MiG-29 here's the graph's superposition of real and model". Now that would be "professional level".

The aero manual says the controls have good authority even below 200 kmh. 
 

The engines do have a high thrust in idle 

It should sustain AB climb at peak climb speed (Mach 0.9-0.95) up to 50,000 feet, and still climb higher as long as speed is higher 

It should buffet around 15 degrees, you can feel it with FFB. 
 

I think you will find that DCS F-18 still out turns it in every way.

Any thoughts on the apparent "lack" of drag when dirty, or do you think it's a function of the high idle thrust?
