Cobra maneuver at 1992 Farnborough, MiG-29M 9.15 with Valery Menitsky, the chief test pilot of the MiG-29M 9.15 program:

The one and only romanian air force 9.13. This red 53 was a former Moldovan AF bort number 01:

It is a sound bug of the video recorder in the game, so it is a sound bug of the DCS. Especially, a quite new bug, since this record avi option has no issue until the last update. -> This is my real problem, because I have no other option to make videos with a useable/right fps quality. Maybe the png+audio option would be the right way. Somehow I will dubbing the separate audio with the video sequence in an editor.

If it is a real-time screen recorder, then is not a solution for me, since the in-game FPS is less than 20 at low, and around 15 at partial-medium setup. I would not like to recording a 15fps video. Until the last DCS World update, the record avi was fine.

No additional software I used. This is just the straighforward result of the Record AVI menu from the mission editor. I set everything, tried everything, either the Uncompressed AVI (25 sec, 60fps 1920x1080 is average 9GB) or the comporessed ogg+vorbis .ogv option. The result is the same, while the source file track has the right sound (external world sound, engine noises, etc, but no cockpit sound -> as I set it up) the rendered video (made by the DCS Record AVI) has just this weird sound result. If you save my tracks and try to render it by the record avi, you will see, if it is a local issue, or a general in-game one.

I discovered a sound bug. When I make a track file with the proper sound setup (no cockpit sound in external view), the playback shows the right sound, but the video recorder is recording only a weird portion of the sound channels, such as one internal cockpit voice and some additional external sound effects. And this is completly different than what the saved track file has. The result is actually quite far from the useful. In this video, I had some extrenal world sound, but just partially: And here (one update before) everything was right, except the internal cockpit voice in external view.

The 9.15 MiG-29M was planned to replaces all the former Su-17M4 and MiG-27M regiments step by step in the mid-90's. The first group of pilots was chosen and sent to Lipetsk for the transition, the transition platform was a squadron of 9.13 MiG-29, painted with the greenland camo. All of those 9.13s were new one, because of that, at that time, all single seater East Germany NVA MiG-29 9.12A and all czechoslovak AF MiG-29 9.12A was painted to that camo. It was in around 1989-90. However, no any 9.15 built in serial production, because in 1991, the Sovietunion collapsed. However, the first public appearance of the 9.15 was in the West, 1992 Farnborough, later in this year in Moscow, Mosaeroshow, Zhukovsky and even in the Le Bourget 1993. But in december 1993, when the new goevrment re-calculated the military budget, all MiG project (MiG-29M, MiG-29K, MiG-31M, Buran shuttle) was cancelled, mostly by the underminding work of Mihail Simonov, who was the committe member and the chief designer of the OKB Sukhoi in the same time. Unfortunatelly, all of the airplanes above, the MiG-29M for the air force and the export market, the MiG-29K for the Kuznetsov true capabilites, and the MiG-31M for the PVO would be a great success.

The P&W F100 series engines have the pneumatic nozzle actuator, that's why that distinctive nozzle sound. The GE F110 series, the F404, F414, The french engines, or the soviet-russian designs have hydraulic nozzle actuators, so their operation noise is way quieter. So as the P&W F119 or F135. That unique nozzle sound is only the F100 family's speciality. This is the Convergent Exhaust Nozzle Control (CENC), which drives the nozzle through bleed-air from the 13th compressor stage.

Ok, agreed.

First of all, let's see this Japanese F-15s at dynamic high AoA maneuvering: Back to the "nice airshow BTW" footages, the sustained low speed - high AoA flyby by the F-15E was at 32 degrees, not 25. Based on this article about the KEEP EAGLE program, the F-15E has exactly same AoA limitiations, as the F-15A-D fleet has, but with a better handling characteristic. More capable spin preventation and departure control, than the normal Eagle had formerly. https://books.google.hu/books?id=F9hnha2ESfMC&pg=RA5-PA16&lpg=RA5-PA16&dq=f-15e+strike+eagle+high+angle+of+attack&source=bl&ots=yHVVUw__wK&sig=ACfU3U0eMw1k5ElDYoIX2oDd84CVK9LV7g&hl=hu&sa=X&ved=2ahUKEwj_qpP3gdH5AhU3YPEDHTCjDos4PBDoAXoECAMQAw#v=onepage&q=f-15e strike eagle high angle of attack&f=false Page 183: " KEEP EAGLE found that the F- 15E now exhibits " excel lent flying qualities above 30 AOA ...better than the F-15A/ B / C/D at high AOA.” In fact, during KEEP EAGLE testing, not a single unintentional depar ture / spin was encountered at high AOA . The bottom line for Strike Eagle drivers is that the F-15E is more departure / spin resistant than the F - 15A- D at high AOA. Also, if departure / spin occurs, the Strike Eagle will exhibit good spin recovery characteristics in both air- to - air and air-to-ground configurations — even when asymmetrically configured with asymmetries in excess of 8,000 foot-pounds. The F- 15E still shares some low angle of attack departure characteristics with the F-15A-D family." "Unlike the F - 15A - D , the F - 15E does NOT experience ... a region of reduced directional stability around 37-44 CPU " "Hopefully, you've gained some insight into the handling characteristics unique to the F-15E. While the Strike Eagle exhibits some better handling qualities at high AOA than the F- 15A-D, it still shares some of the low AOA departure characteristics with the rest of the Eagle family."

Yes, but actually no. There is no significant AoA losses. (On this video, there is no CFT at all by the way )
