Hello guys,
apologies for I did not post anything recently here. We are very busy...
Nothing much to say, engine was initially tuned to curves without external stores, in level flight, on altitudes, in restrictive manner, with SAU engaged. It turned out that engine power will be insufficient in gaming environment (more subjective aircraft handling) and with weapons/stores (which are another story but must be taken into account here). This is especially noticeable with altitude, when air density fall significantly (lift properties) and engine power starts suffering (dm drops for same M). It is re-tuned; unfortunately this latest FM won't be in following DCS update (possible today or tomorrow) since the repo was locked several days ago for preparation purposes. "Intermediate" FM that will be available with mentioned update should contain number of small improvements, not noticeable for most of players, but you might notice some.
When it comes to high-altitude/high-speed aircraft handling, things are "touchy" - patience is the word. There is no playing superman at high altitude; there is no air there guys, and 21 wings are small. To achieve highest altitudes you need to accelerate in level to at least 1.8M then climb. You will be around M limit as your IAS drops. For cruising at 15+ -17km with externals you need to get to 10km with reasonable amount of fuel first. Otherwise, the game will be short.
Best regards.
