DCS F-15 Vertical Acceleration

Various shots of the DCS F-15C accelerating vertically. I had success starting my rotation from 130-300 KTAS up to 12,000 ft and up to 4,000 lbs of fuel. I'm not sure whats optimal but this seems to be a good starting point for this and most other aircraft as well. I'm curious to know what others have done. Wx for this recording was QNH 28.XX. If you try this at QNH 31.XX performance will get much better. Other notes: -The F-14 will for only a brief moment just as fuel runs out -The F-16 will accelerate vertically with a 50% fuel load, but only with ideal Wx conditions. (video coming soon) -The F/A-18 can but becomes unstable with fuel under 1,700 lbs and aerobatics should really be avoided this light. -MiG-29 and Su-27 probably can but the HUD is more difficult to read at 90degrees vertical. Actually the MiG-29A was worse than I thought but I only tried twice. -Mirage 2000C can but still not sure whats optimal for any of these aircraft. -Surprisingly, the Harrier struggles once out of ground effect, vertical, and nozzles aft but - again - I didn't try very hard (once). -I only consider acceleration using TAS and after air frame is at least 85 degrees vertical. Of the few hundred hours I have playing DCS, I probably have less than 5 in the F-15C. Id love to see what others come up with! Each engine produces its maximum thrust at a different altitude, air speed, and temperature. While they are much more efficient at higher altitudes and faster speeds, the drag on the aircraft is also much higher as the Mach number increases. This is why I start low and slow where the air is dense for the engine but slow enough that the total drag is low.
