current FM development status

Speed curve for B version is done!!

Sea level: 1440 km/h

1500m: 1530

3000m: >1620

5000m: >1800

9000m: >2250

12000m: 2340

now that i find basic drag parameters for F-4 i can make other versions fast

Hi Vega, I hope I may put here some thoughts on the subject "speed" perhaps a little bit off topic....
Do you mean (this question is of course rethorical) this new FM should make possible to actually read these speeds (and with TAS accordingly)?
It sounds very interesting and much more if this could be applied to ALL aircrafts in game which, even if the overheating feature is disabled in "difficulty" tab, barely reach maybe 85 to 90% of theoretical max speed given a certain altitude...
I was told realistic speeds according to manuals are never to be reached (it's a online game so maybe not so important in the end...) due to game limitations which, in reverse, can simulate quite well stall speeds (and I wonder why)!
Anyway, sorry to bother and thks for your work!

Best regards,
Gianluca

Is it just me or does this thing seem very underpowered, and sluggish as hell, I can't turn with a mig even remotely, and can barely get a climb. And it stalls at 160mph.

The Phantom could never turn with a MiG, especially the MiG-17. However, the Phantom's strong suit was it's ability to outclimb and opponent. Often, Phantom pilots would go into the vertical to maintain the advantage in a dogfight. The Phantom is not a turn fighter, but an energy fighter.

Hello all. I installed the 4.07m to DBW 1.71 Superinstall; and installed the F-4's.. and getting a 20% CTD.. any idea why?

I don't think the new versions work on DBW, I know at least the early versions do

EDIT: NVM I'm just dumb

[Kazegami]

20% probably means you didn't install the 00000_000_NoOpenCanopyAI mod. It is required for the F-4 to work.

Mavvrikk, the F-4 is supposed to stall at high speeds, and can not turn with a MiG. It's a very heavy jet fighter... also, I don't know why you think it is underpowered. I can zoom climb to 10,000 meters from take off while accelerating the whole time at a 45 degree angle. Maybe you don't take the time to accelerate before attempting a climb?

[ANDYTOTHED]

Wrong, at low altitude it can turn inside a MiG-21

Thanks! that did it. I can't believe it was something that simple. I feel really dumb after that. lol.

...Which is of course well known for its maneuvrability...

Some that's been bugging me lately, may be a conflict not sure, but F-4 AI just crash into the ground a few seconds after QMB start. I've tried reinstalling the mod and that hasn't worked.

[hanspeterii]

That happens when you start at low altitudes because the AIs speed up before pulling up, so they crash in the ground while you pull up in time and then speed up (the default speed in the beginning of the mission is only 300 km/h I think, that is too slow for F-4 AIs at low altitudes). Also, the AIs increase engine power very slowly.

Try setting the mission altitude in QMB to a few 1000m, that should give the AIs enough time to take up enough speed.
