so, no-one have any suggestions/advice as to how i can get my Phantoms safely over mach 1 without disintegrating in a ball of flame...?
even though i'm not a huge jet fan, the Phantom happens to be my favorite jet, and when i do get the urge to fly jets, it's normally my first choice.
That was an issue with earlier versions of the Engine Mod mate. I highly recommend to fly Mig-21s anyway, the FMs are much closer to realistic, ask Bravo. 
F-4s in 4.12= absolute fubar.
Thorsten, read through some of my previous (and later) threads, mate - i mentioned twice that i have double and triple-checked that i have the latest Engine Mod, plus western's latest patch.
i specifically checked all this again, due to testing some even newer featured betas that aren't even released yet, and those work just fine.
i also mention that the Phantoms worked fine initially, and since then i have made zip/zero/nada changes to Engine Mod, but they now explode at mach 1, which i can only suspect has something to do with a wrong FM, maybe - but even there, i have tried every different FM available (Vega/Paulus, etc) and no difference - 1000km/h + = ka-boom!
MiG-21's are cool, but i hugely prefer flying a Phantom, as it is my favorite jet.
no working Phantoms = i stick to my trusty prop planes, thanks 
Eugene, a very belated reply and sorry.

I already assumed what you said and was simply to darn lazy to read the thread again.

As for Migs, I thought the same, really, always, until I learned to test and fly the Mig-21s-the 2nd Gen ones.
Man are they well crafted for a segment that does not fit IL-2..at all.

Then I read some more about them and do date I think as a pure dogfighter, they were highly better than F-4s, what made the difference in the later Vietnam conflict IIRC (e.g.) was the pilots.
Then again I can see your point, design wise-apart the PF /FL models and the early '21s, F4s, and especially my beloved F-5s and F-104s look classes better and are from a place where it is reasonable to fly them low and fast in a Western US desert theatre (something I hope to get going as WIP some time in the universe).
Cheers, carry on lads, +1, carrier ops rule.
F-4s were one of my first known jets as a kid when I learned to read, I read about F-4s and F-104s hehe.
