@parislord - I used to work as a design engineer at GE Aircraft Engines, and that was one of the hardest things for me to grasp in the beginning - at both MIL and MAX power the engine will indicate 100% because the action of the AB occurs downstream of the core engine.
An engine is designed to operate at one RPM; that required to provide MIL power, per specification. Any other condition - part power or AB - is considered off-design. But as such, spec power physical RPM - MIL - is where/how 100% is defined, and what allows RPM to be determined and displayed as % of spec.

Sounds like the “A/C is glued to ground” problem, affecting some aircraft with the normal (OFM) flight model. IIRC it’s code issue and might have something to do with aircraft that are somewhat tilted on ground or so. While it was said that it was fixed, I continued to encounter this issue with the OFM. Was one of the main drivers for me to work on an AFM for the Eurofighter.

@Scorpion82 This has been fixed in 4.37U1 or U2
Not a reason at all to try going to AFM nowI would be highly surprised if you still have issue outside EasyMode in U2 in KTO/BLK/ITO

And yet. F4G, enter 3D on Runway, Training flight, push all the way up, stay glued still at 300.

Not sure when I tried it the last time, but back then it still didn’t work. The AFM has been developed in any case already (refinements apart). So it’s probably not worth to proceed with the OFM.

@Scorpion82 If you have AFM, for F-4, I suspect it is not stock BMS DB, so I can’t do anything for you

I’m describing KTO in my post.

@LorikEolmin - I’m surprised that if you are on the deck at 300 knots that you haven’t burst your nose tires…

Just tested this for fun no problems…
4.37.2 KTO F-4E, no mods, standard single runway, Huangsuwon or wahtever, half flaps full mil power rotate at 160kts with 4xAIM9 + 4xAIM7 worked fine on accurate and easy flight model.
I remember getting stuck on the runway with the retarded OFM F-18 flight model, rocked the stick a few times and it got up. -

Stay on topic.

F4E ROKAF works, F4G doesn’t.

The guy only said F-4… not very specific there.
Yes you are correct F-4G is not flyable. Reason is it does not do full control surface deflection. Fly both and you can easily see the problem. This is full aft stick…
F-4E
F-4G
-
F-4E ROKAF and F-4G are the same a/c (but the weight, and difference will not prevent one of them to take-off)
3d model are different, and as noted, I suspect F-4G DoF to have issues, but this has nothing to do with T/O speed
If you have issue with rotation at T/O with one of the F-4 and not with another variant in 4.37.2 KTO, I highly suspect your install being corrupted in a way or another.
-
That’s weird after a couple of gos I was able to get the F-4G to takeoff, did seem to stick to runway but rocked the stick a few times and it lifted off.

That seems to be a few corrupted installs then. I would rather check on the servers rather than on our part.

@LorikEolmin - I am on topic. You shouldn’t be able to get off the deck if you are skagging the stub of your nose gear along. So if you’re not off by rotation speed I wouldn’t expect that you could or should get off the deck.
Burst speed for the nose tires should be someplace around 190-ish knots, so if you haven’t rotated before then you should have additional problems.
-
Here is what I have with latest BMS level
Rotation before 120 KIAS, T/O around 190 KIAS -

I’ll post a video whenever I can.
