Interesting findings, Lost in Isaan.
I think we could use some charts to compare the fuel burn to the sim values.
I was at a FL490 cruise with 0.85 and had around 21.00lbs/hr on the individual gauges while the sum up gauge showed 17.000 or so. I have no idea if this is close to real, but at least it's far away from the too economic flying with 0.60. Would be interesting to find out which fuel burn rate is closer to the real values there to pinpoint the faulty gauge.

I think if CS alters the fuel burn and the drag curve at lower altitudes, this fun thing will be as realistic as it could be for the placement in the market and the very nice price.

I don't know if the relationship can be described that easy, Mark. But you right, the edited fuel flow might have to be edited again if CS increases the drag component.

My problem isn't the overall speed of the bird (it's a powerful one, no doubt) but the too fast acceleration after TO and with gear and flaps going up.
Normally, setting climb thrust and pitching the plane up will establish ATC approved speeds but on this one, it all happens too fast from e. g. 180 knots to 300.
I can't remember any B-52 videos where the engines where throttled back that much together with a need to pitch up by such huge amounts.

So an increased drag should hold back this fighter like acceleration tendency in the sim, not more, not less.
The later climb phases look good to me, the initial 10.000ft are the problem in my eyes.

No bank issue here but I'll try that fuel flow value, thanks.

So is there any verdict?

I assume everyone went with TurboFanDude's mod file and settled with that.

I've just started flying this bird and find it like a rocket. I'm overspeeding and ruining flaps in just a few seconds after leaving the ground for pete's sake.
