Plane always pitching

I use a nf5a, with a HOTAS T16000, and my plane is always pitching. I tried to trim, SAS for other planes, deadzone and online guides, but nothing seems to help. What can i do to make my plane flyable?

What plane are you flying?

And how much fuel?

Some planes at certain fuel amounts are a nightmare to fly (P-51Ds with 100% fuel for instance) even if you trim.

Also remember trim is for a particular fuel amount, power setting and fuel amount. If you trim for 250 km/h IAS and go to 500, it will need updating.

they are flying the NF-5A French jet prem he needs SAS enable set for damping

Some aircraft have terrible SAS mode balance, which can often result the aircraft constantly pitching slightly. What is really needed is the ability to Trim + SAS

Tornados use to do this and it was annoying as hell, you can try reporting it if its a similar issue

But having never flown the NF-5A I cant say if it is the same or not

i usually bring full fluel load. But i can’t fly with that kind of pitching, because pushing the stick down only stops the plane from going up.
