Uncontrollable 747-400

Hi there! Unfortunately, the 747 has really outdated physics, meaning that stuff like this will happen and does happen.

Try using a lot of trim and carefully watching your speed and vertical speed. I’d also suggest flying some newer aircraft like the Boeing 777-200ER or the Airbus A350. You’ll find, for the most part, that the newer the aircraft is, the easier it is to fly and control.

Additionally, you can vote for the aircraft to be updated on the Boeing 747 Rework thread. A rework would greatly improve the aircraft’s physics and your overall experience.
