Hi,
I just bought the 757-200PW & -200RR in the sale and I’ve done a couple of Flights on it. However, I have found that the stabiliser trim doesn’t work. I click to drag it and it springs back to the default position and when I press the button on my yoke to move it, nothing happens. Note that no changes have been made in the control settings as it works perfectly fine on my other aircraft.

Also, how do I calculate the amount of pitch I need?
