I can trim the Mustang easily with the WH HOTAS Trim button with 40 to 42 MP, level and fly pretty much hands free until I disturb the line. Thats right, not forever lol. Actually, not bad up to 45.
You should be able to do the same. Try 40 - 42 MP level flight, then trim and see what that does for you.
Yeah taps on the button. Dont screw with the trim wheels if you can map it.
Damn Torque, damned physics, sheesh!
