He skidded the airplane. He applied rudder trim so that the tail was not directly behind the aircraft. He also mentions trying to be nose high.

What this would look like I think. Slow down to increase angle of attack in level flight. The nose is now high (likely already occurred after flameout and ejection attempts without thinking about it - check). Go full deflection rudder trim to skid the aircraft. Now trim the ailerons and elevators to fly level based on drag and adverse yaw. Get out.
