With a little practice, I can do just about anything I want with this thing. I can make perfect vertical landings anywhere, including rooftops. It's nice being able to land wherever you want, grab the best loot from inside ceilings or exposed rooftop caches, and take back off again without worrying about dealing with zombies.
Just remember that pitching up slows you down because Space is also a brake, and you can also pitch up to lessen or stop forward momentum. I usually bring my nose up when landing to halt forward movement, then level out right before I land.
Another thing that is important is to click the mouse button so that you mouse controls your camera, and not your gyro, as opposed to the motorcycle.
