Fly the helicopter before a mission does. Lift, tilt, land.
Hold lift and wait: the rotor has to spin up, and there is no button to go down — let go and you sink. Tilt to move, and tilt back to stop, because the helicopter keeps its speed. Hold height in the first ring for 3 seconds, fly through 3 rings round the block and land on the rooftop pad. The light helicopter answers quickly; the heavy one has the slow rotor the early models are known for.
Controller, keyboard or touch. About two minutes.
