From the README

Learn to hover and fly a helicopter, one step at a time, right in your browser.

The hover is the first thing a helicopter pilot learns, and the hardest. Four controls act on each other, and the aircraft answers every input a little late: the stick tilts the rotor, the rotor tilts the fuselage, and only the speed that builds up moves you. If you watch your position, you react four seconds behind and start to oscillate.

EC135 Flight Dynamics teaches that chain one piece at a time. A tutor hands you the controls one by one, starting from a hover that stands still on its own.
