Drone Simulators.
Understand what a simulator can teach, how to structure practice, and where virtual flight differs from a real aircraft.
Use a simulator to isolate one skill at a time: a steady lift, a deliberate turn, then a repeatable route. A useful model responds consistently to stick input and makes mistakes clear. It will not reproduce every real airframe, weather condition or safety decision. Start with the primer, then move into the control exercises in Flight School.
