Getting the hang of flying an R/C heli is a fairly challenging undertaking.
It's like riding a bike: when you first start trying it seems impossible,
but with enough practice it starts to seem easy, like second nature. It
may take 5 or 10 sessions to get to the point of being able to hover with
some consistency. Helicopters provide a long sequence of challenges, and
the corresponding satisfactions of mastering them. After hovering, there
is forward flight, nose-in hovering and flight, auto-rotation, aerobatics,
inverted flight, etc.
