How hard is it to learn to fly helicopters?
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.
