i am getting a hummingbird very soon, already ordered and stuff. i have some expierence with rc planes, and i fly cessna's in real life. so i can give my imput on that.

for the actual "flying" of the plane vs the RC plane is easier. you can feel the plane's movements, and you can feel stiffness in the controls as the plane gets more stessed. for RC planes, you can rip the wings off and you wouldn't feel a thing. for rc planes, you have to remember 2 sets of controls. tail in and nose in, for planes you only have to remember one set.

what makes flying real planes harder isnt the flying itself, but what you do in addition. you have to monitor a lot of instruments, your engine status, you have to be constantly looking out for traffic, always keeping in mind where you could land if your engine went out, navigation, then just flying the plane.

so, as a parallel to the hardness of RC helicopters and real choppers, i would say that flying the RC version is harder.
