RC helicopters now have stabilization software and sensors that make flying one of them possible for unskilled neophytes.
When I was interested into such RC Choppas, I've been told to rather get a big one (like 6 ft main rotor), as their more stable, won't get blown around like autumn leaves by the draft of a butterfly's wing and even allow to take your hands off the RC-sticks for a few seconds to loosen up cramps...
At the end scuba diving turned out to be more affordable...
When they put that stuff in full sized helicopters, anyone will be able to fly one.
Well they all do have gyros... and tons of instruments about nav, elevation/level, roll, yaw, pitch, temp and air-density, weather radar, rpm, main rotor torque, blade angle, engine temp, oil temp, fuel temp, gear box oil temp, and what else not... (like that little red string on the front window...

)
And then you'd kneed to know navigation, mandatory flight paths, landing and departure corridors (within airports they have to stick to those like fixed wing crafts), fuel calculations, weather reports... plus the whole bible on FAA regs and radio lingo...
Alone the walk-around and pre-flights... you don't just turn the key and start... they don't have one
