Rats - where's that clapping emoticon when you need it? Great post, Brett!
I think that when people say an aircraft is easy to operate; they tend to leave the caveats unspoken - the Decathlon, for example,
is very easy to fly - for someone with a pilot's license, a couple hundred hours, and a tailwheel endorsement. Take a sim-pilot and stick him in a real one though; and what you've got is tin foil. More than that - take an experienced pilot; perhaps a
very experienced pilot without a tailwheel endorsement, put him in a Deke and you'd have a similar mess. Real aircraft need to be learned to be flown; and the primary teacher is experience.
Also - keep in mind a lot of the ease of flying comes from the
immediacy - the fact that you're currently actually sitting in the bloody thing and can feel every twitch and hear every little creak. The feel of an aircraft is incredibly important - regardless of the size of the ship. I'm a far sloppier pilot in MFS than I was in real life.
I mention the Decathalon because far and away the best light aircraft modeled for MFS in Long Island Classics' Super-D - utterly lovely but IMO WAY too easy to fly. While I've never flown the Deke itself, I've plenty of hours (about 200) in its twin brother, the Citabria, dragging gliders and can tell plenty of horror stories about what happened when this young C-172 pilot went for his tailwheel endorsement.

(roll...judder...bounce...bounce...BOUNCE...drag...twitch...learning to taxi a taildragger on a grass strip is an exercise in frustration. Takes a bit before it's easy, but unlike a tricycle-geared aircraft, you NEVER take it for granted.)
So yeah; a real aircraft
is easy to fly, if you actually know how to fly it. 8-)
FWIW, if you want an aircraft that REALLY imitates its real-life counterpart, go get Dodosim's 206 Jetranger. A white-knuckle, sweaty palms learning curve on THAT bird, let me tell ya!

Cheers!
