The guys at one of the LHS's here have been flying the firebird outlaw (the twin engine one) out in the parking lot, and one guy took some of them to a family gathering type thing, and had a 5yr old flying one around by himself in a couple of flights.

So, some park flyers are really easy for someone with no airplane experience, but others are a bit harder to handle. I have a GWS A-10 that is a lot of fun, but isn't something someone with no flying experience should try.
