And here I thought the plane was flying in three dimensions as soon as you left the ground. ;-)

Tower Hobbies, if not your local shop, sells a paperback by Dave Patrick titles "Radio Control Aerobatics for Everyone" that is handy in getting you through most maneuvers - simple on up to Lomcevaks (which neither I or my current models are up to).

Think of "3-D" as flying your airplane like a helicopter or your helicopter like an airplane.
