That's a great tip jmir. I agree you can learn so much about "3d" flying just from the "elevator" trick and its a very safe maneuver for a beginner. Once you can fly your plane down in a stable steep elevator (and even steer it around some), its not so big a leap to try harriers.

You should also try inverted harriers. While its harder for the pilot to think of how to throw the sticks when inverted, many planes seem to settle down better when inverted. Again, its a smaller step to go to inverted harriers once you've done inverted elevators.
