What it is:

Very slow forward flight in a very nose high (about 45°) attitude.

How to do it:

Start by entering an "Elevator". Let the model drop a little, then slowly add power until the vertical descent stops and it begins to fly forward with the nose very high- holding full up elevator (on 3D rate) all the while. Juggle the power to control the plane's attitude and forward speed. In a head wind, you may also have to juggle the elevator to keep the plane from rotating up to a vertical attitude. Use the rudder to steer the plane around in the Harrier attitude. Try to use the ailerons very little, as they will cause the plane to wobble side to side.

Trickiest part:

Recovery: Basic-

Simply add full power and reduce elevator to transition into normal forward flight. Advanced- after you get the hang of flying around in the Harrier, juggle the throttle to slowly lose altitude and do a Harrier landing. The plane will land on the rear of the rudder first, then add a little power so it doesn't smack the landing gear too hard.
