Its called the throttle, throttle gives you lift, no lift no fly ... easy? Remember when you are landing the throttle controls RATE OF DESCEND and the elevator controls SPEED. Meaning you flare (you use the elevator to flare a plane) your plane to slow her down (causes more drag), if at that point in time she is descending too fast then give her some throttle to hold her up. That is the same principle as how you perform a HARRIER for 3D.

Like some have told you, come in with a pattern plane with a steep angle and she will speed up, come in shallow and she will be manageable. Its like when I first landed a EP pylon plane, the fuse is so sleek that it retains a lot of energy and if you dive, she picks up speed.
