There are a lot of ways to slow down your plane to hit the runway when you're dead stick. Large S-turns, deliberate stalls, etc. If I have a light aircraft that doesn't like to come down, I'll just hold back the elevator and make it do continual stalls until the plane is at the right altitude and speed to land on the field.

On heavier planes that might snap over, I'll sometimes do a loop if I have enough altitude and speed. If it's at just the right speed and altitude to shoot off the end of the runway, then I'm probably too low to attempt much and I'll let it go off the end of the runway.

Experience with the plane will help you figure out what works best.
