Hi,
Make sure you use the same swing speed as your 7 iron, fairway woods are long and don't need to be swung faster to get the ball going, a slower swing will be more controllable.
Place the ball in line with your right armpit (If you are left handed) and move your left foot back so that your sternum lies just behind the ball, try to sweep the ball away so that the
clubs loft gets it into the air, don't try to help it!
