Why won't the motors start in Smart Mode on my Horizon Hobby Quadcopter?

The motors might not start in Smart Mode because the rate mode switch is set to low. To resolve this, set the transmitter dual rate switch to hi. Also, ensure that a GPS signal is acquired. Another potential cause is that the rudder trim is not centered; if so, center the rudder trim.
