This model will take off from hard surfaces like pavement but not
from grass.

After reading the manual listed on the above tower hobbies page, it does say....

Takeoff
Switch on the transmitter and make sure the throttle
stick is back (pulled towards you). Switch on the
electronic speed control. If you have dual rates on
your transmitter, set them to low. For the first flight
have an assistant hand launch the plane for you. This
will allow you to have both hands on the transmitter in
case the plane is out of trim.To launch the SuperStar
EP Select, grip the plane under the wing, keeping all
body parts away from the propeller. Switch the motor
on and toss the plane level into the wind. Allow the
SuperStar EP Select to gain speed and climb out at a
shallow angle before turning. The SuperStar EP
Select can also take off from a hard surface.
