Lay the kite on its back and unwind flying lines in the direction of the wind giving yourself clearance on both sides of the flying area.
Make sure the lines are not twisted, are of equal length, if one line is shorter than the other then the kite will always turn to that side, also ensure that the left line goes to the left of the stunter etc.
Pre-Launch check: have a quick look around you and make sure there are no obstacles or people in the kites flight path and do you have enough space behind you in case you need to back up quickly and be especially aware of any other kites in the sky.
If you have a helper ask him to hold the kite in front of himself facing you and into the wind. Now take up the slack keeping kite lines equally tensioned so that the kite launches straight up and the wind at your back.
If the wind is a little on the light side wait for a gust of wind before signaling your aid to throw your stunter firmly and smoothly into the air whilst you take a step backwards at the same time.
The kite will accelerate swiftly upwards without much contribution from the flier.
If you are on your own you might try the alternative of placing the flying straps/handles over a spike (large screwdriver) and inserting it into the ground. Then place the kite directly down wind of the spike with the lines pulled taut.
Stand the kite on its spine and wing tips leaning back to at least 30 degrees (to prevent the kite from launching by itself) It will now be possible to self-launch by lifting the straps off the spike and maintaining even tension on the lines stepping back smartly to launch the kite.
For beach launching lay your kite on its back with the nose facing away from you. Place a handful of sand on the sail between the stand-offs. Pick up the handles/straps and slowly take up the slack in the line. Now step backwards easing the kite into a standing position, which has the effect of removing the sand. Step back smartly, maintaining even tension on the lines, and your kite will launch.
