Practice this high-launch technique. Prop the kite up against a bush, post, or wall. Reel out enough line for altitude and simply pull the kite aloft. If the kite sinks tail first, there might not be enough wind. If it comes down head first or spins, there might be too much wind.
Different kites fly in different winds.
Adding tails to your kite helps it remain stable in stronger winds. Lay out your stunter and lines completely before you launch. Check all connectors, unsnarl and straighten lines and tails. Be sure they are adjusted correctly for the present conditions. Be sure your flying lines are even.
