At this point make sure you are headed directly into the wind. Always maintain your heading with your ground steering, remembering as speed increases and lift develops ground steering diminishes.

Any Steering of the chute during takeoff must be extremely precise and that only comes with experience ad practice. Most of the time it may cause more trouble than help. Remember when the chute is loaded and under power it will tend to stabilize itself better than most pilots can. Once you are satisfied that the chute and lines are properly laid out the engine is started, warmed up and all pre-takeoff checks are done it's time to calm down and relax, there is nothing that will mess you up at this point as bad as anxiety. The secret to staying alive doing anything especially flying is keeping your calm so you can be fully observant and objective about everything you and the machine is doing.
