Figure 1.4—Large loop of string.
Open the parachute and feed the knotted end of the loop through the loops on the top of the parachute, and tie a knot. Fluff the parachute and open it slightly. This will ensure that the chute opens upon flight termination. Cut out a small length of string (about 18 inches) and place it to the side. This will be used later to tie up the neck of the balloon. Tie the end of the string from the roll to the thick string on the bottom of the parachute.
If there are strong winds, generally sustained winds of 20 kts or more, a train regulator should be used. If a train regulator is NOT being used, wait to finish the flight train until just before the launch. Pull out about 12-18 inches of string. Tie the free end to the bar on the train regulator (Figure 1.5a).
The string on the train regulator is held down by wax. Free the end and feed through the eye on the bottom of the regulator from left to right. You will know that you have done it correctly because the string will reel off the regulator (Figure 1.5b).
