Chute Release is a small electronic device that holds your rocket parachute closed until it drops to an altitude that you choose. This is great for windy days and small fields when normally your rocket would drift too far while descending under parachute.
Simply wrap the elastic around your folded parachute and snap it into the other side of the release, then set the altitude from 100 to 1000 feet (30-300 meters) and you are ready for launch.
