Parachutes

How to Use Your Parachute

Step 1 - Pull all the parachute risers together and tie them in a single knot so that you form a smaller loop at the end of the risers.

Step 2 - Cut two 5 m ~ 15 ft lengths of flight line

Step 3 - Note: To prevent tangles, it is best to perform this step at the launch site. Tie one 5 m ~ 15 ft length between the payload suspension harness swivel and the parachute riser loop formed in step 1. Tie the second 5 m ~ 15 ft length between the parachute canopy attachment loop (sewn in the center of the parachute canopy) and the weather balloon.

1.5 kg / 3.3 lb	4.9 m/s	49 minutes
2.0 kg / 4.4 lb	5.6 m/s	43 minutes

Tip

We recommend using our parachutes with our Flight Train Kit which comes with 20 m / 60 ft of stratospheric flight line manufactured here in the U.S. as well as a precision stainless steel ball bearing swivel. This system is designed to lift a payload weighing up to 10 lbs. This is an excellent setup for minimizing the possibility of parachute tangles.
