What Other People Done
BYU-Idaho used a home-made chute for their first launch, without success: "...the parachute did not deploy very well. In fact, during a pre-flight test on launch day, the parachute was seen to deploy, then collapse. It is suspected that somehow, the parachute may have deployed partially, or not at all."
They also say the parachute was "[n]ot built according to any real standards, the parachute was our best attempt, and very little analysis and testing were put into its design"
1337arts used a plastic parachute which they all ready had on hand for their first launch, and a trash bag for a second launch.
