Other 1
The environment. Humidity, winds, temperature.
Parachutes. Purchasing a commercial parachute (ripstop nylon recommended over plastic) can save time.
Improperly mounted electronics. Use custom built PCB if possible. If using stripboard (aka Veroboard), use Kynar wire, ensure proper electrical connection, then epoxy. Electronics should not be left to free float around the CanSat. Also, clean means reliable.
When testing. Always check your electrical connections. You can use a Digital Multimeter for this.
CanSat Competition UK Design Review 2018/19

71. CanSat Competition UK Design Review 2018/19
Other 2
Ensure that the requirements are well understood and re-examined regularly.
Murphy’s Laws.
3D Printing is a pretty expensive way to learn.
Designing is half the fun. Building something actually sturdy is the other part of the challenge.

Things take longer and cost more than planned – optimism bias.
