Custom-built Arduino logger. Arduino with SD shield to write the data, and a prototyping shield with inputs sampling GPS data, internal/external temps, a 9-axis motion sensor, baro, and some other environmental things. I think there are some loggers for sale out there though if you don’t want to build a custom piece.

What did you use to record all the data on the flight. We are trying to do something similar in OK with Civil Air Patrol.
