Description

This was the first time I have seen apogee of the EZI on a long burn at NEFAR above 9000 feet. What a sight!

I was able to use math to derive actual Gs from secondary axis. Accelerometer maxed out at 8gs on one axis for 2.25 seconds of thrust.

Simulation expected 8.2 Gs, actual was 14.83. Case and liner were nominal.

Is this data from your phone? It appears that the altitude & velocity were much lower with this device vs. what you earlier reported with the Stratologger? Or am I missing something here? By the way, what happened to your stratologger data?

Velocity is in wrong units - I'll fix it later tonight. I switched to MPH for the video and I forgot to switch it back - I'll change it back to its unaltered units.

Velocity is now back to its unaltered state of ft/sec.
