I have a video I can send you if you like.
It's only about 2 min or less.
The ARTS spit out some weird data,
from what I could gather:
the motor burned for about 0.820 sec.
That I believe
then it came up with a really low ISP of 93.
That I doen't believe
I played with the data & came up with an I 550 or so...
