[NRVR-Members] Head Count Check for Those Interested in a Hands on, All-Day, APC Motor Mixing Workshop, Fri July 19th

[Bob Schoner]

I’m 90% sure the motor is J impulse, still requires an L2 cert to fly.  If
they are getting K impulse out of a 4 grain 38 mm motor then they need to
share the secret with NASA!

The casting and liner tubes fit Loki and I think AMW hardware which is not
provided.

We are now calling all our launches research. Like Pat said it means
greater distance to pads and the waiver is reduced to 80% of the commercial
waiver. That still gives 8,000 agl for flying.
