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

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.
