Forgot about grain collapse. Looks like some more research is in order.
It is rocket science after all :-)
Thanks all,

At 92 g's You could collapse the propellant grains and make a big

I'm thinking of flying a 4" Goblin (stock build + fin fillets) on a CTI
K2045. I've flown this rocket on a number of K motors including 2
successful K1100 flights. The K1100 flights pulled 40g's and reached
1,000 MPH. A K2045 flight sims to 92g's and 1100+ MPH. Any thoughts?
Also, does CTI V-Max propellant use standard delay charges or are
electronics needed like AT Warp9 propellant?
