I don’t think that will be an issue with a .6 burn time

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 boom! Fiber
glassing the fins will not help in that case.

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?
