I don't think this will be an issue with a .6 burn time

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?
