I don't see the term "MaxQ" very applicable here. The idea of Max Q is that you start at low aerodynamic forces and then accelerate via rocket thrust, with dynamic pressure increasing until the atmosphere density causes it to fall. For a projectile from this launcher, MaxQ is the second it opens the airlock of the vacuum chamber and releases it to atmosphere. Then it hits a wall of air, and dynamic pressure spikes to the maximum instantly. It is true that you get rid of the centripetal acceleration upon release, so to a degree you trade the centripetal acceleration for drag acceleration.
