I flew a D16-8 Q-Jet in an Estes Make-It & Take-It and it fit perfectly, ignited instantly and flew absurdly high. It was recovered with zero damage to the parachute or shock cord (or anything else).

The new instructions are excellent and cover the new initiator installation technique and recommended max liftoff weights for each motor and each delay time. Consumers who read and follow these weights will be pleased. Experienced flyers may try them in heavier models if drag is low and there is no wind.
