As I try to get into duel deployment and air starting, I have come across a problem that I can't make sense of. If the top stage of your rocket also has duel deployment, what will happen to the ignitor that starts the top motor? (Assuming the electronics are in the top stage) I don't know if the rocket in this image was intended as a second stage, but I find it fits the situation I was planning. Note the small tube in the engine mount that the igniter would go through to get to the motor. When the body tube separates for drogue deployment, will the igniter prevent separation, or will it freely slide out of this tube? I am wondering if anyone has experience with this design, or if my idea is simply flawed. If I have not explained myself fully, let it be known. Thanks
