can a 1st stage be tumble recovered of a 2 stage rocket in NAR competion or does this this violate rule 9.2? If lower stage ejects with the spent motor intact is this considered a “ejected motor”?
9.2 Ejected Motors
No entry in sanctioned competition shall eject its motor or motors in flight in such a manner that the spent motor casing or casings fall freely apart from the model. Ejected motor casings must descend with an attached and fully deployed streamer or parachute. The streamer area must be no less than 10 square centimeters for each gram of jettisoned mass; the parachute area must be no less than 5 square centimeters per gram of jettisoned mass. See Rule 9.10.
