Baby Bertha flying model rocket

My adaptation of and old Estes favorite, the Baby Bertha. (Some assembly required. lol) Should fly well on a standard 18mm engine. The C impulse engine should take it over 300'. You will need to figure out how you want to afix a launch lug as well as a shockcord and chute to the nose cone and sustainer. I haven not flown it yet. It might melt. I might not. It's only exposed yo heat briefly. The nose cone should fit loosely so it doesnt separate the loops of the airframe upon ejection charge firing. The motor should fit snuggly so it doesnt eject itself and leave the chute in the airframe resulting in a 3D printed lawn-dart. This is a work in progress.
