About the Mark ll ™
The Carlisle Rock-A-Chute Mark ll was initially released in 1957. it more resembled modern model rockets than the original Mark l which looked more like a fireworks rocket from the early 1950’s. although it’s market was small. It did provide inspiration for hundreds of successive designs.. The Estes Astron Mark was an improvement of the Carlisle Mark ll that used the newer model rocket engines. The nose cone was from a Leeds Sweete plastic crayon sharpener. The fins were stapled to tag board reinforcing strips, which were then stapled to the hardwood engine mounts.
The Retro-Repro™ Mark ll ™ is updated with precision laser-cut fins. The original plastic nose cone is replaced with a balsa nose cone. The original 18” parachute has been reduced in size to 12”. The original rubber shock cord is replaces with an elastic cord for longer life. The original method of attaching the shock cord has been replaced by a Kevlar cord for greater reliability. An engine hook is also added for ease of changing the engine.
