Dr. Rocket casings are the bright red anodised casings you see at most launches. Additionally, limited production runs have made of some rocket motor casings in both green and blue colours, to commemorate launch events such as the U.S. LDRS launch event.
They are made in five different diameters and in several lengths. From 29mm. to 98mm.diameter.
Slack Pete's Rockets stock the 29mm, 38mm and 54mm diameter motors. We are able
to easily obtain all other hardware that Dr. Rocket manufacture.
They can be purchased as motor systems (most economical way), individual
motors or casings and forward and aft closures.
Let's take a look at some......
Here we have the 54/852-1706 reloadable motor system. This system includes the 3 54mm diameter cases, the 852ns case, the 1280ns case, the 1706ns case and one set of forward and aft closures. (The ruler in the foreground is in inches).
