| Tumble recovery model rocket kit, reminiscent of rockets of old. Patterned as a reduced semi-scale version of a model rocket from the 60's, the Tumbleweed brings back the excitement, fun and education of a tumble recovery model The Tumbleweed flies straight and true, for one half of its flight. At peak altitude, the motors ejection charge (normally reserved for pushing out the nose cone and a recovery device) is instead used to kick the motor back, into such a position that it makes the model unstable. In this unstable state, the model tumbles harmlessly to the ground, ready for another flight! A supplied engine hook holds the motor in place and prevents it from being kicked all the way out of the model. A large ring, at the base of the model, provides additional stability and strength. Accustom to rough landings, this model still needs to be built rugged to withstand repeated launchings and landing, especially if your launch field is hardpack. Below is a photograph of the Tumbleweed on the pad at the 2001 Grand Rocket Day, ready for launch! |
