Description

Semroc’s cc:X-21 is a rocket glider that is a modernized version of the Centuri X-21. Here is the original description for the 1964 Centuri catalog:

“Boost-glide aerospace vehicle! Exciting Performance! Advanced design! Plastic payload compartment! Controllable! Rocket powered flight straight up – hundreds of feet – then glide return for a soft landing. Successor to Centuri’s famous Aero-bat, the X-21 is easy to build and can be launched many times. It can be controlled to maneuver left and right turns for ease of recovery. It’s plastic payload compartment can be used to carry live biological specimens or light scientific instruments. Simply insert a new rocket engine, connect the automatic elevon release mechanism and the X-21 is ready for another flight. The completed model measures 18” from cone to stabilizer tip.
