The Easy Slide III is an exciting, high-performance rocket glider for 18mm engines. It combines elegance of form with simplicity of function in one superb glider. The wingspan is a whopping 18"! This bird was born to fly! Rocket gliders (RG’s) are one of the most intriguing and complex classes of rockets. The general idea is for them to fly upwards like a regular rocket but to glide back down like a plane. Sounds simple, right? The catch is that this transition from rocket to glider must be done without separating the model into different components. If the rocket separates into components (e.g., booster pod and glider), it is called a “boost glider” (BG). As a consequence of this “unity in flight” requirement for RG’s, there must be some change in the aerodynamic structure of the model that permits the transition from rocket to glider. In the Easy Slide family of rockets, QCR has chosen to effect this change in structure through the use of a sliding wing concept. In the powered and coasting stages, the wing of the rocket is tied back against the rear horizontal stabilizer. The RG thus flies as any regular rocket would. At ejection, the hot gases cause the wing to be freed from its attachment point. The wing then moves to its “normal” position, causing the rocket to glide. QCR rockets are performance-oriented. They are a common sight at NARAM year after year. I have built several models myself, so I can vouch for the quality of materials and research-based design. But don’t take my word for it. Check out the NARTS papers on optimality. You’ll see that these rockets are right on cue!
