(Discontinued-M) Edmonds Ecee Thunder Model Rocket Glider Kit

The Edmonds' Ecee Thunder rocket glider is a true rocketeer's delight! Its dignified boost and transition to glide can only be described as "regal". When you see this bird fly, you feel like you're watching a massive supersonic transport sailing down from cruise altitude into a smooth instrument approach.

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. Rob Edmonds has chosen a truly elegant way to effect this change in structure through the use of a movable "canard" concept. In the powered and coasting stages, the "canard" (the little wing at the front of the glider) is free to move around. This prevents it from generating any aerodynamic lifting forces. The RG thus flies as any regular rocket would. At ejection, the hot gases cause the wing to be pinned down, thus generating lift. This limitation of the range of movement of the canard causes the rocket to glide.

Try the Ecee Thunder with an E9-4 motor for a truly magnificent flight!
