The Edmonds' Stage 2 Thunder is CiCi Stage 2's (much) bigger brother. As such, you can expect even stronger emotions when you open the package. The size of this baby will surprise you! The speed and altitude achieved with the D12-0 to E9-6 staging will amaze you! The simplicity and uniqueness of the design will impress you! This is a "must have" for your glider collection!!!
Just as the CiCi Stage 2, the Thunder is a 2-stage rocket in which each stage is a glider. While the booster and sustainer are together, the carefully balanced aerodynamic forces allow the Stage 2 Thunder to ascend like any rocket would. At burnout of the booster engine, the "gap staged" arrangement results in reliable ignition of the sustainer engine, which propels the Thunder's sustainer to obscene heights! At the same time, the aerodynamic imbalance brought about by the separation of the stages causes the booster stage to glide lazily back to the Earth.
Finally, after the sustainer engine burns out, the ejection charge imposes another imbalance in the aerodynamic forces, leading the sustainer to glide back to its proud owner!
