The near-space hypersonic aerodynamic glider has strong maneuverability in wide flight envelope. The glide is generally achieved in a smooth manner with no or weak altitude oscillations in the altitude. The maximum lift-to-drag ratio glide is a typical trajectory that can approximate the maximum glide range. which is a crucial indicator for a glider. https://www.spidertattooz.com/Estes-C6-5-ENGINE-BULK-PACK/
