This 700mm (approx. 27.5-inch) research rocket is engineered for enthusiasts looking to move beyond basic kits. Designed from the ground up in Fusion 360, this build focuses on mechanical reliability and aerodynamic efficiency.
The airframe is split into three main segments, connected by precision-machined threads that eliminate the need for messy adhesives and allow for easy travel to the launch site.
Technical Specifications:
Total Height: 700mm
Diameter: 50mm
Motor Mount: 24mm (E-Class compatible)
Aero Features: Integrated "Teardrop" launch lugs and a 3:1 Tangent Ogive nose cone.
Structural Strategy: Variable wall-thickness booster for maximum strength at the fin-roots.
Printing Recommendations:
Walls: 2 perimeters for the mid-body; 5 perimeters for the lower booster.
Layer Height: 0.2mm for the main body; 0.15mm for the threaded sections.
Material: Tough PLA, PETG, or high-performance composites.
