Flyable Rocket with 18mm Motor Mount.

A printable rocket, compatible with Estes or Quest hobby motors, offers an optimal performance on C6-7 motors and can also work with B motors. For the brave ones, flying it with Aerotech composite D is possible but not recommended for beginners. The design supports launch from an Estes pad using a launch rod. With an impressive altitude of 1600 feet, OpenRocket simulation indicates that a large flying area is required. Printing necessitates a tall build envelope and adequate fan cooling to avoid sagging in the nose cone during printing. PLA material is recommended, but ABS or polycarbonate would be better options. Two-part or one-part nose cones can be used depending on performance; if the latter option fails, use a clay-filled two-part design with tight fit to prevent injury. Pre-flight checks include ensuring smooth launch rod movement and the use of kevlar thread to secure the nose cone. Parachute or tumble recovery is required unless flying in a grassy area, where the latter can be used. Stability check is crucial before launch, with the center of mass placed 1-2 calibres forward of the center of pressure (2-4 cm). Always adhere to NAR Model Rocket Safety Code and use fireproof wadding between motor and parachute for safety purposes.
