QU8K Model Rocket

thingiverse

This rocket is a smaller version of Derrick Deville's QU8K project. Derrick successfully launched his QU8K rocket at Black Rock Desert to an astonishing 121,000 ft as part of the Carmack Prize entry. http://ddeville.com/derek/Qu8k.html Take the full ride along here: https://www.youtube.com/watch?v=rvDqoxMUroA Details on the Carmack Prize can be found at: https://www.space.com/13245-amateur-rocket-qu8k-carmack-prize.html Here are some tips for this project: Print slowly for the cone and fincan. The coupler, baffle and centering rings are internal to the rocket and can be printed a bit faster. The 24mm motor mount is mounted flush to the base of fincan. Use JB weld where the motor mount will attach to fancan that will be in contact with most of the heat generated by the rocket motor. All other components can be bonded with 5-minute epoxy for strength between the PETG and the cardboard tube. Without paint or shock cord or parachute, the rocket components weigh 5.5 ounces. With a fast burn E or F-class motor, this rocket can really take off the skies. The motor retainer was designed with the Aerotech 24/40 in mind, but due to the light weight of the printed parts, this rocket can also launch on "The Mighty D Motor" from Estes. An adapter and motor block will need to be adapted to use Estes 24mm motors. To do the small QU8K rocket justice, just hammer it on more powerful Aerotech reloads. It is unclear whether or not the retainer will handle Cessaroni Technology Inc (CTI) 24mm motors. Edit: 01-29-2019 - Added .25 motor retainer for use with the Aerotech 24/60 RMS case.
