Minirocket Mach 0.8!

Thats a compleletly fascinating minimodelrocket which reaches with the right prinsettings a speed of about Mach 0.8 and half a kilometer of alltilitude. This can be achieved if you use 18mm engiens with about 20N thrust and a burntime of about 2 seconds, use for example the Klima D9 engien. And all that with a weight of only 4 grams with normal PLA and 2 grams with leightweight PLA. It can be launched from a shashlikstick and flyes really stable. There is no recoverysystem in it, so be carefull when launching its on your own risk. There are no section with infill despite the nose so you can set the infillsettings to 15%, it will work great. It doesnt need any support so you can print it without any of it. Set your layerheight to 0.15mm (practicly any printer can do that even old Ender 3s) for the best surfacetexture. You can also sand it after printing. It will take about 1,5 hours to print on an old Ender 3 and basicly on any other printer. There is one layer of PLA on the bottem of the engienhole to stabilize the print a bit. Just rip it away after printing with a srewdriver, you dont need it. I flew it 5 times and I will fly it even more in the future, its really fun. You can pack all the launchequipment in a small backpack and launch it wherever you want, the launchsetup takes 5 Minutes max.

Have fun and be carefull!
