This is the first motor design of my little rocket project I created. I used sugar fuel as the fuel which worked well (65% potassium nitrate and 35% sugar). This all got heated on a hotplate and stuffed into the rocket motor. I have tried super-gluing the nozzle on but I don't recommend that as it had failed before. I instead recommend using exoxy. Abs/Asa as worked fine for this small version but if you can I would use pagf or pacf if you are able to. 0.6mm nozzle if preferable, but had worked with .4. Lastly pla and petg DO NOT WORK.
