Solid propellant rocket motor made of aluminium and steel with a diameter of 36mm and a total impulse of approx. 100-130N*s. It uses a mixture of KNO3 (64%), dextrose (34%) and iron oxide (2%). This mixture is melted on an electric cooker (at a temperature of approx 120-140°C) and while still soft, poured into the fuel moulds and a metal rod/screwdriver is used to create a central channel of approx 8-10mm diameter. The nozzle and cap are secured with 4 M5 screws. The engine has been successfully tested more than 30 times and no damage has occurred.
