Model rocket motors with thrusts from a few Newtons up to several kilo-Newtons are readily available. Snap swivel sizes range from size 1 to size 12. There's many types of model rocket engines for different size rockets, and for desired performance. Now that you have a basic understanding of power, you can confirm this is true: The "C" power rocket motor is about 4 times as powerful as an "A" motor. Black powder can be used used as a propellant with more consistency than zinc-sulfur and is the propellant used in small commercial model rocket engines. Single stage engine. Like zinc-sulfur, the burn rate depends on the particle size and how much it is compressed. Some airframes, such as 29mm and 38mm can be used as either airframe or motor mount. The value of these three flow variables are all determined by the rocket nozzle design. Dividing the thrust required by the specific impulse will tell us how much weight flow of propellants our engine must produce.
