We tested the thrust of our motor and unfortunately the largest amount of thrust we got was 196 grams. That wouldn't even be enough to lift a model rocket off the ground. I think that our motor was so weak because the nozzle of our motor was a 1/4 inch hole and that didn't let enough pressure buil in the core chamber. Because there was such a small amount of pressure our motor was basically just a smoke bomb.
If I were to try to make another motor o would instead use a 1/8 inch nozzle.
