What do the numbers on an Estes rocket engine mean?
The higher the number, the faster the speed. Higher thrust engines may be the best choice for heavier models or models with higher drag factors such as a larger diameter. The final number in the code gives you the timed delay in seconds between the end of the thrust phase and the ignition of the ejection charge.
How do you read a model rocket engine code?
It is the same with rocket motors. The number may be relative, but the higher that the number is, the faster your rocket will accelerate. The higher the number… the faster your rocket will travel! If the average thrust number was exactly double, you’d accelerate twice as fast.
