You have the correct size motor hook for the Sprite. The hook is supposed to the motor in the rocket so that it does not get ejected from the rocket. However, the casing is supposed to slide back during ejection. Otherwise, the Sprite would lawn dart if built with the shorter EH-3 motor hook. The older Scout (Estes K-1, Semroc KV-4) works on the same principle, but uses standard motors instead of the Short motors.
