hi im about to buy this rocket, but what do u mean it always fails to open

[Swatrecon]

since the rocket is really tall, the blast that pushes the top off so the parachute can come out doesn't work well.

Well the motor is a friction fit, if you don't put it in tightly enough, the ejection charge can eject the motor instead of the streamer (or parachute if it's a newer model).
