Other than the 13 gram keychain camera attached, the rocket was a complete stock build, launched using an E9-6 engine. I'm upset because the cheap rubber shock cord broke during ejection and the rocket careened into the ground. The believe an E9-6 engine is not the correct one to use for this model (although that's what the instructions said to use). I believe with an E9-4 engine, I would have had a better flight and the ejection charge would have fired closer to the apex of the flight. |

Looked like a great flight until ejection. I think you're right about the E9-4. Pretty big bird for a 6 second ejection charge. You might consider contacting Estes customer service about this.

What do you mean? I should tie the elastic directly to the kevlar cord? Should I separate them with a swivel? How should I attach the kevlar cord to the rocket? Using the same type of glue on mount Estes uses? I already removed the damage portion of the tube... |

Tie the Kevlar around the motor tube behind the forward centering ring, then put a notch in the centering ring and glue the Kevlar loop to the motor tube and the point where it passes through the centering ring. Then knot the end together with the elastic. You can use a swivel to attach the elastic to the nose cone.

I did, and they're sending my the parts I need to fix the rocket. Hopefully, with a little Kevlar and a different engine - it will fly perfectly |

Looked like it weather cocked quite a bit, that'll require a shorter delay. Was it windy? Was there rod whip?
