This is a Clone of a LOC-Precision Forte. The motor is an Aerotech G40-4w Single Use. (old - purchased in 2003) This motor has a ring of 29mm Motor tube epoxied to the end to act as a motor block. Retention via Kaplow Klips. After landing, the motor block was still attached. It appears that the epoxy just let-go, and the motor exited the top of the rocket pushing the recovery out and the nose off. - No damage to the rocket other than a little charing of the inside of the motor mount. It will fly again.
