This weekend I had my first early deployment in about 15 years. I've probably built a dozen of these 29/40-120 motors in the last year without any issues. My son's Ventris lept off the pad and then the chute deployed right at burnout. The rocket suffered from a 2-3" zipper. The tea bag shock cord mount held up and actually prevented the zipper from being any longer that it was. I believe I built the motor per the instructions. I took a picture of the delay end of the motor before I cleaned the case. It looks like the delay liner burned up the side. I'm not sure how that would have made the ejection charge go off. Maybe I didn't have enough grease on the o-ring?
