I did something new (at the time) on this when I built it. I went with a zipperless construction, single deployment with the chute being pulled out from the payload bay, instead of being blown out with the nosecone. I used a 50' kevlar leash that I'd used before with a Rocketman chute. I also attached the chute in the same location I normally did, about 5' from the nosecone on the leash. At deployment, it was picture perfect, except for the part where the chute was supposed to deploy. The harness stretched fully out, but because of where I'd attached the chute, the chute was still just inside the payload section. about 2' of the shroud lines were out, but not enough to pull the chute the rest of the way out. It landed hard. We walked out to it, and just pulled the chute right out. It wasn't tight at all. Took us a little bit to figure out what happened. Had I flipped the harness around to where the chute was attached 5' from the booster section, it would have been one of my best flights ever. Devil's in the details!
