Old info; Apogee updated their site.
I've used a JLCR on a 75mm minimum diameter rocket using an M1315 to 21,200 ft. I did not use a drogue, but just bound the main with the JLCR. Apogee deployment of the burrito and then 20,000 feet of drop. It worked great and based on the altimeter readings deployed at just the right altitude (1000'). Due to some fin misalignment, this rocket coned significantly but the JLCR worked flawlessly. Good product.
When the chute release opened, the parachute failed due to excessive speed.
How do you know that? Was the chute damaged? I have experienced what I suspect was just the reverse that it did not inflate because it was falling to slow, but really that is just a guess.When the chute release opened, the parachute failed due to excessive speed.
...the noise of it opening in the sky.
I fly a LOC Mini Magg with a fair amount of weight in the nose. 1st flight with the JLCR the nose was falling way a head of the booster. Some told me to put a drogue on the nose cone. I have a 15" drogue on the nose cone and I place the main chute Jolly package about 3' down from the nose cone. Has worked perfect for 5 flights now. MG fly's great on DMS H-550ST

Earlier this month while retrieving my rocket about 3/4 mile from launch, I heard a faint approaching rushing noise in the sky nearby... Before I could spot it, I heard a loud flapping/popping noise and then saw a separated airframe falling fast below a now failed main parachute. I later learned that the rocket was a 4" diameter fiberglass rocket that deployed the main with a JLCR at a 9,000+ ft apogee without using a drogue. Unfortunately, as the nosecone was heavy, the separated airframe and reefed chute came down too fast. When the chute release opened, the parachute failed due to excessive speed. The rocket survived the fall.. but the lesson learned here is to make sure that the separated airframe components and reefed chute don't fall too fast. A small drogue would have been appropriate in this case.
