I'm working on a 38mm minimum diameter rocket to meet some very specific objectives. These include breaking mach 1, altitude exceeding one mile, and transmitting sensor data via telemetry back to the ground during flight. Have a 38mm carbon fiber airframe ready to go, along with one of the new Additive Aerospace 38mm 3-D printed fin cans and a Wildman nosecone with payload sled. I'd love to use a Jolly Logic Chute release, but am aware that John Beans recommends BT-60 (41mm) as the minimum. But the JL website notes that "some 38mm rockets may work." I'm curious about anyone who has used the JLCR successfully with a 38mm airframe. Parachute used? How did you wrap the JLCR around the chute? Any other tips or suggestions? May yet opt to go with thin-wall fiberglass BT-60 airframe, but would really like to stick with 38mm if possible. JLCR is a must to avoid losing the rocket.
