I'm adding a JL chute release to a 4" Mad Cow DX3 and I'm wondering about where to attach the chute. My DX3 has an AVbay and forward section for future use, and I'll be using motor ejection. I've checked through the forums and came up with 2 main ideas. I want to start with using a drogue just in case I do have problems with the main, but in the future I'll probably switch to a parachute with a hole to use for stabilization.
1. Single line. 18" drogue attached to forward section, 48" main chute attached 5ft from forward section and 15ft from lower section on a 6" leader.
Pros: Simple, limited chance of line tanglement. Cons: Main needs to pass the upper stage cleanly.
2. Dual line. 20ft between sections. Separate line of 300# kevlar attached to upper section with 5ft to main chute, and another 5ft to drogue.
Pros: Drogue holds main out of way of rest of rocket. Main deploys and when inflated drogue just falls to side. Cons: Increased chance of line tanglement. Complexity.
What do you more experienced folks think?
