Think of doing my first 'large' rocket. Large meaning bigger than 4 inches around. I have some 6 inch glassed tubing in storage and bought a 6 inch nose cone from Jack. I want to use DD but using a tether. I figure I'll use a hollow space in-between two bulkheads near the top of the 'fin can area' for the electronics with a hatch or hatches for access to the electronics below and the u-bolt above that the tether latches on to. If that makes sense. Anyone have pictures of their tethered setup? --------------------------------------- Jeff Gortatowsky, Redondo Beach, CA | Twitter: JeffGortatowsky | Yahoo: indanapt "(Scientific) Skepticism is not a set of beliefs, it is a set of methods for asking questions about reality." -- Doctor Steven Novella
