Three Piston ejection systems for 54mm (2.1”) PML tubing. Made from scratch using PML components, but not made from PML kits. I made the discs and did the sewing. Two of these have discs at both ends of the short tube instead of one to add strength and reliability. I think one was ground tested, but these were never actually flown. Yes, one has a piece of nose cone attached… long story. Sell $15 for all three, plus actual postage.

I have a rocket with three rear ejecting chutes. The center one is for the drogue, and the outer two for the mains. My thinking is that once the drogue is out, I don't want anything that the mains could snag on when they come out later, hence the smooth nosecone transition thingy for the drogue-ejector.
