    Finally watched the video on how to attach the cord for recovery on the upper section. It shows taping the kevlar around the capsule and use package tape to hold it in place. Seems sketchy after spending months on a build and paint. I don't like it. Did anyone who bought the kit do this method or did I miss something in the videos? Also, this is why paper instructions should be included also, so I don't have to click on a million videos to see if I skipped a part earlier and forgot.

    I'm building their Saturn V and questioned the same thing. I would have preferred the option for an attachment point like on the Estes version. I also would have liked to have had a hard copy of the instructions, finding the last step completed on the video after a few days of not working on the rocket can be tedious.

    Ya maybe I'll brainstorm on something else. I really don't think I'll want to tape the shock cord around the capsule.

    I think this just might work. Tie a knot on the end of the kevlar and friction fit the nose cone on VERY TIGHT with masking tape.

    I can actually pull on the cord pretty good without the knot or the nosecone even friction fit on. Its gonna work just fine.

    Damnit, that might cause a zipper. Hmmmmm.........

    Would a thin layer of epoxy inside the body tube prevent a zipper?

    Ok, well I think I've decided on drilling 2 small holes in the nosecone and looping the cord through and tying a knot.

    You could do a variation of what I did on my Estes 1/100. I used the loop wire lanyard in the instructions, but instead of putting an unsightly looking loop in a weird spot, I disguised it at one of the omnidirectional Scimitar antennas on the service module. There are two of them, 180 degrees apart from one another.

    It should be possible to do something similar with the Apogee, then it becomes a matter of reinforcing the area inside the tube so it doesn't rip out and using the Kevlar cord in conjunction with a snap swivel lanyard. In the image below, you can see the loop on the left side of the service module. When not flying, detach the lanyard from the loop and build up a cover for the antenna to make it look like an antenna or skin it over with some white glue and paint the skin silver. When it is time to fly again, remove the skin and again you have an open loop to attach the lanyard.

    I've simply made a slipknot to go around the SM.
