I just got my Into the Wind catalog, which reminded me of one of my favorite finds - nylon repair tape. As much as I love this stuff, I haven't heard of any other rocketeers using it. Maybe I'm the only one who has ever used too little wadding or mis-packed a chute above the 'chute pad? In any event, I have done this often and my rip-stop nylon 'chutes have the burn holes to prove it. Thus, the ability to easily and reliably plug said holes is a real plus for me.
I recently had to rescue a rocket from a tall tree. It was up high and MDRA's long pole is so heavy that I had to snag the Kevlar shock cord and pull. The last part to catch in the tree was, of course, the 'chute. I got it down but only one of the riser lines remained on the 'chute. To fix it, I applied some tape on each corner to patch the tears. One piece of tape lightly held the end of each riser line. I then had my wife sew through the tape to hold it all together. It's only flown once since, but the fix seems solid!
