All's I have to say is the smaller the rocket, the harder it is to pull off DD. I gave up on it and use larger diameter rockets to do DD.
Getting the wiring in and small enough switches can be a PITA.
Did a G80 on an immaculately painted standard Apogee Aspire years ago when I first started back into rocketry at a "major" launch and it disappeared up into the nether world. The Wildman said over the P.A., "Well Kurt, I hope that was a single use engine!" It was so I didn't lose reusable casings.
A year later, I got the rocket back. It was found by another flier the same day it was lost and was turned in. Took awhile to get it back and I retired it. It was obvious the streamer deployed and brought it in safely though a long ways away.
I launched a couple of Aspires in a smaller launch site with smaller motors and as soon as I thought I should give up looking for them, I hear the "rattling" of the oversized mylar streamers I used with the rocket coming in very close to me. That was a rush if you ask me. Hearing the rocket coming in.
Come to think of it, I did do a G80 to offer up to the rocket gods a well used Aspire and that s.o.b. came down within sight and I retired it. Man, that was a long wait for it to come down and I guess the winds aloft were not that bad. I was getting ready to launch a gentle BP rocket when I heard the Aspire "rattling in"!
If one can, buy some aftermarket silver/gold mylar colored material. Get a long metal straight edge and cut as long a length of a streamer as one can. I forgot how long I did mine but it was long. Take the time to fan fold the streamer. I know, a real PITA.
Then, once the folds are set in the streamer, use a heat gun gently to set them some more. Once that's done and one is ready to fly, roll the streamer up and if it's too thick to pack into the Aspire, cut some length off until the streamer fits.
Cut a shorter length of streamer to put on the harness too. Why? Because the longer one can rattle up against the shorter one and if one is in an isolated area, you'll hear the Aspire coming in even if you don't have a visual. Your ears will point your eyes and boy that is so cool where one's ears point them to a rocket coming in.
I have to admit this only works well when one can launch privately by themselves. At a major launch with P.A.'s blasting might not be able to hear the rattle of the mylar streamers.
If one has an isolated site to launch up an Aspire on a good sized motor, can be a lot of fun with a long "noisy" streamer arrangement.
