Thanks ! Definitely did superglue the shoulder. The shock cord that comes with this kit is pretty long, I haven’t had any problem with past launchesYour doing a good job, doesn't hurt to put a large amount of superglue at the very top of your body tube where the nosecone shoulder goes, really will help with zippers. A longer shock cord and pressure reliefs holes are a must, if you go to high power. Great job so far!!
Thank you, will update soonLooking forward to the rest of the build.
Got you, how long if I may ask? Kevlar? Just curious. My recent L1 cert flight, a freak ejection happened about 2 seconds after ignition. It was bad, but the damage was low. A longer shock cord isn't bad(too long is just a waste of materials at one point), as well as putting your chute at the end of the shock cord, instead of the nosecone. Just some personal info, good luck and keep us updated! I love good build threads and they are a great reference down the road. Thank you.Thanks ! Definitely did superglue the shoulder.

Michael, yes it is a Kevlar cord. The cord itself is about 8 ft and is mounted to the motor mount.Got you, how long if I may ask? Kevlar? Just curious.

L1 now, going for L2. I was just curious about the build, and what motors you were thinking of using. They seem to be really nice rockets.Michael, yes it is a Kevlar cord. The cord itself is about 8 ft and is mounted to the motor mount.
I do indeed tie my chute 1/3 of the way down from the nose cone to prevent any tangling in the chute shroud lines.
Are you an L1 now or are you working towards the cert?
Yeah I should have clarified haha. This is my third kit of the Zephyr Jr, but my first MPR. Now that you mention it, I am thinking about making the jump into the Zephyr nextL1 now, going for L2.

My apologies too. I saw it was the Zephyr Jr i TOTALLY misread this.... I thought you were going for the Jr L1 cert. Sorry about that, I'll butt out. Lol...
Oh absolutely! Again I apologize! I read it the wrong way but its cool. DD would be great to play with and that rocket. The Jollylogic Chute Release is also a very good tool to have. I myself plan in doing the same thing, playing around a little with smaller rockets and DD. I really had no idea they made a Zephyr Jr! Lol, ugh. I've been out of rocketry for about 10 years(I started with low power in 1990 at 7 and I still love these), got back into it in May this year with an Alpha III kit. Next thing you know I'm ordering parts for a scratch built L1. I fell back a bit, flew some low and mid power stuff then decided in September to go to URRG in NY just to watch and learn. After seeing a Jr member get his cert withna Zephyr. I said its time to go for it...Yeah I should have clarified haha. This is my third kit of the Zephyr Jr, but my first MPR.

With MPR, in my experience, they do tend to go high, even on 24 mm. I might experiment with adding a dual deploy bay to this rocket in the future to start getting some experience as I don’t feel comfortable going past 1500 feet on this rocket. As of now I’m only sticking to D and E engines on the zephyr jr
That’s awesome ! CongratulationsOh absolutely! Again I apologize! I read it the wrong way but its cool. DD would be great to play with and that rocket.

This is what I’m currently looking to achieve. This has been my 3rd zephyr kit and I’ve grown in technique after every build. This is why I wanted to start a thread, to document my process and aid others !Long story short made it(Mjne wasn't a Zephyr though)! The Zephyr is definitely a good rocket. They fly great on even a G80-10 with an adapter. And then they are 38mm so you have a wide range of motors. It would actually be a great rocket if your gonna go to high power. You can fly it without an H or I for shakedown flights. Then H/I for a the cert, then J for L2 if your daring...lol. Using high power build techniques on low and mid has been priceless for me, you are going the right direction for sure.
If I do add DD in the future, the extra tube length and bay would add some weight, so I would be able to diversify my motor usageSeriously though very nice and good luck, I'll keep watching for updates. I really love build threads.
I've also been having luck flying some 24mm rockets with an 18mm adapter for they are light enough, and they had successful flights too not super high. 29mm with 24mm too for smaller fields/areas with the same thinking. Making them heavier too helps.
Oh that's a really smart techniqueI then started to tape off my BT (Body Tube) spirals with gamita masking tape. The reason why I tape off my spirals are because I use CWF (carpenters wood filler) to fill in the tube spirals. This prevents unnecessary CWF to dry on the body tube where I did not intend to add CWF to.
