Thanks! I’m delighted to hear that you and others found this thread useful and informative!I saw the YT video of your flight earlier this month, and your thread answered my wife and my's question about how HPR levels work in Canadian rocketry.
I appreciated this thread, so much to learn from it.
Thanks for taking us along, and congrats on your L4!
Correct! And you do need to be a CAR member to fly there for insurance purposes. This is true for all CAR sanctioned launches. A NAR or TRA membership does not count unfortunately.great news!
Rage at the Gage I assume?! (DO they allow non-CAR Canadians to fly there?)
Yes. With an Additive Aerospace camera shroud.For your onboard video, are you using a RunCam 2 4K?
I’m still learning, is glassing the fins not as necessary on a fiberglass rocket? If you fly on N and O over Mach as you hope to later on in the thread, will it be an issue? I’ve been admiring this kit for several months now and hope to one day purchase it.The fin tabs were then sanded and wiped with isopropyl alcohol in preparation for epoxy.

I 3D printed a jig to ensure proper alignment of the fins.

One at a time, each fin pocket on the motor mount was filled with 55 ml of epoxy and the fin inserted.

The fin jig was slid into place to hold the fin in the correct position and the entire assembly was left to cure with the fin oriented vertically. The remaining fins were also fitted in place to help keep the fin jig correctly positioned. This process was done a total of three times to attach each fin.

Here you can kind of see how the fin pocket effectively guides the epoxy to encapsulate the fin root:

It shouldn't be necessary as long as you use a quality epoxy and properly prep the surfaces prior to bonding. The epoxy dam method I used during construction made it easy to create very beefy internal fillets which resulted in a fin section that feels very strong, even before adding the external fillets. The fins themselves are cut from fiberglass plate that is plenty rigid by itself. I have no concern about the fins surviving a flight on an N or an O.I’m still learning, is glassing the fins not as necessary on a fiberglass rocket?
