I have a LOC 7.5 V2 kit as well and was planning on building it later this season with fiberglassed tubes and fins with dd.Last night I sat down to dry fit all the parts in the LOC 7.5 V2 tailcone.
I love LOC but I gotta say the the instructions were a bit lacking to the point of misdirection. I have built many HPR and don't need instructions but it did take me a bit of puzzling with the 98mm motor mount rings and the clever fore loading LOC 54mm motor tube adapter. The motor tube rings are so massive they have built in voids to pour foam down into the bottom of the tail cone.
I may or may not tend to choose builds with robust build threads in the past. This rocket purchase was very different in that I wanted to build this massive rocket and there are no build threads I could find. It may inspire me to do a build thread with some of the more puzzling bits of the assembly.
Great! 7.5 V2 builders unite! Send me any links if you find em. I have been looking since last fall and the closest useful builds were 7.5 Doorknob builds. I did finish the Nose cone with the adjustable nose weight system. its very clever.I have a LOC 7.5 V2 kit as well and was planning on building it later this season with fiberglassed tubes and fins with dd.
I have the version with multiple motor mounts, but not the one with adjustable nose weight cartridges (well, I do, but that's a side story for another build).
I think there were some build threads around if you dig. There's also some thread on the cartridge weight system as well as the adjustable dd bay (short or long).
Yeah, time to put that to bed.
There's a YouTuber here who had some videos of building one that he did tip to tip fg with. I'll update if I can find it again.Great! 7.5 V2 builders unite! Send me any links if you find em.

Finally...and well done sir!It's taken me 15 hours to realise this may have been a bed joke. That's how tired I am.
Kudos to you, Sir. Kudos.
must...resist...comment...Brushed Minwax wood hardener on some mushy cardboard tubes.
After drying they are noticeably stiffer.

volunteers like you is what makes it possible for everyone to enjoy this hobbyDrove to Seymour, helped to set up the range.
For creating my 3D models, I decided to graduate from TinkerCAD to something... well, more. Nothing wrong with TinkerCAD, but it lacks more advanced tools, and I need those tools. I fired up OnShape this morning and started learning the ropes. I'm working on a scratch Big Red Max, so a fin design seemed like a good place to start and this is what I came up with:

This design was inspired by @DigBaddy's Goblin fin that I upscaled for my 3-inch Hobgoblin. There are a few issues like the split in the fin tab is too long and the bevel descends beyond the horizontal plane but I printed it out to see how it compared with the LaunchLabs.com Vanderburn BRM upgrade fin.

If you look closely, the plywood fin is in the back... pretty pleased with the result. If you want the STL, it's attached. I also filled, sanded, filled, sanded, primed, filled, and sanded (ugg) my Hobgoblin replacement nose cone.
