LR3 -> LR4: The upgradening

Decided to goof around too after seeing Dan’s gantry twist experiments. Will measure before and after results based on Dan ramp test.

AI made me pick Loctite PL Premium Max.

I would do expanding foam but I really want to try to put my controller and wiring inside. Also relevant: https://www.youtube.com/watch?v=wtKBlMuDfCY

Oh! I see it now lol, I use chatgpt all the time for helping with .net dev. Funny trying to get it to reason out adhesives.

Honestly I bet just using superglue would do something, I was thinking PL because it’s thick and would kinda double as caulking and it’s been my go to for various other projects. The forbidden peanut butter.

Aza is nowadays first using Chat GPT, then a bit of his brain and then again Chat GPT. :smiley: Has been partly successful so far. :stuck_out_tongue:

Got it mostly painted and together. I got some PL Premium Max, but I’ll likely glue the gantry up after I get a few other things wired. I had some carbon fiber vinyl laying around, I think it looks neat. I’ll do the back panel once I have my wiring figured out and install buttons, fan, etc.

I really like the clean look you have achieved here with the 3rd strut plate, especially if you can get most of the electrical cabling inside. I wonder if the 3rd strut adds significant stiffness to the X-beam. Looking at some of the LR4 videos it seems the new 2 strut panel design works really well but I would think this closed beam idea offers more torsional rigidity than an open beam.

Nice build. :+1:
