Oh what a can of worms a couple of little nuts have opened up. I guess I'll have to remove the hardware in question, avoid deep ponds from here on out (and add a 1/16" to my drag disks to make up for all that lost drag area )! LOL..............
I use nuts and screws through the hull to hold things down. Just keep them below 3/8 16tpi. Some people will find problems with any ship, usually after a battle and with the internet as insulation.
Honestly i would expect better engineering from Tyng Tech shipyard, like a 3D printed fairing that snaps onto the nuts or something, or custom designed faired nuts
Found this post I’m looking to shed some weight on my sons Duca getting her down to 8lb. Do you have part # and resource that you purchased the plastic mags from? Be great to recreate those and install them
Steve's not around anymore dude, sorry. I think @Beaver may be able to point you in the right direction, as he's pretty fluent in the McMaster-Carr catalog
