Cool, guessing you’ll be awarded a Swiss Cheese Strut Badge
9mm thick Struts? Already seen “Strut plates were designed to be up to 6.35mm (¼“) thick.” from LR3 docs > strut-plates. Maybe thicker Struts are ok for Rear/Bottom, but not Front where the Core clearance is tight.
I recall Ryan/others mentioning gantry (torsion?) twist being a potential performance bottleneck… Wonder if ACM based Struts with a slightly different design, e.g. top/bottom flanges that cut/fold somehow to make angle bracket and/or boxed Rear/Bottom Struts could somehow help make the gantry even more rigid. Sorry, I don’t have a complete thought/idea on this yet, hopefully this word salad will spark a crisp workable idea in someone’s head?
Maybe ACM (alone) isn’t the right solution, maybe tensioned steel cable weaved between the ACM Struts would be needed instead/as-well?
