Always good tips from the engineers on here, in my morning screen time im watching EAA video classes, huge resource there!
I have to say from 'blue collar' side of it, hand drawn plans or Vemco arm(pre-CAD), leave room for the buuilder to make changes that make final project unique yet similar. As a home builder(framing) I've gone back to the Architech to show where his roof design is 'asymetrical' and he laughs and says build it anyway want(not giving us redraw) then client asks/complain why upper floor room has lower ceiling than the rest...
I'm an over thinker yes, but quickly see where somthings are up to the builder and may not matter safe flight in an ultralight. IE:rudder horn moment, pull pull cables
