>>1656436>was used only before ww2wood covered in fabric took a while to go away and the de Havilland Mosquito took it too the limit
hawker hurricane had fabric covered wings (phased out after 1939)
spitfire was all metal expect for fabric covering the control surfaces, this became a problem as the aircraft were up graded and got faster
axis forces also used fabric and wood but did not have access to supply of appropriate wood and glue
the Germans had got a head start in ww1 with all steel aircraft
but to get such a thing aloft was only possible after the introduction of ethylene glycol and improved engine performance and was relegated to slow ground attack aircraft due the the heavy weight
>>1625078for some cost reduction you could use S Glass
its the stronger grade of fiber glass that while slightly more bulky than carbon fiber compares favorably in strength to weight ratio
+ add some Kevlar blocks to the side so that when it falls over the shell is protected from road rash
