Arrrj but the space shuttle uses new age technology & materials. The Crapinson Flimsicopter has nothing like that tech, they just cut back weight by reducing metal strength & sadly safety. I can HOGE at 15degrees C at 10,000' @ MTOW 2,250kg in my AS350B3+ I have HIGE at MTOW 1,520kg same height & temp. with a B206BIII with theC20J donk
