🚨 THIS IS A FALCON 9 LANDING TEST - IN A LIVING ROOM. What you're watching is a custom EDF rocket. No propellant - a 90mm ducted fan inside a duct pushes mass downward, same physics as a rocket engine, just electric. 70mm fan on 7S makes 8kg+ thrust - thrust > weight = hover. Uses thrust-vectoring + PID like a real lunar lander. DIY VTVL for $250. 🛸🚀

🚨 THIS DRONE SWAPS NORMAL PROPS FOR 3D-PRINTED DUCTED FANS. Those swirling white shrouds enclose the blades completely. Ducted designs cut tip vortices, boost low-speed thrust, and make the whole craft quieter and safer. Experimental aerodynamics you can actually fly.

🚨 WHY 63% SOLDER IS THE ONLY ONE NASA TRUSTS IN SPACE 🛰️ Those numbers are tin %. Only 63/37 is eutectic - melts instantly at 183°C into a perfect mirror joint, no pasty stage. 30% & 45% stay grainy and create cold joints. 🔥 99% pure tin grows microscopic whiskers in vacuum that short-circuit satellites - that's why aerospace bans it.
