Dual-Rotor Helicopter — LEGO Experimental Build Two rotors. One frame. Pure mechanical balance. This LEGO helicopter experiment explores how dual rotors interact, distribute lift, and stabilize rotation without complex control systems. By adjusting rotor direction and spacing, the model demonstrates how torque cancellation and airflow symmetry work in real helicopters. #LEGO #Engineering #Helicopter #MechanicalDesign #STEM #LEGOTechnic #Aviation #LEGOExperiments #RotationalMotion | Dr. Engine

I’m not really a “crash video” guy and I’d normally never post something like this… but I’m sharing this for two reasons. 1. This is my friend Derek , and I’m beyond grateful that he and the 3 other souls on board survived what was a truly terrifying accident. 2. To all my helicopter pilot family watching this: things can go sideways in the blink of an eye. This is a reminder to stay sharp, stay humble, and never stop training for the unthinkable. High altitude power management training matters.
