    How to Calculate and Test Center of Gravity for Perfect Flights       Have you ever spent hours building the perfect toy plane only to watch it nosedive or flip uncontrollably on its first flight? The secret to stable, graceful flights lies in one crucial factor: the center of gravity. In this comprehensive 2025 guide, you'll master the art and science of finding and optimizing your plane's balance point. Whether you're crafting simple paper planes or complex balsa wood models, understanding center of gravity will transform your DIY aircraft from unpredictable projectiles to soaring masterpieces. Get ready to unlock the physics behind perfect flights!    🚀 Why Center of Gravity is Your Plane's Secret Weapon  The center of gravity (CG) is the point where your plane balances perfectly in all directions. Think of it as the plane's "sweet spot" - when positioned correctly, it creates stable, predictable flight characteristics. Here's why mastering CG ...
