RC Center of Gravity Scale Calculator

What this calculator does

This is useful for jets, scale airplanes, larger models, and aircraft where a normal balance stand is difficult to use. A correct CofG matters because a nose-heavy or tail-heavy airplane can be harder to trim, less efficient, or unsafe. Enter the main-gear-to-nose-gear distance, target CofG distance, and wheel weights. The result shows total weight, actual CofG, difference from target, and the nose weight change required. Example: after moving a battery tray, use the calculator to confirm whether the CofG moved closer to the target before the next flight. Always re-check the aircraft in its normal ready-to-fly condition.

In practical terms: It calculates actual CofG from three scale readings and compares it with the target balance location.
