This may prevent your plane from crashing!

"A nose-heavy airplane may not fly well, but a tail-heavy airplane may fly only once."

This app will calculate the POSITION of the Center of Gravity (CG or CoG or Balance Point) measured back from the leading edge at the wing root in the units of your choice.

Enter your measurements for:
- tip chord length,
- root chord length,
- sweep length and
- required CG percentage (eg 28%)

of your model airplane and then the CG, wing area, geometric mean chord and tip-to-root chord ratio will be calculated automatically.

You can use inches or centimeters and the result will be in the units you used (don't mix units though).

A too rearward CG position can cause unrecoverable (potentially fatal) instability!

25-35% recommended for most conventional wings, 12-18% for pure flying wings, 15-19% for Delta wings.

This calculator uses the Neutral Point, the AIRCRAFT'S aerodynamic center (AC), as a reference point to calculate the CG range. It uses a well known, simple but fairly reliable method of determining the CG of a model aircraft.
