RC Model Aircraft Center of Gravity Calculator v2.2 (replaces v1.x)

(Note: please email if you have a problem or suggestion)

This may prevent your plane from crashing!

Measure and enter the tip chord length, the root chord length, the sweep length and YOUR required CG percentage (eg 25%) of your model airplane wing.

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. 

You can use inches, centimeters or millimeters.

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

25-30% recommended for most conventional wings, 12-18% for delta wings.
