Wing Cube Loading (WCL) Calculator

update.gif (1811 bytes) 28 Jan 13 - Added Calculator for Metric values.

The WCL of a model should ideally be the same as that of it's full-size equivalent if scale flight performance is to be achieved. Very high power military aircraft are very difficult to model at scale speed, therefore most scale modellers prefer to build fighter planes on the light side at about half the scale weight and half the scale power.

If you'd like to know more about WCL, please read this article.

Enter the Wing Area and the Flying Weight (in the units identified) of the model and click the «Calculate» button to give the answers in the following boxes.
(Note: Neither figure can be 0 or non-numeric).
