The Wing Volume Loading, also referred to as Wing Cube Loading, is touted in some of the literature as an ideal factor for scaling airplanes and was originally defined by Francis Reynolds in an article in 1989. There is some info on it, and a WCL calculator at <div>http://www.theampeer.org/e-basics/e-basics.htm#WCL The original article doesn't seem to be available on line and I haven't found anything that proves that it is better than wing loading. If one of you guys can find the reasons and some proof that WCL is better to use than wing loading, please let us know. We all want to get the facts on this one. Thanks.</div>
