Hier is een heel interessante calculator, deze berekend ook de "Cubic wing loading", Deze waarde is eigenlijk veel interessanter dan de gewone wingload.

http://adamone.rchomepage.com/design.htm#calculate

A reference that is not dependent on the aircraft size is the cubic wing loading,
which is calculated dividing the weight by the wing area raised to the 1.5 power.
For instance, the full scale Cessna has a cubic loading of about 13 oz/cu.ft, which
puts it at the high end of a scale model category regardless of size.

Different types of model aircraft may have different cubic wing loadings (oz/cu.ft)
as shown below:

Model Type Cubic Loading
Sail and Park Flyer: 4 to 7
Sport and Trainer: 7 to 9
Pylon and Scale: up to 13
Electric Ducted Fan: up to 25

Beginners are advised to choose cubic wing loading values no greater than 8, as
it's likely to give relatively low take-off and landing speeds.
At higher cubic loadings one should expect increased landing and take-off speeds
assuming no special lift devices are used, such as flaps.
