RE: Wing loading ?
In our models it's often described in ounces/sq foot.
Take the area of the wing in square inches and divide that by 144. You now have the area of the model in square feet.
Take the weight of the airplane in ounces.
Divide the weight by the area.
The Fling 2M glider reviewed recently in R/C Report weighed 22.3 ounces. It's wing area was 477 sq.in. which would be 3.3 sq.ft.
22.3 / 3.3 = 6.75 oz/sq.ft.

To give you a ballpark area, that 6.75 basically means its a "floater" obviously. My prop jets are on the 30's which means it drops like a brick when the power is cut off.

RE: Wing loading ?
A low wing loading doesn't garrantee that your plane is a floater. See how far an electric foamy indoor plane glides without power. On the other hand, sailplanes can have surprisingly high wing loadings as long as the drag is low, permitting high speed flight without a lot of energy loss.

Well yeh, if I let go of a paper airplane without a little bit of a toss, am I going to expect it to takeoff or fall to the ground. I'm just telling him the blunt difference between the two.
