Hi all

I use to know how to figure the wing load, but sadly I have forgoten. Can somone please refresh my mind. Thanks.

A 20# plane divided by the wing area of 5 sq. ft =--4# per sq. ft.
----------------------------------------------10------= 2#--------
# or oz. can be divided by sq. ft. or sq. inches, all combos work.

Total weight divided by total area of the wing, including the area in/under/over the fuselage. In oz per square inch or square foot.

oz/sq foot is more typically used for comparisons and shows up most often in various discussions or literature. And remember that to convert the wing area in sq inches to sq feet it's (area in sq inches)/144= (area in sq feet).

I am still a little CON. Lets say I have a 10LB plane that has 800 sq in. how would i get the wing load in Sq feet.

Sorry. what I ment to sat was To get the wing load for Oz per Sq feet.

160 ounces divided by the 800 square inches = 20 onces per square inch.

800 sq ins = 5.555 sq ft, 160 divided by 5.55 = 28.8 ozs a sq ft. Rad

Dad gummit, stupid decimals:

160oz/800in^2 = 0.2 oz/in^2

800 in^2/114in^2/1ft^2 = 5.555...ft^2

160oz/5.555...ft^2 = 28.8oz/ft^2

Yup, Radcliffe is right.

I need to convert 83 DM/2 to oz per square foot. Any takers ????????

Most model's area is advertised in square inches. At least here in the US by US retailers. And if not, it's easy to measure with a yardstick in inches.

So if you have the wing area in square inches, divide that number by 144 and you've got the area in square feet.

If you know the weight in ounces, the divide that weight by the area in square feet and you got it.

Hope this is simpler to follow.
