how do you figure wing loading?



thanks, DAN

Wing Loading
 

Wing Loading is the weight divided by the wing area. The usual units we use are ounces per square foot so you'll need to multiple the weight by 16 and then divide the area by 144.

wt x 16 /(area/144)

If you work the constants out you get 2304. So if you divide the wing area in square inches by the weight in pounds, you can multiply by 2304 and get the wing loading.

Let's say you have a 10 lb airplane with 1000 sq. in.
10/1000 = .01
.01 x 2304 = 23.04 ounces per sq. ft.

wow, this things a brick! its the dynaflight, flying brick,MUSTANG.

Typhoon- what type of model is this? For a scale warbird like a mustang, that doesn't sound too high.


Augh! Another person named Dan! There are just WAY too many people named Daniel or some variation here.

dynaflight mustang
 

hey Dan, the plane is an old 80s dynaflight mustang, funfly
kit. I will never build a dynaflight again. the only thing
good about the kit is the thick wing and the basic design. The
parts were saw cut , BADLY!! , DIDNT MATCH THE plans. The
wing saddle didnt fit the wing. it was a total nightmare. there
were booby traps every where. THE wing is done and looks good
, fuse is done ecept for tail feathers. I MADE ALOT OF MODS,
AND i hope i didnt weigh her down too much. ONCE I GET IT ALL TOGETHER, i will weigh it again. there was some wing sheeting
in the kit that was the toughest ive ever seen!!!! looks like it came from the middle of the tree, like nails. should be in the 5 to
six pound range. power will be a tower .46. I WANTED TO qiut
building this many times, but have weathered the storm. ha, my next kit should be a breeze!!




no one said it would be easy

Most .40 size planes have a little more wing area than that. The plane should still fly, it will just be a little doggy. Keep your speeds up on landing and don't try and touch the tailwheel first. Also, let her build up speed before trying to lift off of the runway. If you force it off you will probably be picking up the pieces after a tip stall and cartwheel.

some guys like flying bricks - scalelike they say--
an old rule of thumb is one lb =100 sq inches wing.
that is pretty good for planes in the 6-10 lb area-
as you get smaller - say 400 squares - halve that rule if possible
once you get to the 300 " electrics - halve it again .
Those numbers are hard to hit on most of the kits available - but most of em never get built anyway.
My 300 sq in Taylor Cub weighs 10 ounces - and flying weight will be one lb.- strange as it seems -it is on the heavy side----

I have that DynaFlight P-51... it's a very good flier, especially for being a P-51, which are notoriously poor in smaller sizes.
This one has flown well with .46 motors, .. I added flaps, ailerons and retracts, and it still performw better than you might expect.
It's not overweight either.
