Power Loading/Wing Loading Equations
 

I remember reading an article in either MA or MAN listing some aerobatic, scale, and warbird power and wing loading info.
I need some help trying to locate that or similar articles.
It was probably within two years ago... I think.

I've got a .60 size Cap 232 that weighs 7# 2.5oz. without an engine and muffler. The weight includes an 18X6 wood prop and a 2 1/2" aluminium spinner.

I tried a Magnum 1.08 and although the power was immense, it weighed just over 9#s. A bit heavy me thinks!

Any help and/or suggestions would be greatly appreciated.

Thanks,
Jazzy

Power Loading/Wing Loading Equations
 

Jazzy,

You need to know the wing area. If you know that and the weight of the plane then you can determine wing loading.

Power Loading/Wing Loading Equations
 

Yes, I do know the wing loading at the weight I flew it at.
4.82sq. ft. @146oz. = 30.3 oz./sq. ft. (not including fuel)

There is a range where wing loading and power loading balance and performance is optimum. It is this range for which I search.

I'm kinda new to 3D so getting in the ballpark or even in the infield would be great. I'm thinking somewhere round 27 oz./sq. ft. would be great but; how much engine can I sacrifice and still have good performance? This is where comparison data and the power loading equations come into play.

If anyone would throw in their wing loading ,engine output #s, and performance characteristics I'd appreciate that too!:D

Sorry, Didnt know what you were looking for.

Someone on here should be able to answer your question.

I'm honestly not sure.

My 2M pattern ship (WS 74"), weighs in at 9.69 lbs with a wing area of 1065 in^2, giving a wing loading of 21.0 oz/ft^2. On a 60 size ship I would try not to get above 23-24.

Well folks, it looks like I found what I was looking for. After several hours of digging through old issues I came across several different articles relating to the subject.
The one which pertains most is found in the July 2001 issue of MAN. It tells you how to calculate the thrust to weight ratio for various props and rpms.

Thanks All,
