I was wondering if there is some kind of formula for finding the suggested weight for a certain wing area?

Thanks

Status: offline 		after flying multiple models I have come up with these rough numbers

300-500 square inches = 16 ounces per square foot
500-800 square inches = 23 ounces per square foot
800-1200 square inches = 28 ounnces per square foot
1200 -1600 square inches =30-35 ounces per square foot

of course all of these are ranges and approximate values. The bottom line is that the lighter the wing loading the better it will fly. But on the other hand a model with 1200 square inches and a wing loading of 12 ounces per square foot will get tossed around like a kite in the wind, on the other hand a 1200 square foot wing with a loading of 60 ounces per square foot will require full power and lots of speed to fly and fall like a brick if the engine quits. the 12 ounce wing loading model will glide with engine off...

So depending upon what performance you want pick your wing loading. In general the larger the wing area the higher the wing loading you can work with.

Hope this helps
