Hey, I'm studying some of the formulas used (wing area, 3D wing area, wing cubic loading), and I'm very interested in the wing area and AUW of some of the models built here (primarily scratchbuilt but the kits would be fine here). I'm not really interested in a thread to discuss the pros and cons of the methods (there are lots of them out there already, ad nauseum) - I just want to plug in some numbers and see how they compare to what I'm estimating on the Martin 4-0-4. I'm late to the show on this, but still have options for making adjustments. Not really looking for opinions, thanks! Let's just keep it to specs... Kevin

I'm just doing some calculations on the 4-0-4 to see where she fits in compared to other scratch builds. I'm looking at wing area, wing cubic loading, and 3D loading as they are defined; plenty of web sites where you can enter the numbers and get a result and compare with a table. Do you have any scratch-built models weighing in around 4.5 to 5 pounds? I'm curious to see what your wing area is on these. I'm a bit late to the party doing this, but hey, you learn by doing! The 4-0-4 has been an exercise in using brain power, trying to figure out how to make stuff work. Thanks, Kevin

My new AN-2 is around the 5lb mark, it's a Bi-plane though.. . . . I'll get the figures on the wing area and wing loading data.

My BAC-111 is a bit more like 7 lbs Sir.
