For all the non-believers..... do a search on youtube for sr71afan. There are a couple of guys flying giant scale blue foamies. Extremely light and they fly SLOW. It's all about low wing loading.

oops! yes it does... 1 ounce = 28.34 grams

After further discussion, I agree in the other post that it has to be filled with helium or some other lighter than air, inert, gas. That would explain the big fuse.
Hi..!!! Since it has been a couple years ago, any update about this matter..?
At the end, was it a fuselage-baloon helium filled??

No helium involved , just light wing loading .

Here is a home made plane with very light wing loading , so slow that at the end I'm walking alongside for a close-up !
