The box for the Little Cap says 7.5 to 8.5 lbs. I think with a little effort, 7.5 is doable, which gives a wing load of 24.9 oz/sqft. Not terrible.
By contrast, this ARF Extra(which I own)states 7.5-8lbs, no wing loading available. This plane is built light and looks like it's made with balsaply swiss cheese.
I think mine weighs about 7.25lb with a Saito 100.
