At 1:22 scale, fuselage diameter is 0.26 m.
Fuselage volume =Πd²l/4 =0.11m³.
The air inside would weigh 132g
Helium inside would weigh 19g, saving 113g
Hydrogen inside would weigh 10g, saving 122g

Even a vacuum inside would only save 132g. If that were the case, letting air in would only take it to 417g, still less than one pound and still VERY impressive.

I guess being so big and so light, flying outdoors would be somewhat impractical.

BTW, 10oz is less than 2/3 of a pound.

just watched vi, very nice, take a look at 3.09 it looks like its inflatable , so helium etc

There is no helium- it was a joke ... for 40+ years my mate and I have been joking that his planes are made of helium and mine are made of church roof

BTW, 10oz is less than 2/3 of a pound.
