Really? I believe all the electric ARFS have a ready to fly weight range.
Got me there - of course electrics are weighed that way, and it would be a little more accurate if gas planes were advertised as weight with fuel. But the first manufactirer to do so will get a bunch of people not reading what the weight includes and call their planes tanks.
As far as thrust to weight, 15 pounds is ideal, but a 50 can usually still pull a 17 pound(dry weight) plane around decently, and most true 50cc planes nowadays are pretty big and have plenty of wing area to still make that 17 pounds float. Personally, though, if I had a 17 pound 50cc plane I would hope that included the weight of the fuel, because I have flown 18 pound 50cc planes and, while they were still plenty light on the wing, vertical pull suffered for the type of flying I like to do.
