I'm with you JRF. I bet the weight of the airframe with no equipment is 1600 grams. Which is pretty light! It IS too good to be true that a .40 size airplane with engine and radio weighs 1600 grams. Unless it's made from..well I can't even think of a material light enough to come out at 1600 grams ready to fly on a plane this size. Let the buyer be ware especially when dealing with not so well known companys.

They could also blame it on typographical errors. Many imported plans/instruction manuals/box lables are filled with errors...always have and always will. And they could be lying, but I doubt it.
