Having followed this thread from the beginning and watching closely as this was a plane I was considering buying, I would have to say this YET ANOTHER case of the manufacturer (supplier) stating one thing and delivering another. There is no way on Gods' green earth that someone can add two plus pounds of weight to a plane kit just with glue, not unless they glued a full bottle of glue inside the plane. If Mosquito Bite is claiming seven pounds then they in fact must be talking about their Balsa version only. if they are claiming their plywood version should be 7 pounds and it comes out over 9 pounds, well then I would call that a blatant misrepresentation of the truth. I the downloaded manual it is very obvious most of the pieces in the wings are in fact balsa wood. If that is the case and the heavier kit is all plywood, why would they have two different kits available, a balsa kit and a ply kit? Would that be because of the fact that plywood is a hell of a lot cheaper and good quality balsa?...most likely the case. Then, if that is the case they should in fact advertise it as such and not create false expectations of weight.
