I am noted for building light weight models. Most of mine are exceptionally strong too. All my planes have come out below the kit listed weights. The plane I own with highest wing loading is a lightened sturdy birdie with a 62" wing. I am possibly over sensitive to wing loading.
There are others that are even more attuned to light weight such as the indoor electric crew.
I will have to weigh the dreamer not just pick it up and guess.
