If you don't mind building have look at this plane. A Bridi Aircriuser. I built one with a stretch wing because I was thinking about making it electric and it still only wieghs 3.5 pounds.I added a little more wood in the wing also. Built per the plans it should weigh about 3 pounds or a little less. Its off the ground in just a few feet and lands like a feather. Mine is powered with an OS FP25 and I fly it at half thottle most of time. I have posted a pic before but I will post it again.
