Mine is done came in at about the same weight my scale isn't digital but it was about an ounce under 5 pounds, I had to put my battery pack beside the fuel tank as far forward as possible and put 1.5 more ounces up front. I got a few minutes today to fly my micro speedwing which was the first time I have flown all winter except my TREX in the basement so I'll probably put up a Dust before I fly this one just to nock of the cobwebs before I risk a new plane and engine.
