I was planning to build mine with a ZDZ40 and my calculated weight including an allowance of some 8 ounces for glue and little things was about 12.75lbs and was even going to use dual 5975s in the tail on elevator so I think its possible to see one at 12.5lbs.

I bought CF gear and chopped out some wood from the fuse but never really got into building the plane and then I sold the ZDZ so I dont know for sure if I would have met my calculations. Now I think the ZDZ would have been too heavy anyway so I'll prolly build mine with a Saito 180 at some point and shoot for about 11lbs.

Mecam do you know how the Edge would balance with the 180 and two 2 ounce servos under the canopy, you said its noseheavy for you right?
