After finishing mine, I stood back and said WOW what a cool looking plane. Then I weighed it and said SH!!!OOT. My 10 1/2 pound plane just went to 11 1/2 pounds[&o]. Then I went to balance it and said DOUBLE SH!!OOT. I had to add another 8 to 10 ozs of lead to get it to 3 to 3 1/2" balance point. I hate lead[:@]! I have a Saito 1.80 in mine with everything pushed up up front. I built this thing as light as I could and bought ultra light wheels, tail wheels battery pack, ect... Is anyone else a little frustrated at the 10 1/2 pound claim and the adds and website recommending lightweight glow engines???
