Dale,
First of all, please allow me to congratulate you on having the only 102 inch War Bird in the world that weighs less than 30 pounds!
Regardless of that, we all know that a 102 inch model can easily weigh 45 pounds and still perform quite admirably. My Aerotech P-47 is only 82 inches and weighs 34 pounds. With that in mind. I suggest that you add a couple of "Wing Tanks" or "Bombs" that weigh a couple pounds apiece and you'll be all set, the plane won't even know they are there! One last thing, I have NO agenda with the FAA, AMA, IMAA, ASPCA, SBA or anyone else. Simply Put, I'd like to see this type of event here in the USA before I die and since nobody else wants to do it, I thought I'd give it a shot. I DO believe that large models of this size are well thought out and are perhaps safer than some smaller models. I also KNOW that one cannot build an 80 pound airplane out of balsa wood sticks and cover it with tissue paper, mount a 100 cc shaker in the nose and expect it to stay together. The size alone dictates the materials that will be used, and therefore, should produce well constructed, safe airframes.
