Robert,

I'd be willin to bet you could shed about 4-6 oz in just the wing alone, but it wouldnt be easy. My wing weighs a ton (1 1/2 lbs I think) with radio gear on board. I'd be willin to bet if you went with a single color monokote scheme instead of the three colors on top and the checkerboard on the bottom, you might save a couple oz in covering. The covering is just layered on, and the checks are layed over the base color as well. The fuse itself is pretty light, considering the size of the plane. You might be able to get the plane sub 7lbs, but it would take an ultralight 2 stroke/non stock pipe, a bunch of sanding, and the smallest hi torque servos you can find. Might be more work than its worth.
