I think a lot of our light weight is attributed to prior planning and composite materials. Composites have a pretty high learning curve, from what i've seen. We were lucky to have a parent that was experienced with it. We also design light from the start, so most of the structural stuff is kept as light as possible.
We still often get overweight by 10-12 sometimes more pounds. The first thing we do is look for any un-necessary motors or mechanisms, lexan that can be replaced with thinner stuff etc. It is not easy losing weight. Cheese holing is probably the last resort, it results in maybe 2-3 lbs lost.
