Will forward your comment to Boeing's engineering department - maybe you'll get a suggestion award...

I suspect your comment was slightly tongue in cheek, but rest assured that there are folks in the Boeing design department whose sole job is to find ways to remove weight, supporting my belief that weight on an airplane is a bad thing...

On FS airplanes that carry passengers and cargo for a living (say, an MD80), if you increase its empty weight by 200 lb (0.24%), that's one fewer passenger you can carry under max weight conditions... In today's highly competitive airline market, the profit margin on some routes is the incremental revenue generated by a half dozen passengers... Take one pax away and you've cut your profit by 17%... Adding 200 lb to the airplane just for giggles might be a tough sell to the CFO...

In model scales, with our high power to weight and structural margins, additional weight's major contribution is manifested in degraded performance and increased stress on the airframe, and IMO the lightest model that remains within CG limits is best.

Cheers!
