With todays advances in composites it would be very east to build a 130 inch Extra in the 16 pound range, it would be expensive but fairly easy.
You've obviously never built a 40% aircraft then. The LIGHTEST we've seen the all composite 40% class aircraft fully equipped is around 31 pounds from FiberClassics. I could see a bare airframe getting down to 16 pounds, but then you need to add everything to make it fly.
Let's see..
Airframe - 16 pounds
Engine - 10 pounds including mufflers, ingnition
Radio - 3.5 pounds (15 servos, 2 receivers, 2 Rx batteries, 1 ignition battery)
Misc - 2.5 pounds (wheels, linkages, servo extensions, glues used in construction, general hardware)
Looks like about 32 pounds here..
