I beg to differ. Just look at the example Tripple-J provided with the shrunken heads. The size was reduced and the weight has not increased. They simply boiled away the unnecessary stuff. So, Sandbagger, stop boiling perfectly good airplanes!

The connecting rod out of my brain, my brain,
From out of my arse take the camshaft,
And assemble the engine again."
