Mclaren Clockwork Submarines

U46 is equipped with the smallest motor I've ever made,not easy when you've got big sausage finger paws like mine! however it didn't turn out too bad. The boat has no ballast tank because it didn't need one, its weighted to be able to surface run or dive by adjusting the fwd and aft planes and its performance in the wet stuff can only be described as somewhat frenetic! the small motor is deceptively powerful, this combined with the rotund hull throws the metacentric stability totally out of the window but vastly amusing to see, this gives U46 a giggle factor of 9.5.
