Golden Age of Transport is an interesting subject for a GB, certainly something that is on my mind every now and then - but I haven't actually built any kits for.
So I searched for a kit that would suit this GB and came across a Dornier Do X. The biggest and heaviest of it's kind that made world records that lasted past WW2 - and made a transatlantic test flight that lasted almost two years! It's almost as much as a boat as it's a plane. Pilot controlled two 'throttles' - left and right. But they were not really throttles, they simply signalled the engineers inside the wing - and they made the adjustments to the twelve engines, much like in ships. All in all, certainly a worthy subject of this GB!
